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!
http://code.google.com/p/cyanogenmod/issues/detail?id=3314

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.
http://code.google.com/p/cyanogenmod/issues/detail?id=3314
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.

[9001][SOLVED] WiFi issue : keeps randomly disconnecting

Hi
Like in the title : The wifi in my S+ keeps randomly disconnecting, on various roms (starting from branded play 2.3.4 rom, then on 2.3.5, and now on 2.3.6)
What seems to be the problem ? is it hardware fault ?
I read, in few other threads, that other people, had in some kind of way a similiar problem...
What do You think ? Please SHARE

try to assign staitc ip............it happened in i9003 too

download a root explorer, go to data/misc/wifi/wpa_supplicant.conf and set: update_config to 0 and priority to 1, it doesn't solve the problem but it gets a little better

i had the same problem i did 2 things 1 was after flashing i did a factory data reset and erased SD card (make sure to backup anything you need) and i also went into my Belkin 600N and set DHCP Lease from Forever to 2days.
ive not dropped wifi since and i had it with 4 diffrent ROMs im now using XXKPS 2.3.6

I've set static ip on my phone, switched DHCP lease setting to 2 days, and now testing...
Thanks Guys much love

Here comes super mega answer, which is worth finding Thank You button -
1.) Open dialer and enter *#*#526#*#*
2.) Come back and say that your wifi works without any issues.

i guess he means 528 instead of 526. *#*#528#*#* is the wifi test mode which loads the wifi drivers automatically.

Yeah there are plenty of those codes actually.
for example:
*#*#7780#*#* factory reset
*2767*3855# factory format (everything wiped, also the internal sd card)
*#*#1575#*#* gps test
*#*#1234#*#* pda phone version
*#*#1111#*#* fta sw version
*#0*# lcd test (cool one )
*#*#2664#*#* touchscreen test
they should work on every android device. try google to find more

Thanks mate

So after the tips from Sakindia and BackDaws, when i changed the phones ip to static, and changed the routers DHCP settings, i have no more problem with the wifi connection.
Thanks again guys
I hope, that this thread will be helpfull fo other S+ users

Change title to "SOLVED"

If it is set to static ip and you changed dhcp settings it is only solution for your home network, not anywhere in public, right?

This was exactly the cure for the problem, I can also confirm it. I tried several things, such as exchanging config files between several ROMs, what a waste of time
But I'm still wondering why 2.3.4-2.3.6 can not work with forever leasing time... It's bad.
p.s.: for me no static IP needed for proper work
Thanks for sharing this BackDaws!

[Q] Do have the same problem? (wi-fi)

Hello.
I've tryed many ROMs that are here in xda: Froyobread, GingerDX, GingerXperia, kuyaDROID, xGin, etc... And now I am using Stornmix with stock kernel.
But in all this ROMs I've had always the same problem: wi-fi.
My wi-fi connection works good during 1 or 2 minutes. Then it stops working and I can't use the browser nor the market or other app that uses internet connection.
When I turn off and on again the Wi-fi, the internet connection comes back good, but the same happens after few time.
I even tryed 1 wi-fi fix that i've found here, but didn't solve my problem.
Have you guys experienced this problem too?
Any clue how to solve it?

It is already that way.
Always have been.

Delete the remembered connections.Sometimes too much of them cause problems.

There's a compatibility issue with WPA-AES encryption. It's been discussed here and somewhere else (official SE forum i think). Not much to do about it...

Scratch the "AES" and make it "EAP" ...
IF AES would be a problem I think no one of us could connect to their access points as WPA/2 actually uses AES for encryption ...

I had a similar problem with GDX back in the days of v012 onwards. The WiFi connection wouldn't completely die but only go through a disconnect/reconnect loop every 2-5 minutes (unless I used "Wifi Static" to set a static IP configuration for my access point).
I solved the "disconnect/reconnect loop while using DHCP" problem by switching to another WiFi channel (my Access Point automatically determined channel 1 to be the best choice ... I later on switched to channel 11 and the problems fixed itself) - sounds weird, but worked.
You may give it a try.
On the other hand we already had weird WiFi problems which really didn't go away unless one flashed back to stock (where the WiFi suddenly worked flawlessly again) and changed over to the custom ROM again from there.

