Nook Color wifi loop - possible solution (seeking/connecting/disconnecting)

Cross-posting this from the CM7 nightly thread since it also helped someone else. If this hasn't been posted before, I hope it is helpful.
Just wanted to drop in with something I noticed regarding the wifi looping bug. I upgraded from 30 to 31 and started getting the issue out of nowhere. The wifi would just constantly loop between connecting/seeking/disconnected. Tried a bunch of things with no results, decided to go for a full wipe, installed Phiremod 5.1 from the XDA forums with the new Dalingrin's kernel (1.1 OC version released 25th March), but when I rebooted the issue was still there.
I honestly don't know much about networking, but I also noticed that I was having to hard reboot the router sometimes because the wifi would appear connected but not actually do anything. After a bit of messing around, it seems that both issues were resolved by simply disabling UPnP on my router. I have no idea if the problem was caused by it being a crap router (it is), or the way the Nook is connecting to it, but I thought it might help out some other people having the issue.
The router for the sake of reference is an old Netgear WGR614v7 cable router.
Sorry if this has been posted before. I just wanted to add that apart from this small issue, the nightlies have been pretty fantastic. The Nook is a week old and my first venture into Android. The CM7 and XDA communities are pretty excellent. Thank you everyone for all your work.

Unstable Wifi Connection on CM7

I'm having issues with the wifi connection having to be reset every few minutes when used. It seems to outright lose signal and can't even scan for networks until a reset. I'm on CM7 stable, using the latest OC kernel by Dalingrin. Anyone experiencing similar?

I have a similar issue.
From time to time (something like every 5 min), the connection seems ok (in the wifi pannel, it is stated as connected), but I can't access anything anymore by wifi. I have to disconnect and reconnect to my wifi router in order to make it work.
(I also use the last stable CM7... And apart from that, it's gorgeous ! )

So I'm indeed not alone in seeing this... interesting. Thanks for letting me know. As well, I agree, everything aside from the wifi works great and the tablet tweaks incorporated are nothing short of brilliant.

Mine is table with CM7 final and with Philmod 6, both with the 03/31 and 04/04 kernels.

same here - cm7 stable + 4/4 OC
just loaded up nightly 39 + 4/14/11A OC to try that combo

Is this not the same issue all over about AES? Check your router, if it's WPA2 it's AES, if it's WPA it could be AES.
CM7 and some routers have issues when AES is used, try to disable it.

installed nightly 39 + oc 4/14a no wifi issues so far

You mind Starring this issue on the Cyanogen tracker? Make sure you put all the relevant information as well as your Router HW and FW. Thanks!

I posted my remarks in a comment on the tracker.
But I'm afraid I don't know what you meant by "my Router HW and FW" ?

Can anyone else comment on this? I might just go down this route, but I'm wondering if there a few more who did similar and are seeing no wifi issue as a result.
Also, I'm surprised to see a CM7 final release with a wifi issue such as this. If it indeed is related to encryption (AES vs TKIP), that's further perplexing. While I could go about changing the settings for my router, I can't go about doing so for many others - particularly in public. As well, if I'm to tether from my N1, I'm going to do it with a password, meaning I'm to do it with AES as there isn't much choice built in.
I hate to say this as I'm impressed with the amount of work that went into (and normally always goes into) CM, but I figure it has to be said. To be fair, I'm not sure how widespread this issue may be (does it affect the version of CM7 on tablets, only?) but I'm surprised it can exist in a version of cm7 considered stable.

I'll try 39 etc but I suspect if they made changes in that regard they would have said to retest in that logged bug.
As far as I know, I've heard reports this happens on some phones as well, not just tablets, not just the NC.
And it doesn't affect most people, in fact I'll bet it affects a minority of folks. If it affected everyone I'm sure CM7 wouldn't have released that way of course.
And yeah I'm with you, I _do not_ want to use my N1 tethered with Open encryption, but not much I can do until this is fixed.

