Wifi on Cyanogen issues

I just finally got sick of waiting for an official Froyo(Bell isn't about to give me an upgrade anyhow.) So I went to a froyo rom that was based on one of the stock roms. But I figured since I'm rooted anyhow why not play around, and grabbed cyanogen 6.1 and installed it. Then I end up with the issue of its not connecting to my wifi, I have no issues on the stock 2.2 roms. One thing I have noticed is the cyanogen shows the network as wep, but it's actually wpa encrypted. I flashed into it from the stock without clearing it first and it worked until I shut off and came back to it. Any ideas on what might be the issue. I'm fairly new but I did look and couldn't find anything to fix this.

I assume you flashed 6.1 stable version? I have no issue whatsoever on my device (and I also used official froyo previously). Did you wipe all before flashing 6.1?

He said he "flashed without cleaning"...so I presume no wipe. This could be the problem, a wipe is strongly adviced if going to CM from a non CM ROM. Also check the number of WiFi channels set by default in advanced settings of wifi. It is set for 11 and if the router is set to 13 or 14 it could not work

I had the same problem when i was installing CM6.1. (with wipe)
The phone could just se a wep version of my network and not the wpa that i have. But after i turned on and off the wifi a couple of times i suddenly saw the wpa version of my network and after i connected to that the problem was solved. I also did click "forget network" on the wep version.
Hope this will help you

Trying this now but no go. Sometimes will flash it as wpa and then jump back to wep. This is after a full wipe. What I was trying to say was once I flashed in without wiping and it worked for a bit but jumped right back to not working, after the phone going to sleep.

Bump.
Any insight into this issue? Still only reading my network as wep.

Try installing "WiFi Advanced Configration Editor" from the market. You should be able to change to WPA manually with it.

Did you try to reset your wifi router?sometimes the issues came up from wifi router, not the phone itself.
Mine is fine. I share my broadband wifi to my phone using connectify.
The only problem remains is wifi disconnect frequently, but I heard that it's due to a new kernel which I use (.32 kernel)
hope it helps

Ya reset the router a few times, and it still came up like that. I did install the wifi advance config software mentioned it seemed to fix it. I didn't actually set anything up on it and it seems to have fixed it. Thanks.

CM 6.1 messed up my wifi. Wiped everything, but it suddenly doesn't find my networks.
Wiped again and restored nandroid backup of working rom but STILL the same issue now!! Can I flash the wifi drivers again somehow?

Wifi stuck at "obtaining IP address" - Stock LPY

I am on rooted stock LPY. I noticed that whenever I try to connect to wifi it says connecting then stuck at obtaining ip address and then disconnected. I have tried more than one router and I am getting the same results. I have googled this and one solution is to have a static ip address. The problem is that this setting is no longer available in ICS. Any idea how to fix this without wiping (I am too afraid to wipe given all the fuss about it).

Did you flash the LPY Rom with or without full wipe? That might be the cause.
You can flash a new modem and see if it's fixed. I can't think of anything else...

Experiment with frequency band under advanced wifi settings.

When i was on ICS i had the same issue.
This is what made it work for me:
- remove network from device, disable wifi and turn off device
- turn off internet modem(if you have any) and router, wait at least 2 min.
- turn on modem and router
- turn on device, enable wifi and connect to network
Hope it works out for you

Tried that and still it is not working. I guess I will pass on wifi for now.You said you have been on ICS, so how did you managed to revert back and what rom are using now. Thanks for the tip

With wifi disabled, if you have root, go to /data/misc/dhcp/ and delete all 3 files there.
I had problems on LPY where wifi would connect but ip address wouldn't get assigned.
Deleting the 3 files in /data/misc/dhcp/ fixed it for me. No probs since

Re-flash with wifi off, make the sincronization with google on 3g and then turn on wi-fi connection

I gathered all my courage and flashed a pre rooted GBrom via pc Odin, no wipes, no cleaning, no nothing . once back on GB i only performed one hard reset and felt confident enough to flash CWM back on it. I would give you the link, but am on my phone right now and can't find it, but the rom is in Bodivas thread around here.
It worked out well for me, but as you probably know...no garantuees.
Btw, sorry to see your wifi still not working

Hmm. Those 3/4 files should get recreated if DHCP is working properly on your phone.
Perhaps you phone is missing stuff in /system/etc/dhcpcd/?
Another thing just popped into my mind - did you restore your Wifi Access point details via Titanium Backup? I think that may have been an issue for me too on LPY... don't restore is best.
Or just downgrade to GB, full wipe and flash LPF

Do you have soundhound or dolphin browser hd installed?
Sent from my GT-N7000 using xda premium

I'm on LPY too. When I'm at office I have no issues with wifi connection but when I'm back home I start to have issues. It shows connected and I get no error or disconnected messages what so ever. But device looses wifi connection short time after connected. I check wifi connection on laptop and there is no problem but on my Note even though it shows connected I have no connection. Turning wifi off/on fixes it sometimes but most if the time it doesn't.

