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.

GPS problems with lte

When I have a 4g connection my GPS doesn't work. The second it goes into 3g the GPS picks up. Pictures attached are GPS status started in 4g and right after it switched to 3g
Sent from my HTCONE using Tapatalk 2

Wish I had a solution for you, but I've had ridiculously fast lock on times in GPS Status with both 3g and 4g. Only thing I've done is install viperROM and Wolfpack kernel. Can't remember off hand if either of those have had GPS enhancements.
Hope you find a fix.

Installed stock deox rom. Hopefully I will enter lte today to test. Was on sd 1.2

Stock rom worked.. Seems to be a problem with SD 1.2.1 ... Not sure if it effects all roms (don't have LTE at home yet so was testing it while on the road)

Total N00B Question about ViperControl
So I started the emulator and got to the menu...how do I actually access the options? I type the number and push enter but nothing happens. I'm sure it's a dumb dumb question but I'm stuck. Thanks!

Not sure if my situation is related, but on two separate occasions, I also lost GPS all together. I wasn't paying attention to 3G/4G, but like yours, it was also 0/0 satellites; however, if I were to restart the app, the satellites came back. I let my phone try to find signal for five minutes or so the first time this occurred to no avail. Could have been just fluke occurrences, but we'll see if it happens a third time.
Question: Does re-routing take a little longer than usual for anyone else? I noticed that when I made a different turn today, it took a good probably 10 seconds to re-route. Not sure if my phone is just wonky or what, but my GPS has definitely not been up to par.

Viper, been running it since 1.0.3. At the time, I believe my kernel was stock (now running Wolfpack). Haven't had to use GPS for any decently long lengths recently, so I haven't ran into any issues as of now.

Viper is working fine... It was SD that I had the problem with

I haven't had any GPS issues yet with or without 4G on either stock or Viper 1.0.4 w/ stock kernel. For the record, I have Qualcomm's IZat enabled. Not sure if that makes a difference.

Data connection issues

Anyone have any ideas on this? I'm S-OFF and am all up to date (ran the latest RUU). (Was on stock ICS until a week or so ago, when I ran rumrunner).
On some roms, I have pretty severe data connection issues. For example, on ViperOne 3.5, 3g/4g drops out a ton, and is very unstable while tethering. I also notice issues when just using data on the phone, without tethering going. I can have full signal, then the data connection will just drop, and sometimes take several tries to reestablish. Sometimes I get a 'failed to establish wireless data connection' notification briefly until it reconnects. Sometimes it will randomly drop to 1X or the signal bars will flash to empty and back again before crapping out. It's very bizarre.
With the stock rom, I don't have it set up to tether, but I did stress test it a bit with Netflix and some data usage and didn't notice any issues. With CM11, I did tether for a while and it seemed rock solid as well. With the GE 4.4 rom, same issue with data dropping. I also did NOT notice this issue at all before unlocking/s-off.
It really seems to be a software issue, but I'm at a loss here. I really have been liking ViperOne aside from this issue, and would love advice on getting my data connection stable.

I have always had these issues too. Very annoying. I don't know if it was good before I s-offed and unlocked because that was the first thing I did when I got the phone. I cant get through a showtime or Netflix TV epside without it disconnecting at least 3 times during the 45 minute show. Matter of fact it even does it on WiFi. I don't tether so never noticed that situation. Every Rom I have used I had this problem. Just a little note I have not tried an ruu yet.

It's making me seriously consider grabbing a Nexus 5 or something (but then I'd miss the IR blaster, which comes in handy at bars, haha). But, I'm really thinking (at least for me) that it's some sort of software issue. Rage One and CM11 both seem rock solid, I flashed to both of those and streamed Netflix over the tether for a good 20+ minutes with no problem. Restore ViperOne and repeat the same thing, and connection drops several times within the first few minutes.

I've never gotten data to work for me consistently on cm10.1 or 10.2, haven't tried 11 yet.

I noticed this on the newest radio.. I switch back to the previous radio and my data drops (specifically while tethered) went down a lot.

CM 11 Albinoman nightlies 21/01/2014 MMS not working

Hello.
I recently dusted off my Australian Velocity after the Nexus 5 went for a swim at the beach. I have S-off, rooted and installed the albinoman ROM.
There are a couple of issues I have noticed so far.
The 4g connection is patchy at best. Not very stable at all but I can live with that.
The battery indicator is acting strangely it stays in 100% for ages but then it starts going down very quickly until it gets to 14% where it stays for a long time but once it gets past that it just goes to full discharge very fast.
I am having the same issue that many other guys and my MMS capabilities are not working. The phone just stays sending or retrying but messages never leave.
Any suggestions about what to do? I have wiped and reinstalled the ROM a few times and it makes no difference.
On the other hand I love the overclocking capabilities makes the phone feel a bit more responsive.
Thanks and keep up the good work

As for the 4G connection, once you've accumulated 10 posts you should mention this in the CM 11 ROM thread and ask if the APN needs to be any different than normal (or if the mod changes the APN). The battery issue should get fixed if you let it fully charge and fully discharge about 3 times. The MMS capabilities is a known issue; try the specific nightlies that albinoman recommended to fix the MMS issue. New nightlies might break previous fixes and stuff.