Did you try 39 out? This issue is MIGHTY annoying for me as it is kind of hard getting a company with 39 000 employees to back away from AES on the WLAN..
Also going away from AES at home means that I cannot have my access point using 300 Mbit 802.11N which also is a real bummer.
I found this at the CM7 bugtracker, look at the final few posts there is a wifi-driver to try out.

Also noticed there was a complete guide about pushing the file here: http://forum.xda-developers.com/showpost.php?p=11974146&postcount=22

So if CM7 on my phone works fine on wifi, that means a NC should work the same more or less, correct?

I guess you didn't notice who posted in that bug, and posted tiwlan_drv.ko in the bug?
Anywho, for me it did help my own and work AP's, but it's still broken tethering to my phone. So it seems better but not perfect, give it a try. Just make a copy of the original tiwlan_drv.ko and push the single file from that zip up in its place and reboot.

[Q] WiFi occasionally 'killing' routers

Search function is currently unavailable, so apologies if this is a dupe...
Anyways, I'm currently running Rooted Stock 2.3.4 on my N1, and I've noticed that whenever I connect to my friend's DLink router (DIR-655, I think) the Wireless will work for some amount of time, but eventually it will stop working. And not just on my phone, either - the entire router stops working (at least for Wireless requests. Didn't have any wired devices connected to it). Thing is, last time I noticed it, it worked for quite a while - hour or two, maybe - then everything broke about 10 minutes after I received an email... At that point, the router needs to be rebooted, after which it continues working just fine.
The router is using WPA2 encryption, for what it's worth.
I've noticed this with previous versions of Android, so it's not a breaking change introduced with 2.3.4 or anything.
Unfortunately, I don't have an awful lot of Wireless routers to test with, and I haven't yet found an opportunity to test at home, so I'd be hard-pressed to say whether it's a router/D-Link problem, or if it's a device problem...
Has anyone else experienced this? Would flashing a custom ROM (e.g. CM7) fix this? Or would I need a new device? Any thoughts on what else I could do to debug this problem? As I said, this is a rooted device, with an unlocked bootloader and the latest version of Busybox installed.

I'm running 2.3.4 and haven't had this issue with this version or any previous ones.
I've had my phone disconnect from Google Services (the icons turn white instead of green), but the internet stays on and all other devices work just fine.
I have a Netgear router at home and a Linksys one at work and I'm connected to both the whole time I'm at either place.

Hmm... That's interesting.
I've never had Google Services disconnect, but I do have another issue with data randomly turning off. That's not a big deal, as I can just turn it actually off then back on again, and all is good.
Anyone else able to chime in with their experiences?

I have had this happen with cheap, crappy routers. Sometimes upgrading the router to DD-WRT helps, sometimes it doesn't. I had an ASUS this would happen to all the time, and an Airlink that this would happen to occasionally.
This doesn't ever happen to my Linksys WRT610N, and it never happened to an old ZyXEL X550.
I'm going to say, it's just a crappy router.

Thanks. Not really what I was hoping to hear, but that's life.
Did either bad router ever have this issue with other devices? One of the other folks living there has an iPad, and never has this issue, so I'm inclined to say it's at least partly my N1s fault. Also doesn't happen with any of the PCs connected to it.

Yeah, they actually did occasionally have issues with other devices. Hard to narrow it down because I have a ton of Wifi devices. The ASUS also seemed to go down based on time... after so long, it would just stop working properly. The Airlink seemed to get stuck based on demand and range. If I had my phone or laptop at the far end of the house and started using it a lot, it would get stuck. It was as if the router decided it was too much work to pump its signal that far and it would get tired.
Stock ROM on my N1 doesn't seem to allow it, but if you have a custom ROM, you might see if there is any way to set the Wifi to G-only. I had noticed on my old router that G wireless devices seemed less demanding for it.

