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.

[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.

Wi-Fi poblem in JB ROMS

After the wifi fix ( thanks to all devs who worked hard for that ) I am able to connect to my wifi.
But the problem is, I am not able to access my internet. The problem is the same for all JB ROMS(CM 10, miui v5). All I get is short bursts of access to internet during which webpage loads for a bit and just sticks there. Can't access the playstore too. It just gets stuck at signing in.
My wi-fi is good as I am using the same on my laptop.
Can't seem to figure out what the problem is and am sadly stuck on ICS.
Any help would be great...

I don't have this problem ... so its just with your phone try to reflash the ROM

It's just you. Noone else has that problem.

That's what confuses me...How come is it only me having this problem..
I have tried flashing the ROM for 4-5 times now but each time it's the same...
Have tried doing complete wipe, with and without wiping /system, tried both prometheus and NOPE kernels but the problem persists.
And its the same for cm10 and MIUI v5...haven't tried any other JB based ROMS.
Maybe i shall try to turn off security in my wifi..(can that by any chance be causing it??)

Tunring off wifi security can only cause people freeloading on your wifi. I dont know about the problem.

You could turn off password authentication and filter by MAC address, just to be safe and be able to test at the same time. Although, I had no problems on connecting to secure networks. There is an authentication problem on reconnect, though.

Finally solved..
Got my wi-fi to work finally....
The problem apparently was with encryption....got an idea from this HOX thread
http://forum.xda-developers.com/showthread.php?t=1989203
I earlier used to have a AES+TKIP encryption with WPA-PSK authentication....changing network authentication mode to OPEN made it work instantly.
But open connection = freeloaders...so tried a combination of WPA-PSK and TKIP and it worked too...haven't checked it with AES...
Finally wi-fi is working...
Thanks to everyone who tried to help out....i really appreciate it...

Further the wifi now disconnects only if no wifi related task is continuing and the phones locks up.
If a download is going on, it continues even after phone gets locked.
Just thought I should share that...
EDIT: airplane mode trick + wifi keep alive app (kudos to webhijacker for finding it out) does solve the Wi-fi issues..

See this thread for the fix

And for the authinticating problem you can solve it by turning on airplane mod then turning off then tada

bizare wifi behavior

well, my wifi is acting wierd... reception is good and it doesn't disconnect too often, theres just this little anoying thing!
everytime roughly 3-4 days after i flash a new rom my wifi simply refuses to connect to network, and not a specific one, any network at all!
and it stays like this for a couple of hours and then all of a sudden it picks up a a networks and it works fine for a while, untill i happens again...
i've tried restarting and taking out the battery and turning the wifi off for a while, nothing seems to help, he just decides on his own when he is whilling to connect again....
if i flash a brand new rom the problem disapear for a few days but then it comes back... i'm assuming it has to do with some sort of a cache that is filling up with loads of crap and ruining the wifi activity but i tried googling for this and found nothing..
ideas anyone? (btw this happens on all roms: stock, existenz, beanstalker etc...)

its a hardware problem and not so uncommon look here
http://forum.xda-developers.com/showthread.php?t=2531711
if you can take it to a customer support and if you cant sell it and again if you cant, then just get along with no wifi/bluetooth/NFC check all of them you should have problem with them too

absolutly not related, my NFC and bluetooth works just fine, i don't need to press hard anywhere...
and my wifi works just fine after a fresh rom install... so it's defenetly a software problem...

to me that sounds like the start of it because mine was the same at the first few days flashing a new rom or something would help alot but then i just found out the only thing that was helping it to get fixed was the heat from the device not the rom, but it doesnt hurt to play around with it a little so go ahead and try some other roms or repairs.
you see good reception for wifi
you try to connect
at the authorizing or connecting you will see only one point of signal and connection would kinda like disappear.
this is how it was for me but at the first days it was random it was connected good and ready, when i would left the phone in stand by after a few minutes it would DC, so i thought its kind of a sleep mode malfunction or something but after a few days almost 1-2 weeks it turned out to be hardware problem like ohers so if you see any symptom like that start looking for service centers.
but i hope it would be a software problem for you, so good luck.

Well, once he connects he stays on for days, no problem there... Just sometikes he refuses to connect... Pressing the nfc button doesnt help...

What Wi-Fi channel is your network on and have you tried 5GHz?

Didn't look into those things, but it happens with all networks except ones without passwords
Sent from my C6903 using Tapatalk

Have you tried deleting wpa_supplicant.conf in data/misc/wifi and reconnecting to the network? (this will delete all saved passwords and settings for known wi-fi networks) also try to disable Auto IP in advanced wi-fi settings

Well the phone is qith my sister now, I got a new z1 so far wifi worka for her, it stoppes for a few hours yestarday but came back, I might try to flash. 310 and see if it works better with it. And the Wapa_sup sounds like a good idea. Btw z1 is also jittering some with wifi, it's a global Sony problem...

temp solution?
Well, it is probably a hardware problem. I have had the same problem, everything looks fine, but you can't connect to any network.
So, searched, reinstalled, etcétera, nothing worked. Untill I read a crazy solution link://talk.sonymobile.com/t5/Xperia-Z-ZL-ZR/xperia-zr-wifi-association-rejected/td-p/516275/page/4
and found out that if you put pressure on the back of your pone right at the NFC chip, with a finger or so, the Wifi will come alive again.
Personally I had to hit my pone's back at that exact spot with my finger (for not damaging it with excesive force) a few times, but then suddenly it worked.
So, I am convinced it's a hardware problem. Hope it works for other people too.

WiFi disconnects constantly

It happens mostly when the screen is off (even though I have the always on setting enabled) but also when using the phone normaly. Suddenly I get a toast that I was connected to my WiFi. I've also checked the router logs an I see that the honor 5c is constantly disconnecting and reconnecting. Does anybody else have this problem? I'm on latest emui 4.1.2 without root or any other mod. I played with different channels and frequencies but that didn't help at all. Any ideas? I think it has to do with the battery optimization settings of marshmallow but even on the performance setting the WiFi connectivity just drops.

Whoever finds this will be my hero

In the wifi settings, just check that, "Keep Wi-Fi on during sleep" is set to always or not. If not then set it to always.
Edit : Sry i haven't read ur post properly. Is this the problem from the starting? Coz i don't have this issue.

I think I noticed this problem since the beginning but after flashing the latest 4.1.2 it got worse. Skype and WhatsApp calls get disconnected while screen is off (after 15 seconds or so).

The problem was with the original Rom and the reason why I flashed the latest.

Exactly the same issue.

Hello,
I have exactly the same issue. I checked also dhcp mode in the developer tools.
Did you found a way to solve it ?

Changing the router solved the problem.