Same Issue
I'm having the same issue here for AT&T HTC Vivid, none of my MMS were sent, nor have I received any. It's really essential for me cuz of my group, clubs have MMS and inorder for me to get those notifications I need MMS.
Calls are okay, but there are times where there's no sound on the other caller, so to fix that I end call and call again, which fixes it.
One final issue I've been having since Jellybean and Kitkat is the proximity for when calls, it does not respond. So i have to turn on Settings>Accessibility>Power button to end a call, because the phone's screen stays black during call, and 10-30 seconds after call. Camera is okay too, but doesn;t function well in video recording in apps like Snapchat and Instagram.
Overall, it's a great ROM by albinoman, I wish the Sweep2Wake is soon embedded, that's really great and wayyy better than the power button.

Thank you very much.
I tried Albinoman suggested rom and I still have issues with MMS.
The battery indicator is normalising as you said it would.
I know about the 10 posts count but it is hard for me to just write a post for the sake of getting the count up.

Yeah, I hear ya, I've been there before too. The posts will generally come easily and quickly posting to q&a and general, so you're on the right track

I'm also in Aus.
Been running CM versions now for over a year.
The new CM11 has been trouble free, with one quirky problem. I manually set my network preference to 2G at one desperate battery extending moment.
Now i can't find how to select "4G"??? When i use the preferred network type i only have 2 or 3G as options.
When i search for available networks i get an "error"

Well, I just did what you did, and rebooting does not fix it, nor does clearing the data of various apps installed. I'll post this to the CM11 thread and see if any answers or ideas are brought to light.

Many thanks, i saw the post!
Yeah I tried clearing everything. Did a manual reinstall of the APNs using a number of different configs.
Did the wipes ....... did a little dance .... pulled the battery and sim ...... sacrificed a small packet of tofu (no goats, i like goats) The gods of mobility have still not smiled my way.
Wont find networks when i do a search yet am nicely connected, can make calls etc etc.
thanks for trying. If i get no joy will reflash a nightlie and see if it resets?!

Yeah, although wiping the caches didn't do the trick, reflashing a nightly (along with wiping data, cache, and dalvik-cache) should take care of the problem. If you are really attached to your app settings, look into titanium backup for backing up your apps along with their data; it's also the way I save my WiFi passwords.

Hi, tried the dialer solution and no joy.
Installed INtelli3G but it needs the xposed framework which simply won't install. Have tweaked instal options appropriately so it should???

Fixed
Many thanks rignfool
I installed xposed and Intelli3g and with a bit of mucking around now have 4g back!
Seems to work, have 4g 4 bars!
My initial attempts to force lte caused me to have no coverage (I was at work in North SYd so good LTE normally).
Using the "use all" option in Intelli3g, a reboot and swapping around towers was the trick for me.
Thanks again

Awesome! Do you want to make a step by step instruction set on how to fix that? I would like to know, and I'm sure a newbie who runs into the save problem would really appreciate it.

WiFi stops working

I noticed that WiFi stops working on my new G4 pretty often. The WiFi icon is on, and the connection is "up", but the data transmission stops working. I see the top arrow blink (is that transmit?) but the bottom arrow doesn't come up anymore. Trying to do anything fails and times out.
To fix, turning the WiFi off and back on makes it all work again.
Anyone else experience this problem? I know @jonathan3579 reports the same issue.
I am connected to 5 Ghz using an Asus RT-N66 running Merlin firmware. I have no issues with any of my other devices.

Using the "Switch to mobile data" option helps a bit by falling back on LTE when the WiFi stops working.

Are you having this issue everywhere you go or just one specific place?

I had not noticed it at work, but I only got on the WiFi yesterday for a little bit. This morning it failed on me, so, that's two for two. Haven't used it in many places.
The hotspot works great though. I tether an iPod Touch in my car automatically whenever I drive and I haven't noticed any issues there.

I just noticed this today happening to me too. =(.
Pretty great phone otherwise! Also connected 5ghz to a RT-AC68U (the T-Mobile cellspot), flashed with an older Merlin firmware.
Had to reboot to get it to behave again.

Me too
I've been having this issue too. I've noticed that I lose data and WiFi calling simultaneously. I thought it was my router because we were having issues with the router dropping phones and laptop, but now with a new router it is only my phone that is having a problem.

Running DNSet has definitely helped with keeping the data flowing, and I appreciate that.
WiFi calling is still dropping. When I look in the settings it says "enabling" and just hangs.

This issue appears to be due to the 5ghz radio. I am not sure if it is software or hardware, but if you connect to the 2.4ghz band, the issue will go away.

Lollipop on the G4 maybe, but I have used a Nexus 6, a Moto X and a Dell Venue 7840, all running Lollipop, without issues. The G4 is the only one that has this issue. I never tested my old G3 on this network with Lollipop, I sold it before the update rolled out.

I switched to 2.4 ghz and WiFi calling appears to be staying connected. My provider is Oceanic Time Warner and my router is T-Mobile cell spot.
Fingers crossed and thanks for all the help.

Did these wifi problems start after root?

Mine were happening before root, I think. I switched to T-Mobile cell spot router right before I rooted because my old router was regularly dropping connections, and I have been paying attention more since I rooted. I am also caring for 11 month old twins, so things are kind of a blur. What I am saying is I might not be the most reliable source. I can say that switching from 5ghz to 2.4ghz seems to have solved my WiFi issue.