Frustrating wi-fi reliability issues

My Droid 4 seems to have issues maintaining a wi-fi connection to some networks.
At home, it will connect and work for a while, but eventually stop passing data. It will still show connected, though. It will stay in this state until I turn wi-fi off and back on again.
At work, it often has issues connecting and will show "authentication problem" even though the credentials are correct. With enough trying, it will eventually connect, but won't stay connected.
iPhone, iPads, PCs, Macs and other types of Android phones work OK on these networks.
My old Droid 3 had the same issue.
On some other wi-fi networks, it seems OK.
What gives?
I'm currently a recent build of CM9, but it did the same when it was stock 2.3.6.

Ugh, me too and it was driving me absolutely crazy. I'm on AOKP now (think the build from a few days ago) and it (WiFi) works perfectly now. I know this, because mobile data keeps dropping (argh) but I'm still getting e-mail, etc (but I can't send MMS at least).
Most days I am in solid WiFi coverage, so I am dealing with dodgy mobile data in exchange for stable WiFi. Anybody know if eclipse fixes this issue?
Edit: I'm glad you made this post so I know I am not crazy. Part of the changelog for the 219 update was a WiFi fix, and I was very disappointed when it didn't seem to help...

I've been on Eclipse since it was first ported and I have never had any data issues on 4G/3G or wifi. But I've only connected to 2 or 3 wifi networks so I could just be lucky there. 4G/3G connectivity is perfect.

Yea, I really do have to check Eclipse out. The only thing holding me back is that I'm getting (what I consider) stupid-good battery life with AOKP. Plus, I just did a factory reset on ICS to fix notifications, which means I just set everything back up
Have you spent any time on Wifi using the stock ROM? I'm lucky to get half an hour of Wifi connectivity before it just dies (but still pretends to be connected). No problem with wireless tethering (AOKP or stock). Sometimes I am convinced they don't actually test these things before pushing them out...

I never had any problem with stock either. I would run it on wifi all day at home on a Saturday and never had any drops. I just set up a new router last running dd-wrt so we will see how that goes.
You should definitely check out Eclipse. You lose a few of the ICS goodies but it's totally worth it in my opinion not to have to worry about data dropping out. Battery life has been phenomenal for me on Eclipse. I've been getting through a whole day with 40% - 50% battery left when I finally plug it in a night.
Just backup up your current ROM in safestrap that way, if you don't like Eclipse, you can just restore your backup and your back on AOKP with everything just as you left it!

I've used AOKP for over a week and I don't recall having wifi issues. Which build were you on? I used nightly 29/4. Now I'm back to stock because of BT and Camera. Other than that I had no issues.

I haven't really tweaked it or anything. No undervolting/underclocking or anything like that. I have the 4G toggle installed and switch 4G off when I'm sitting at my desk at work and I'm connected to wifi when I get home in the evening. I don't do anything special other than that. I am still running version 1.3.7 as a couple of people have reported that 1.3.8 broke auto capitalization and not having that would drive me nuts.

Guess I wasn't clear enough. Both on AOKP 29/4 and stock 219 I encountered no WiFi issues. And I use it a lot. I have to because when I switch to 3G for faster internet I loose audio (GSM 3G not working yet). So what I mean to say is, not sure what your problem with WiFi is or where it's coming from. I ran AOKP for at least a week. And I've been running 219 since I got my phone (except for that specific week that is). Not once has WiFi stopped working or glitched for that matter.