Thank you for your help, I'll try that and see if it improves my wi-fi.
And yes, as I can remember, it worked nice with the stock rom.

[Q] why does wifi always die in DjangoManoucheX?

Okay guys I've got a constant problem with DMX, not just with this version, but I start to get tired of it. So after a day or two of flashing, wifi starts to stuck at "Obtaining IP address", and does not connect at all after that. As I said it's not only with this version (I'm on 1.6.5), I have also tried different kernels, etc, but it's still the same. I don't want to always reflash, but I'd also stick with this ROM as I really like it. This problem does not come up on CM-based ROMs at all. Thanks for any tips.
Btw I've also tried static/dynamic IP settings, I've changed a router (not because of this), reseted it many times, so not that I didn't try anything at all.

I never had a issue... Have you installed the rom with full wipe?

Of course I did a full wipe, didn't restore any system apps, and as I said it works perfectly for a few days, then bamm! I was playing SongPop, started a game with someone and it stopped when downloading songs.. then I went in wifi options and it showed this IP bug once again. By the way I've just finished reflashing (now without full wipe), and it doesn't even connect now. I really like flashing ROM's etc, but not the same one all over again lol.

Finally I could set static IP on my phone, works now, Thread can be closed. If anybody has the same problem (I've read I'm no the only one), then holla at me!

I'm having a wifi issue from the day i have purchased this phone my wifi always go in the sleep mode don't know why no matter which ROM i use it goes to sleep after the screen is locked or after 5-6 sec of no use of phone.
i'm the only one having this prob i guess.. I thing its an hardware issue, not sure, hope some1 could help me out ^_^
Note: i have kept wifi policy sleep never

Problems with wifi is a kernel issue.
Its adviseable to post which kernel is used

Well I wouldn't be sure, as I was using Kowalski kernel and KoB kernel too, both had the same problem, and only on DjangoManoucheX ROM. But it seems to work now with static IP set.
akash.mahadeshwar has his ROM/kernel stated in his signature, too bad I can't help you.

Lol I don't know if its hardware or software issue but changing rom or kernel dosent fixes it :-/

have you tried changing your wifi to static ip?
if not, then go into wifi settings and long press/modify the one you cannot connect to. Go to advanced settings and change from DHCP to Static IP. Run Windows commander (just type 'cmd' in the Start Menu search box), and type 'ipconfig /all'. It will show all the informations you need to type to your device's wifi settings. You can give almost any number to the first IP field (when your IP getaway is, for example 192.168.7.1, you only have to change the last number to any you want to, like 192.168.7.155.. but the best way is to get the IP number your device used before wifi got stucked). If you can't see DNS1 and DNS2 in your ipconfig, then you have to go into your router's settings (in browser), that will show them. If you type everything correctly, then Save button won't be greyed out no more, and voila. Wifi works perfectly for me since then. I hope it helps.

Changing Wi-Fi to static is far from being a solution; at best it's a workaround.
It's probably related to LG code, used to compile the module loaded by kernel.
I'm not sure if the problem you're reporting us exactly this: I have a brief disconnection/reconnection sometimes when I unlock the phone (Wi-Fi suspends policy sets as never), but this it's not annoying me to much because while sleeping it's connected, and the 2-3s after wake-up is not to much.
Do not say "thanks"; just press it under here.

No, my problem was I could not connect to my wifi AT ALL. Couldn't even do it after a full wipe and reflash, so using a static IP is a solution for me, as it works for 3 days by now. It can be related to the stock ROM's code, as CyanogenMod ROMs don't have this problem for me.

Try flashing KoB kernels again, in mine its wifi work correctly

Internet Connection is Enabled(problem)

Hi,
I have an xperia z1 C9603 on android 4.4, recently something happened, I keep getting a message(the time between messages varying from 5 second to approx. 2 mins) in the lower region of the screen saying "Internet Connection is Enabled", I'm constantly connected through wifi at home and via data services otherwise, I'm curious what started to trigger this and feel concerned that it maybe some sort of malware or spyware working in the background which is causing this, also it seems switching off wifi seems to decrease the frequency of the messages. I have not made any change to network settings, my phone is on the stock rom and is not rooted as well. I have scanned it using dr. web anti-virus and kaspersky(which is currently installed) and have not found anything yet.
Any help on this would be highly appreciated.
Thanks! :good:
