Wifi Error

So after a search here and through Google I haven't been able to get this fixed. I was running CyanogenMod 5.0.8 without problems, but wanted to try out Chromatic 4.5. After flashing Chromatic, WiFi worked for a few hours, but then it just suddenly stopped working. From the "Power Widget" WiFi just shows the grey bar below it like it's turning on/off, but it's not doing anything. When I click it, it does nothing. If I go to Wireless and Networks from the Menu, WiFi shows "Error" up under it. The only possible solution I've found was for the Droid that said to try flashing the ROM using a GoldCard, but that was with the Droid 2.2 update. I gave it a shot anyways with no success. I tried flashing with and without the GoldCard, and in both scenarios I tried flashing with and without a wipe. I restored my CM backup and WiFi is working again, so it's not a hardware problem (which I didn't think it was in the first place). Any help would be greatly appreciated guys and gals.

Bump, just to get back to the top I'd really like to get this straightened out.

Read and search the posts in development. It is simple to fix that error. Your situation is an incompatible rom. Try using CM6.

Incompatible ROM???? It's a ROM using the CM 6 kernel and WiFi worked initially, so that's out the window. Thanks for the input though.

I have had the same problem since 0825 nightlies (nightly prior to CM6 official). Wifi works on the 0825 nightly but EVERYTHING since I get the wifi error. Logcat reports wifi driver failed to load. I have manually tried starting the driver, but still this damn error. I did flash the TMUS Froyo cm6 remix and that rom my wifi worked perfectly. I have flashed both pershoot and dumfuqs kernels--still the error. I manually pushed all things wlan to my mytouch and still nothing. So, there is no doubt that the error lies in the cm roms (or at least where it is mapping the drivers on our phone). Very frustrating. The fact that there are only a few of us having this problem leads me to believe that it is indeed a hardware issue or we have corrupted memory on our phones.
Anyway, I have given up trying to fix it. If you find a way, please post.
But, try flashing the tmus froyo remix AFTER nandroiding your rom and see if wifi continues to work.

I just reverted back to CM 5.0.8 for the time being. I'll probably try the T-Mobile 2.2 for the 32B since I'm sure someone will port it to the 1.2 once they get their hands on it.

[Q] Wireless-N driver unstable when connect to Win7 AP/connectify?

After i flashed HCDR.Kernel v4.1, the connection drop randomly when my wildfire try connect to Win7 Access Point(Connectify).
However, issue seems to be gone if i revert back to HCDR.Kernel V3.
I wonder if anyone facing same problem. Is there a way to fix this with V4.1 kernel?

Try v4.2. Although that has the issue of the clock speeds being set at 19 - 768 by default. But, if it boots for you, you can use SetCPU or something to change the clock speeds back to normal.
4.2 changed the Wi Fi Driver over 4.1, so, it should fix the issue.
If it still doesn't, some member modified the kernel so that it is stable and with the new Wi Fi driver. That thread should be there somewhere in the Wildfire Android Development Forum.

unfortunately, kernel v4.2 won't work on DK custom for wifi. kernel v3 is unstable even it booted, wildfire reboot occasionally even if cpu set at 518max.
I found the mod kernel with fixing wifi sleep (http://forum.xda-developers.com/showthread.php?t=967746). Yet no luck. Reverting back to original kernel atm.

seems like it is the compatible problem with my connectify host on wifi N mode.
It works fine after it flashed the homemade kernel from HCDR source with N mode disable.
Another issue is the connection drop, should be due wifi sleep issue. It goes away after i use wifi fixer.

Tethering not working

Hi guys,
i'm running cyanogen 7.0.2 on my desire Z and i have a problem : it is impossible for me to do wireless tether. I remember that it was working on my DZ with the original ROM (htc).
Here are the details :
when i try to use the tether in parameters => wireless networks =>acces point , both wifi and usb shows "error" without more details.
when i try to use "wireless tether for root users", the log contains :
activating wifi interface : failed
setting ad-hoc mode : failed
setting essid : failed
setting channel : failed
enabling nat rules : done
enabling ip forward : done
tethering now running : done
I already tried to flash differents kernel and differents radio, but it is still the same ...
any ideas ?
ps : sorry for mistakes.

I am on CM7 Stable, running wi-fi tethering using it on my second phone and my laptop, seems no problems at all. Getting a decent speed of 3M up.
You may want to try reflashing your device, start from scratch, might solve your problem.
Just a note, I had a similar issue before I flashed CM7 on my G2 with different ROM. As soon as Stable was released, flashed it by wiping my phone completely, and here I am... no problems as am typing...

So a full wype of my current cyanogen, and reflash the 7.0.2 may resolve the problem ? i'ell give it a try.

i tried a full wipe, format system and all stuff. It doesn't work. When i try to use stock wifi tether, i have an error on my computer (limited connection), and when i try with wireless teher, same errors as first post... :/

Up !
Still the same problem .... i tried to reflash again, no change. any ideas ?