[Q] WiFi Reception Issues, Nook HD+, Regardless of ROM

Hey guys. I have made a couple posts about WiFi issues in other threads, such as the CM12 development thread, and I started a thread about my WiFi issues in CM12, but haven’t gotten feedback. Anyways, I now know my WiFi woes go beyond just CM12, so I’m not trying to duplicate threads, but rather I’m making a general thread about this issue as I am desperate for help.
Some time back I started having very poor WiFi reception on my Nook HD+. What I attributed it to at the time was installing CM12. However, it’s possible this started happening prior to CM12 when I was on SlimKat or CM11. I have done some more extensive testing on this and would like to give you guys the run-down and see if you have any ideas.
For the first 1+ year I had this tablet, I ran CM10.2.1 without any issues at all, and although the WiFi reception was a little bit weaker than my other devices, it was never weak enough to cause any issues. At some point this past fall I tried out some KitKat builds, CM11 and SlimKat. I had trouble with the stability of those builds, and I can’t recall if my WiFi reception was good or bad on those, but I think it was okay. Because of the stability issues on those ROMs, when CM12 came out I hopped on that to see if it was going to be better.
My WiFi reception on CM12 was very poor. Only sometimes could I stream my video and even then it would cut off after a few minutes. I figured CM12 was the issue so I rolled back to the ‘Jamus28’ ‘Unofficial CM10.2.1 Stable w/ TabletUI + ArchiDroid Optimizations’, since CM10.2.1 ran great for me for so long. I figured that although I wouldn't be running the latest and greatest (Lollipop), at least I would have my stability and more importantly, my WiFi stability back. Apparently I was mistaken.
I am still having WiFi reception issues regardless of which ROM I am on. I have tested at areas around my apartment on the different ROMs. I’ve done most of the testing on the CM10.2.1. The WiFi signal fluctuates greatly, mostly at very very low speeds (using Speedtest app, 1-2 Mbps in some areas, but never gets above 8 or so even right next to the router). On my other devices I get 20-30 Mbps. I've had similar troubles now at my church on their network, which used to have a great connection for me, so I don't feel it's specific to my network.
I have done a ‘hard factory reset’ of my router and set it up from scratch. Last night, I couldn't even start a stream up at all. All of my ROM flashes are always clean flashes. Part of what I’m wondering is – is there something that could be sticking in my tablet files, despite doing clean flashes, that could be causing these issues? Is there any universal command or file between the different ROMs I can check on? Do I need to try a complete and utter wipe of my Internal Storage and start from scratch? Or do you think I just have a device that the hardware has gone bad on? The main apps I stream and thus have had trouble with are WatchESPN and Netflix. I've also had the troubles with YouTube.
Any input, suggestions, or tips are greatly appreciated! Please let me know if I can provide any other information to help troubleshoot. Thanks in advance.

Have you installed a WiFi Analyzer? It can be very helpful for finding both sweet spots and trouble spots.
WiFi can be a fickle beast. Interference can come from a myriad of sources. If you're sure its your HD+, it could even come down to how you hold it. Do you have big,wet hands?

As you have found out it is hard to differentiate between hardware and software but my "guess" would be software. My thinking is signal strength is not your problem as distance makes very little difference. My suggestion, and I'm sure you have thought of this, would be to go back to stock (Leapinlar has great info and instructions) and move forward into CM 10.1 or CM 10.2. You can still download the official stable from the CM site. If going back to completely stock does not help then moving on to a different tablet is the option.

Kokercey just reminded me that I once had WiFi problems with my old tablet (BNTV250). I used WiFi Fixer from the Play Store. I recall that it solved the problem, though I don't recall what exactly the problem was. Anyway, it can't hurt. And it's a lot less traumatic than restoring to stock and starting over. But that would be my next step.

Thank you both for the suggestions. I will check out that WiFi fixer when I am at home.
I had thought about and read about the benefits of going back to stock. My curiosity is, does full-wiping and going to stock OS and then back to CM have an advantage over a complete Internal Storage wipe and then going back to CM?

One of the advantages of going back to stock and wiping instead of just wiping is going to stock also resets your bootdata and recovery partitions and wiping does not. That may not make a difference in your issues, but who knows.

Thanks guys. I tried the WiFi Fixer, but it seems more geared towards issues connecting to a network. I seem to connect okay.
One clue I forgot to mention is that when I use the speedtest app, my upload speeds are faster than my download speeds 98% of the time. Usually 5-7 Mbps compared with the dismal download speeds of ~1-3 Mbps.
@leapinlar, to go back to stock, I would reference item #6 in your CWM Root Tools thread? Flash the older recovery, full wipe, and flash the stock zip? Which stock zip do you recommend for just the reason of cleaning things up? Can I use the rooted zips? Whichever one makes it easiest to get back to a newer recovery and CM is obviously what I'd be looking for.
Thank you all for the help.