Just flashed / rooted ZSLPF ICS following Dr. Ketan's guide and now I have wifi again . Having read so many posts about this, it would appear that the wifi issue has something to do with the CF-Root kerenal. Thanks buddy

Go to Settings >> Wireless and Networks >> Turn on WiFi

Assign your IP address and leave other credentials as they are. Save settings and you are done.

Wifi issues on CM9/CM10

Hi,
first of all I want to thank all of you pushing the SGS to the newest level of smartphone software.
Here is the problem:
I installed CM9 exactly as it was discribed in the tutorials. Everything is working fine, except the wifi module.
When the device is in the airplane mode and wlan is activated, there is no problem, but when I turn off the airplane mode and turn it on again after a short time, I get a reboot or the wlan settings screen freezes at "WLAN is activating", when I want to turn on WIFI again.
I tried all available kernels (devil, semaphore,...), tried TeamNyx RC5, tried CM10 and nothing improved this situation!
Flashing the JVU(or another stock Gingerbread) via Odin, I can use the WLAN correctly.
Thanks for your efforts!
EDIT:
I get the same problem on CM10
Using CM7 everything works perfect!
Please: If you got the same problem, answer to this thread!

Same here on Vibrant. CM9 and 10 only.

The 3G works fine on pac?
However, you can try to flash the boot.img in fastboot and see.
And, what's your problem with the recovery?

I am having the same problem too. Was previously on trickdroid. Flashed Revolt ROM and my wifi wasnt connecting to my home network. It could detect, prompted for the network password but after that it just wouldnt connect. So i looked deeper in the phone's information and discovered that my phone's IP address was in a different IP address range. It was 10.x.x.x and my home router was 192.x.x.x. My sister's S4 had no wifi problems (unrooted) and hers was 192.x.x.x. So now I'm trying to set my HTC One's IP address to 192.x.x.x. Still trying to figure a way out though. Hopefully it will work. Give it a try!

Flashed pre-rooted ROM, wifi no longer working (authentication error)

I installed lyriquidperfection's stock pre-rooted ROM (here: http://forum.xda-developers.com/showthread.php?t=1942150), everything seems to work ok so far except for Wi-Fi.
The phone will not connect to my home network, telling me the password is incorrect and displaying 'authentication error'. WPA2 password is definitely correct.
Can anyone suggest what might be the problem?

I'm also getting a new symbol in the right hand side of the notification bar, it is a big N with what looks like a wifi signal next to it.. what does that mean?

I hope you didn't do this... you flashed a I9305 firmware on a I9300 device? Or you just asked on the wrong Q&A section? There's a separate Q&A section for the I9305 device so...

Oh right, it appears I've posted in the wrong section. I definitely have an i9305.
Like I said almost everything seems to be working fine (in fact other than the boot screen I noticed almost no difference after flashing) except for Wi-Fi.
But I have also noticed one more issue, the phone will not connect to my PC in "Media Player" mode. It connects fine in "camera" mode. My old phone (galaxy W) used to connect fine in all modes and I have transferred files to this phone in Media Player mode before flashing this ROM...
Anyways most important issue is getting Wi-Fi to work.. any ideas?

I have no idea since I don't own a I9305 device. I'll just report this post to be moved to the I9305 Q&A section and from there maybe you'll get a solution to your problem.

Clear any caches ie Dalvik, system and user.
Then shut down and pull the battery for a min of 20 seconds.
Reset your modem / router if this fails to work try and connect without any security to see if this is an issue.
If all ok reactivate your security and try again.
As for your usb go to settings / advanced settings and make sure usb debugging is enabled.
Reinstall your Samsung drivers on your PC and remove Kies if you have it installed, reboot PC then all should be well. :good:
Final sanction if all else fails reinstall the rom but clear all your data first.

wifi is controlled by the baseband

Simply Wrong please read the faqs and guides .
Wifi is not baseband .

another simple suggestion for you, why not try to set the network into connect without password,you can find out if the phone is ok in connecting with router.

you are right,baseband controls the signal only，wifi is by the rom～

Which is what I suggested in my previous post, please read before giving an answer.

I´ve had the same Problem with my S3 LTE and the Speedport router in germany.
There is a setting in the Wlan Menu ( Save energy on Wifi ) you have to disable it. You can also Update your Router to the newest Firmware.
After that it had worked for me
