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.
im having problems with my 3g on my phone its a samsung galaxy s 2 gt i9100 and version 2.3.3
it keeps turning on and of randomly for no reason some times it just goes of and other times it actually deactivates itself. ive removed juice defender which i thought was the cause but its still switching on and of randomly somtimes it will last for a hour or so other times it wil go on and of every 5 mins.
sometimes i can simply switch the data mode on and of and that works but most times i have to reboot the phone and everytime i reboot it the internet is back on.
what could be causing this its driving me made as i use my phone as a router most of the time. i know its not the network im on because it happens in every country i go to on a new sim.
is there a simple solution is it a android fault or samsung fault?
anyone have a solution to this as i really like my samsung phone but this problem is really annoying.

anybody else get this problem with a samsung or android phone ?
I don't own a 9100 but a 9001 (SGS Plus). The 2.3.3 firmware for my device gave me the exact same issue. I solved it by updating to 2.3.6. But you would need to ask someone who is more familiar with the S2 which ROM ist best as I don't know those.

thanks for the reply now how easy is it to update the phone it says there is no update avalibile when i try to check for updates.
How easy is it to do this rom thing and flashing id need a step by step guide id rather just be able to update it with the click of one button.
i assume you havn't rooted/flashed before? if not, either get into a decent wifi area and update your phone through the settings (that worked for my friends galaxy ace) or see if theres an update through samsungs own software "Kies"
personally i think the 3g issue seems to fall on samsungs side of things but i could be wrong,
no i havent rooted or flashed before. When i try to update in the phone info check for updates it says there is none im currently in the uae is the update done by the network or by samsung. Ive never used kies either. Ill have a look at it i thought kies was just another form of wifi.
Hi all,
Since about 1 year i'm a happy owner of the Galaxy Note. As the stock rom was quite crappy (eating battery like crazy) I decided to swap it with a CM10.0 flavor (Cookies & Cream).
Well, installing the ROM went fine and the phone worked great, except one thing.
Since the beginning that i'm using custom roms on this phone, i'm randomly having issues with the telephone or 3G signal. As I thought, maybe the ROM is full of bugs, I wiped the phone and installed the official CM10.0 ROM. Unfortunately that solved not my problem. Since a couple weeks ago i updated to CM10.1, and still having this issue.
However, some issues where solved since the last upgrade:
- First ROM (CM10 flavor, Cookies & Cream): randomly dropping the signal, and asking for a SIM pin. Sometimes even a restart was needed
- Second ROM (Official CM10): same as above, but less issues with the SIM, mostly signal related
- Third ROM (Official CM10.1: SIM issue gone, however the phone is sill loosing the data signal + sometimes even the telephone signal (restart needed).
When I loose my signal, something it's just the data connection (3G/H). The strange thing is that most of the time that this happens the data connection or telephone signal restores when I enable/open the screen by using the side/home button. Well, that's very strange as I have no power saving apps or something like that running.
But unfortunately this is not always the solutions. Usually 1x per 2 days I have to reboot the phone in order to bring the signal for telephone + data back alive.
SIM has already been replaced, with no luck. I did install this ROM on another phone (from a friend) as well - which had in the beginning the same issues, however things seems to be become stable (haven't heard him anymore)
I already tried different modems on my phone (XXLSA / XXLSX, currently using XXLSO), but none of them solved this loosing data/telephone signal.
It starts to drive me crazy, as I use this phone for my work too.... being unreachable is quite annoying
Anyone an idea what goes wrong here, or how I can find out why this phone is going nuts?
Nobody that could explain why my phone is having this behavior?