Yes, item 6. The newest plain stock, not the rooted one. And just use the older bootable CWM SD to put the cm10s on. Don't bother with putting recovery on internal until you are ready to put the newer one on for CM11, if you get that far.

The CWM SD should boot on its own after inserting it. If it does not then you need to remake it. After booting to the CWM SD do a factory reset with the CWM. That is the only wiping necessary. It does not remove the internal TWRP. The next step does that as part of flashing the stock zip. And yes boot to stock and set it up to test your wifi issues before moving on to CM.

Okay. I did the following:
- Made older bootable CWM card
- Booted to the bootable card CWM recovery
- Performed factory reset in CWM
- Flashed stock unrooted 2.2.0 zip
- Booted to stock and activated into the tablet through my WiFi network.
I've done a little testing running in the stock OS. The WiFi speeds seem to be almost identical to before this exercise (via the Speedtest app). The one difference I am noticing is in the usage of the WatchESPN app. Beforehand, a stream would start at a decent resolution (or not start at all) and then the stream would cut out and not reconnect, presumably when the signal fluctuated too low. Now on the stock OS, it is staying connected, but at a very very low resolution. So it almost seems to be more stable but a really low quality.
I don't remember exactly what the speeds used to be in the tablet's good days, because I never had a reason to study any speed tests. All I know is that anywhere around my apartment it would stream all of these apps at HD resolution with no problems. This is a bummer. Maybe it's just hardware gone bad.

It sounds more like a router change if it is the same on both ROMs. Have you done anything different lately. Even connecting some other new device to the router. Other users have had issues when two devices interfere with each other. Like two HD+s on the same router.

Interesting. I did get a new HP computer in December, which come to think of it could be when these problems started, but I can't say for sure. It runs on the same 2.4 GHz band that the Nook HD+ runs on. Some time before that my wife and I both changed phones. We almost always have the phones on my 5 GHz band. Other than that I have a laptop and Kindle Fire that we've had for a very long time.
Last weekend I did a factory reset of the router due to issues I was having with my phone connecting on Lollipop. I set it back up the same as it was prior. After doing the reset my phone was able to connect again. As noted above, it runs on the 5 GHz. Prior to last weekend the router had been the same for quite some time, certainly well before the tablet WiFi issue.
Perhaps try some testing with the new laptop shut down?
Edit: I did get a new router some time back, but I feel it was surely before these troubles, maybe last summer or so. Let's say it wasn't... how would I test this?

To eliminate potential interference from other devices temporarily disconnect everything from the router except the Nook. Bluetooth could also be an issue. It runs on the 2.4GHz band too. As I remember the earlier issue was when an HD+ and an HD both connected the HD+ (and other devices) slowed way down. There was a software problem with the HD which got fixed eventually.

Your quickest path is to simply turn them all off and test only with what's needed for the nook, which is wifi router/modem and the nook. Unplug the house phones, turn off computers, forget the wifi on the mobiles/tablets, airplane mode, or similar. etc.
One other thing I will point out is that testing max wifi speed over internet isn't the best idea as the results are less guaranteed.. The internet is out of your hands and devices are recognized and delt with on that end as well. Using btsync (http://www.getsync.com/ , https://play.google.com/store/apps/details?id=com.bittorrent.sync&hl=en) and transferring locally a large file (few hunderd MBs or so) from your dektop/laptop to the device though the wifi router/modem (the desktop/laptop should be wired to the router for troubleshooting here) will be able to max out the wifi connection and it shows the transfer speed. Unfortunately, simple ways such es file explorer or similar cannot do so. Transferring small files though btsync also shouldn't max it out as that creates a bottleneck.
The best these things can do is just over 4MBps.