Here is a little update : after reflashing and restoring a nandroid backup, it looks like that the usb tether works a bit. i can go on google, but after ... it's very slow and i get timeout errors.
The wifi tether still don't work.

are you currently being throttled for excessive data usage? that's the only time i have the problems you're listing with the wifi-hotspot

I have the same problem. It's not the cm7 rom because I've had the same thing happen on different roms. Its not throttling thats bs. I'm still doing research I'm gonna figure it out, any help would greatly help though lol.

had lite'ning 1.4, updated to 6.1, now wifi issues

ok basically i bought the phone second hand with lite'ning 1.4 on it and the wifi worked perfectly ok all the time. Since it was very old i updated it to 6.1. ever since then I have had issues with the wifi. it will connect perfectly fine to the router but i have no connectivity from it, nothing will get any net access at all. This is also not 100% of the time, its MOST of the time but not all, i do have moments where it does work fine. very very odd.
I have since tried updating the kernel to ninpho 2.1.3 from the 2.0.5 that comes with lite'ning 6.1, but that made no difference.
Someone suggested i try a wifi fix app from the market so i downloaded "FXR wifi fix and rescue" and ran that. It ran ok, wiped all my wifi settings and i restarted, but it has not solved the problem at all.
i find it very very odd since if it was a problem with the kernel OR the rom then everyone would surely have exactly the same problem. I know some people report wifi issues but most dont seem to.
anyone have any other ideas?

The odd thing is that it worked before the update. That means that it will most likely be software related.
You could try flashing something totally different like MIUI or CM. They provide kernels too, so this might resolve it, if your kernel and rom don't "like each other". This usually shouldn't happen, but updates breaking wifi shouldn't too. So it might be worth a try.

if i went to something completely different i assume i would have to factory reset the phone to wipe it first? (or factory reset it AFTER installing the new rom?)
was trying to avoid wiping it as i dont want to spend endless hours setting up everything again. i have backed it up with the free titanium but id still like to not have to find out whether the restore actually puts everything back properly
its very odd as its not completely broken, sometimes it does actually work, and it always connects to the router itself without any problem.

Probably wrong modem for you, flash another one. You can find modems in the developement section.

ok thanks I will have a look at that. It is currently on XXKH3 which is what came with lite'ning 6.1. i am confused though, all SGS2 hardware is identical so if this modem in 6.1 is causing this issue, wouldnt it affect every sgs2 that uses that modem?
I found the "shipped modem collection" post in the original development thread so have asked in there which modem i should try.
ok apparently i should try XXKI3. for o2 UK provider.
although i have now read that wifi is not managed by modem but by kernel only. if this is true then modem will not help me

Well, if the wifi is not managed by the modem, try what I proposed you earlier. The simplest would be to flash CM. Make a backup of your current rom, then do a full wipe and install CM.
As for your data:
1. Titanium backup restores your apps with their data (if you wish). That means that, for example, your games will keep their saves, other apps their settings and so on.
2. Assuming that you have a google-account, you don't have to worry about your contacts, calender,... Just sync it before you flash.
3. The backup you make in CWM will backup everything in case CM doesn't work for you.
In case it does work and you'll want to keep it, the other two other parts of your backup will minimize the remaining work. Note that you shouldn't restore "standard"-apps like the media-player or the SMS-app if titanium backup tells you that the app is not currently installed on your fresh CM. This means that CM uses it's own media player or SMS app. It could lead into problems to mix TouchWiz apps with CM.
A side-note:
Don't use the "stable" version. It had more bugs than expected and they made it a RC again. However, it is still in the stable folder. Get the latest nightly.

yep i think it is kernel. just noticed that 1.4 had cf-root, 6.1 had ninph 2.0.5 and i then tried ninph 2.1.3 and both ninph's have had the issue. i just tried speedmod k2-13 as i already had that downloaded and so far the wifi has been ok so hopefully thats it fixed. i guess it was something to do with ninph (i am thinking that because i have it set to sleep the wifi when the screen is off that somehow ninph is not handling this properly).
possibly one good thing to come of it all, ive updated the modem to KI3 which is supposedly the best one for o2 UK so i may even save more battery and speedmod is meant to be really good for battery too. I still have lite'ning on it at the moment.
i might have a look at CM anyway but i do kinda like lite'ning (although i havent actually used anything else since the phone came with it!)
also need to look at wakelocks to see if i can save some more, although not sure how i go about 'fixing' them at the moment

