Wifi Problems

Hi all
I have a strange bug with wifi and i dont know if its karnel or baseband related.
After the phone is not restarted for 40+ hours i cant turn on wifi connection it says error in setting.
I have to restart the phone so the wifi will work for another 40 hours. I tried it with stock and neoblaze karnel, froyo and leaked ginger roms.
This bug is always there the only thing that i have the same is the baseband 622.
tnx in advance

Sorry to hear you have this issue, I have it as well.
V10d an 725BB (which is supposed to fix this error). I have to restart the phone every 100 hours uf uptime.
Will wait for the GB update if not, it is going back to service.
Regards

I have the v20e leaked and its the same as froyo. I think its a karnel issue and all the stock and modified karnels have the same issue.

Let me guess: The lease time on the networks DHCP-server is 48 hours? If that's the case there's a write-up here: http://code.google.com/p/android/issues/detail?id=11236
Short version: A bug in Android itself; not renewing the lease properly if the DHCP-server doesn't send a server ID. Continues to ask for renewals and rejecting the DHCP-offers, and sooner or later getting kicked off the network for excessive requests. (and a few other things.)

Same here. Doesn't matter what ROM/BB/RIL I'm using. Wifi fails like clockwork after about 70 hours of up-time. I'm surprised this issue isn't more widely reported. Perhaps most people got fed up by the SODs so they simply reboot everyday?
And no, it has nothing to do with DHCP. The hardware just refuses to be switched on past a certain point. And it doesn't seem to matter how many times you've toggled it previously. It's likely to be a driver issue.

Should be easy enough to test. Enter your wifi-settings and choose a static ip-address which is valid, but outside the dhcp-scope of your dhcp-server. If it still keels over at said time, then sure, it has nothing to do with dhcp. If it doesn't... (remember to reboot after choosing a static ip, as one of the consequences of the bug is that the phone keeps using ip-adresses it's no longer authorized to use until the next reboot.)

Its not the dhcp i know that much im an it manager working for internet provider. The wifi does not turn on i cant even search for network. Its says error starting wireless. U cant turn the wifi on untill u reboot the phone.

Fine. I wish you good luck in solving your problem.

Same problem here... V10c.
It's not a problem in my network, my tablet, notebook and last phone (Nokia) never had problems with my home wireless network.
When I try to activate the Wi-Fi I just get the error status, I have to restart the phone to bring things back to normal.
Also, I don't leave the phone Wi-Fi on all the time, I turn on only when I need.

Finally decided I have had enough of this (and this too!) and followed this guide to automatically reboot my P990 daily.
http://blog.homelinux.org/?p=341

Before, I have wifi error randomly (MCR FR17 or 18 maybe), sometimes it can't turned on (error), only reboot can fix it.
But after I use FR19 and now Topogigi, never have that issue anymore.

Ive noticed this error only happens after i recharge my phone. I think im gona flash 0725 baseband and test it.

0725 on my phone, no wifi problems. but dont think it is releated.

I have the same issue but I think I can narrow it down a little, I'm on 0405 BB, will see if it changes after I update to 725 and MoDaCo Gr3.
Anyway here's the deal. I realised the "Wifi error" appears only when you have Wifi turned off for most of the time. It starts after about 30-35 hours of uptime with wifi off. If you have wifi on for most of the time, it will work normally, as soon as you turn it off the "counting" starts. When you reach a total of about 30-35 hours of wifi off, it won't turn on with the dreaded "wifi error" message. After that there are times it does start but rarely. I also noticed that as the "wifi off" time increases it takes longer and longer for the wifi to turn on. After restart it takes about 1-2 seconds. After 15-20 hours of "wifi off" time, it takes 5-6 seconds. Looks like if wifi doesn't start in 10 seconds the OS will automatically declare it an Error. I tried to do a logcat and only thing I got was something about wireless.ko not reachable or smth like that. It's almost like there's a memory leak or smth in the baseband that is triggered only when the wifi is off. Doubt it's something like that but the description itself fits.
It's pretty annoying. I try to keep the wifi active for most of the time but it consumes battery when I'm outside (constant scanning). I would be grateful if someone else could look into this problem cause I doubt it's a hardware issue. I'm updating to Gr3 and BB725 next week so I'll let you know how it goes.

I have the wifi error too and while I used to reboot, I have found another workabout that doesn't require reboot. That is to switch on airplane mode. On wifi. Off airplane. On wifi. Wifi will normally connect after 1 or two such cycles.

Turned off WiFi today so I can test your method. It will take another 24 hours for the "WiFi Error" to appear. Hope this helps although I've already tried Airplane Mode and similar stuff. Unfortunately it doesn't help much if I have Tasker to turn on WiFi.