Hello guys,
For the past year or so I am having intermittent problems with my 3g connection. It just loses the connection with the mobile internet without any error messages and the only way to fix this is rebooting the phone. At first it happened every couple months but the intervals between connection losses seems to get shorter. The last few months it was every 10-14 days, now it's every 5 days. Since a reboot seems to fix this I don't think there is a physical defect on my 3g chip but the shortening intervals are somewhat worrying. I checked my APN settings multiple times and I've called my carrier's tech support several times but they too can't seem to find anything wrong with my APN settings. I'm currently using a custom ROM (OmniROM based on Android 4.4.4 with the Stagefright patch included) but this problem existed even in the original ROM so I doubt it's a kernel/driver issue. Is there anyone knowledgeable enough to pinpoint the problem or at least help me in the right direction because it's becoming a bit annoying and I dislike not being able to figure out WHY something happens. ^^"
The issue you have mentioned applied also to my phone, but it appeared for the first time after installing Omni from golden-guy. I haven't observed it on my stock rom. At the very beginning, I was able to mitigate the issue by turning airplane mode on and off. As you mentioned, the issue's frequency was increasing over time, leading to more than one signal lost per day. Airplane mode solution stopped working. I have also tried to kill (and got restarted) rild, as well as radiod - with no luck. Logs (I haven't checked kmesg) revealed nothing. I'm not sure the details of your issue, but I was loosing the whole GSM/WCDMA signal, not only the Internet access. Meanwhile, the system seemd to be looking for a network, draining my battery.
I still hope that the solution was to replace my SIM card with a new one from the operator. After that, about a month ago, the issue happened only once, and airplane mode on and off solved it. It's worth to notice, that turning airplane mode on took quite long time, about 30 seconds.
I'm having GT-I8190, Omni version 4.4.4-20151108, baseband I8190XXAMG (I'm not sure if it is distributed along with the rom, or maybe resides on different partition, and is not updated with the omni rom releases).

Did you check logcat? If you didn't then logcat might show what the problem is. And your problem sounds more severe than mine. I only lose 3g but I can still call and send text messages. A problem with the simcard might be possible but it could also be a physical problem with the simcard slot though I can't say why rebooting or turning airplane mode off and back on would fix that.

I just wanted to confirm that I have similllar issue with 3g data connection. S3 mini with I8190XXAMG4 baseband. Stock ROM used for last few years (without any significant issues with 3g data connections), upgraded to latest CM11 20151017 from maclaw/novafusion. I noticed that there are some glitches with 3g data connections. Sometimes I need to tap few times before connection finally is being established. Funny thing is that I have second s3 mini with the same CM11 20151017 and all is OK.
I tried a lot of another ROMs; fifferent version of CM11, OmniROM (4.4.4 and 5.1.1), CM12.1 - problem remains - issues with 3g data connection. Is there any solution to get rid of this 3g data issue?

Yes, logcat (main, radio, events) revealed nothing but just signal drop to 0%. At that time, I didn't know about kmsg and system logcat buffer, so I haven't checked them.

Just tried this, and it helped. Usually, when something is not working, people try to turn it off and on again.
I always had rare glitches with mobile data connectivity, and turning mobile data off and on again always solved the problem. I think our problems my be hardware related. I suppose my old SIM card could have buggy software, i.e. advertising to support some newer protocol, but actually didn't. After upgrading, the phone tried to use the new advertised protocol, and got confused, or made the SIM confused.
I also know about cases, when SIM card simply died without any reason.
I used Note 2 about two years, flashed different roms and never had troubles, but then my friend used it about 3 months on 5.0.2 custom and got troubles with gsm/wcdma. My next samsung phone become our beloved i8190. Flashed it from stock to 5.0.2 CM, than 5.1.1, after month got first Cellular bugs. Tried another LP and some KK roms, my troubles with baseband became more and more frequently every day, flashed different modems, changed much settings in system.. So I was desided that it's all HW problems, and hated Samsung for such failure. But one day just tried to install Project Noble, and all this troubles gone forever. So it's just drivers, which not optimised for new Android versions. 4.1.2 mixed with old TouchWiz after fresh and clean Lollypop feels horrible, but we can do nothing with it.

But if it's hardware related, wouldn't you think that rebooting our phone or turning airplane mode on and off wouldn't fix it? And did you see in the logcat log if something happened before the signal drop? Sometimes events prior to the signal drop can also tell something about the cause.

Hardware could also have its state, which may get corrupted and reset on reboot.

I am writing this thread to ask if there is a way to fix this bug on cm based roms.
I am running RR rom and it is great but when i reboot my phone, the time and the date are always wrong. I have installed Clocksync app to synchronize but i hate this bug because i must have always internet connection to sync time and date.
Of course there is no bug with stock rom.
Does anyone know hot to fix this? I search everything at the net but i did not find any solution. Could anyone help?
I have seen that if the area in which i am covered by LTE signal, there is no bug and the rtc is always correct...