The choice between CM, MIUI and the stock mods is the choice between three different UI's.
I've had all three of them for some time. As you got CWM, you can just create a backup and do a sightseeing tour through the world of custom roms. Believe me, it's absolutely worth it. To get an idea of the main differences, I've written a short overview for you:
Stock mods use Samsung's TouchWiz. The default user interface that you get when buying a Samsung Android phone. So it mostly looks and "feels" the same and you can't do much about it.
CyanogenMod gives you the pure Android user interface. It's the closest to the Nexus phones by google, but gives you some extras. It is much more customizable than stock roms. It's sleek and fast.
MIUI is a whole different story. They're "Redefining Android". I think calling MIUI an "Android custom rom" is an understatement. It's an entire OS. The result of putting the best from iOS and Android into one powerful OS. It adds tons of useful(!) features. If you've ever used Windows Phone 7 or an iPhone, you know what a big step forwards Android is when it comes to features. Switching from Android to MIUI is just like that. There is just so much more. It is BY FAR the most customizable Android you can get.
Wow. If I look at how long the texts are, I see that I'm pretty biased. :O
Well maybe because I've switched so often between them. The stock roms had no chance, because after I used one of the others I found out that TouchWiz doesn't cut it anymore. I hate how "iPhone-ish" MIUI is, but if I flash CyanogenMod I just miss so much. Giving you a list of what MIUI adds would be another long post of this length.

cool thanks will have a look at MIUI at some point.
spoke too soon earlier, the wifi is maybe slightly better on this speedmod kernel BUT when i wake the phone from sleep, it takes about 30 seconds before i can connect to the net with anything. the phone connects to the wifi straight away, but i have no connectivity for a good 30 seconds and then it starts working. (its not the router, i am getting a connection and an IP pretty much as soon as i wake the phone). also the 30 seconds or so only STARTS once i try to connect to something. if i wake the phone and do something that does not want net access for a few mins and THEN try to get on the net via wifi (which shows as connected the entire time) then again i have to wait about 30 seconds from when it first tries to connect before it will start working.

ok slightly confused again.
I have lite'ning 6.1, speedmod k2-13 kernel and XXKI3 modem. I am trying to get cwm installed so i can make a full backup image of the entire phone while i try to sort out the wifi issues. i downloaded rom manager from market, and selected the firstion option in the app 'flash clockworkmod recovery'. it brings up a menu saying 'confirm phone model' with AT&T galaxy S2, a coulpe of i9000s and a plain "Samsung Galaxy S2" which is the one i selected. it downloads something and says successfully downloaded clockwork mod recovery.
i then choose reboot into recovery. when rebooting it attemps to install something but then says "failed to verify whole-file signature" and aborts. so im just stuck with the standard recovery instead.
so now im confused, have i missed something?

Ehhhhm, you don't need to do it.
Have a look at the features of the speed-mod-kernel:
Current features:
Root and CWM:
- Automatically installs root (su)
- CWM 4.0.1.5 recovery
It already installs it right away.
Just in case you messed something up. You should flash the kernel again.
Besides that you don't need the RomManager at all. Just shut your phone down and boot into the recovery with the key-combo. Create and restore backups from there.

[Q] U8800-official 2.3.5-rooted-random reboots

Updated to official 2.3.5 rooted, added back the pink screen, not done much else except installed a few apps.
Getting random reboots while phone is sleeping. Never happens while actively using phone. My phone will be on my desk and next thing I know it restarts.
Anybody else have this problem or found a solution?
I need to find out if it is the rom or something else causing the problem so I can start to troubleshoot it.

Turn OFF wifi when you're not using the phone. problem solved

If not work try this :
Goto CPU menu -> smartass v2 and make low and high cpu speed settings to 1 ghz.
This will also increase Battery life and must fix random rebooting.
Other way is clear caches and install rom again.

Loureiro:
I'll try turning off the wifi. It sounds like a highly likely solution since: 1) I've only seen my phone at home 2) I always turn wifi on at home.
Is there a specific reason why wifi is causing reboots? Maybe something I can find a fix for?
technogod:
Don't have custom kernal installed, so I can't alter the CPU parameters. Wanted to make sure the phone was stable at stock before changing the kernal.
Speaking of which, what's the most stable kernal for overclocking the 2.3 stock rom?
I'll try clearing the caches as well.
Thanks.

The wifi bug is known fault with the .35 kernel found in the official upgrade. hopefully it will be fixed next week fingers and toes crossed. I am not sure if any of the kernel dev's have found a fix yet.

Without cpu parameters, only way i am found that : clear three caches with clockwork and reinstall your rom. It's working on stock roms or custom roms. I think, this is not rom problem. There is different something. Cache clearing solves problem. Resetting problem started on my phone when i start to try other roms.
I am using miui 2.2.3 now and i will setup 2.2.10 version today. While using stock rom, i have some resetting problem. But now, my phone working without self-reset.