I tried you solution and it only worked when I first got the "Wifi Error". After some 8 further hours it doesn't help any more. "Wifi Error" started late last night. Airplane switching helped then (but also did multiple On-Off on Wifi). But this morning (I left it on 3G while it was charging just to test further) it didn't help anymore. :/ We'll see if new BB and ROM changes anything.

Same problem with me on every Rom do u guys found any solution? I use viber and after sometime I cannot receive any message or call from viber, whatsapp etc.

[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.

Massive wifi bug on stock Lollipop

Wifi turns off automatically and it's impossible to make it work again without rebooting. Am I the only one with this issue?

I have a variant of this, I've tried with both the .03 and .04 radios, it's the same, so it's not the radio itself:
I lose coverage so I get the wifi icon with the exclamation mark, instead of it reconnecting automatically. Switching wifi off, then back on, allows me to use wifi again.
I'm using the NX5 AOSP ROM, 5.0R6 (LRX21T)
We all get different experiences, but it sounds like the root cause is likely the same.
Give as much information as you can (Android version, radio, which particular ROM, usage), otherwise it's impossible to understand what could be causing the issue.

The same happens on my Nexus 10 (which doesn't have a radio as far as I know) with stock rooted 5.0.

Wi-Fi delayed list...
A very annoying bug that i am facing is when i enable Wi-Fi i have to wait more than two minutes to get the Wi-Fi network list meanwhile i might get messages like "settings are not responding" also none of the new Wi-Fi networks are saved b in to saved network list, so i have to enter wpa keys again and again....

Did you do a clean install or did you just install it over your 4.4?

once you click "flash all.bat" it formats and cleans everything, so I guess I clean flashed it.

I guess I'm just wondering if these are issues are due to not starting a clean slate. I typically try to do a clean wipe of the internal NAND whenever it's a major revision change (4.4 > 5.0).
But if the bugs are persistent for those of you who did a clean install...maybe it's better to hold off for now.

I did a clean flash all as well and have the same issue where WiFi is never turned off. Wtf google. Battery was awesome right before the update

Thanks for the info. I guess I'll hold for now.

as for me, usb tether always turns of itself when i wake/turn the screen on
stock image rooted using CF
wifi works fine

Mine would lose connectivity, meander about for 30 - 60 seconds, and reconnect. I set the WiFi antenna to 2.4Ghz (from Auto) and turned off "Scanning always available" (although I doubt the latter had anything to do with it) and it's been fine ever since. This was on a clean factory install -- no root, no OTA update; pure OEM Lollipop ROM.

Whenever i go to settings > Wifi settings the phone freezes for a couple of seconds and then it crashes. This happens like 70% of the time.
Anyone else having this ?

I dont have any wifi etc problems
Only thing i have noticed so far is the recent apps bug that shows up sometimes
--------------------
Phone: Nexus 4
OS: rooted Lollipop LRX21T
Bootloader: unlocked
stock Recovery

Bluetooth tethering between nexus 4 and nexus 7 breaks every 30 mins or so.
You have to reboot to get it working again.

Decided to take the plunge. Installed lollipop. Am happy to say that I do not have this issue occuring to me though.

yup, wifi issues for me.
Notice it when I get home, my wifi will not connect and when I go to check the settings it has been turned off. So of course I try to turn it on but everything I try does not work, I am unable to get it to turn on. Only a reboot will get wifi working again.
Not happy at all about this. and a couple of other features. Now I'm wishing I never did the update. Google you have taken my expensive smart phone and turned it against me.

It could be a combination of your router and something they've changed in how Lollipop handles networking.

I have the same issue. On my Nexus 4, I just set it to 2.4 GHz only, as 5 GHz has never worked since 4.3. I can only connect if I hold the phone up to the router. On my Nexus 7 where 5GHz actually works well, I like the fact it prefers 5GHz.

Wifi turning on automatically

I haven't found any other threads about this and I couldn't find any option in the settings to turn this off.
I have the UK version of the phone with stock (untouched) image, the latest updates installed and not rooted.
Issue: Every now and then my wifi turns on by itself. I haven't been able to pinpoint if it happens every X minutes or every time something happens. I am using my cell data because the wifi at work is crap so every time it turns on I start to get stuttering on youtube and stuff like that.
Anyone else have this issue? Does anyone know how to fix it?
Thanks in advance for the help.

Maybe try in advanced WiFi settings... It's in the 3 dot menu on WiFi settings page... It's turn WiFi on automatically enabled?