Okay guys, thank you for the help, I do appreciate it. I did a little more testing. I turned off everything I have and just ran the Nook on the modem and router. Unfortunately I didn't notice an improvement in the speeds doing my poor-mans tests (speedtest app and streaming). Similar to yesterday I am able to stream a decent-to-good quality in the immediate proximity of the router, but a low quality further away. I then whipped up the WiFi Analyzer again and decided to try a different channel, but I am still having similar results.
I have not tried the Sync app yet, but thank you for that suggestion, perhaps I will give it a try. Is 4 MBps really all these devices can do? That sure seems low, but I guess I don't know what is typical for a tablet...
I would like to point out clearly that I am in an apartment building. There are a LOT of surrounding networks and devices. However, I've been here for more than two years now and it wasn't an issue prior to these last however many months. Is it possible I have a new neighbor with some new device(s) that are causing additional interference, perhaps?
A side question I have, and maybe it should go in a new thread, is that I've tried a few times to bluetooth tether the Nook to my phone and use the phone's WiFi for the Nook, but when I get to the step of actually selecting to use the phone for WiFi, the Nook wouldn't allow me to select/activate. I would just press and nothing would happen. This was happening on CM; I haven't tried today as I still have it on the Stock OS. Any idea why that wouldn't work on CM?

With wifi analyzer if your wifi is -30 your in great shape with signal strength which one less bar may occur in the -50 range. And if it shows your wifi is on a good channel then its not going to do much for you.

It is for the nooks. 65 link speed is absolute max.

I assume you have a mimo router (multiple antennas) and dual band as well in which case the nooks can't take advantage of that and interference could be more of an issue. But, if you have a cheap end HP laptop it may have the same basic wifi as the nooks - if you look at the connection info in the nook wifi settings and the connection info on the HP networking and they both show 65 link speed that would help confirm the nook is indeed having a problem with something (ignoring any possible differences between internal antenna design). (It looks like HP laptops MSRP above $1k get various combinations of dual band, dual antenna, ac wifi.)

I will check this evening what type of signal strength it was. It is a low end HP laptop and it only runs the 2.4 GHz band so it sounds like what you're talking about. I can check on the device info this evening. However, I had it off yesterday when testing around again and I don't think I noticed much of a difference. Last night I watched a little more streaming and it's possible it was slightly better quality for longer periods, but I can't say for sure.

Hey guys, I had some very busy weeks of work and then a vacation and then some more busyness. I haven't had any improvement in the tablet WiFi in that time. I did some testing today using the BT Sync software. Let me note a few more things first:
- I checked the Link Speed on my Nook HD+ and it mostly read 54 or 72 mbps. I never saw it at 65. I actually saw it go down to 1 a few times but then back to 54 or 72.
- I checked the Link Speed on my HP Laptop and it read 72 mbps, again I never saw 65; it stays steady at 72.
I've done some more using of the tablet around the HP laptop and it doesn't seem to have an effect that I can tell whether the HP is off or on.
FYI I have a Netgear N300 router.
My WiFi analyzer app shows that with my Nook literally within one foot of my router my signal strength gets no stronger than -50. Nowhere near -30 ever. In my further rooms from the router it drops to -60 to -70.
I did the testing using BT Sync you recommended. I connected my other laptop directly to the router and disabled it's wireless as well as the wireless on the HP laptop. I installed Sync on both the laptop and my Nook. I transferred (actually it's still attempting to transfer) a folder with several files, the main one being around 200 megs which it has been chugging away on. With all the other devices off this transfer topped out around 350 KB/s. More consistently it has been around 200 - 250 KB/s.
Edit: Let me know if you think I'm using the Sync app incorrectly to have that slow of speeds. However it doesn't seem far fetched to me based on my performance I have at times (browsing, app installs, etc.)
I hope this provides some more clues for you guys, I'll add a post if I think of anything else. I appreciate all continuing suggestions. Thank you for your help thus far.
