Wifi unable to start unable to stop tether not working

I searched all over the internet and was unable to find an answer or solution.
I Installed RegawMOD's latest rom.
Wifi was working just fine, The last time i remember that it was working was before used the toolbox and before installing 2 or 3 games. I think that something messed with my wifi driver because when i try to turn it on it says "unable to start wifi", then when i try to turn on airplane mode it says "unable to turn off wifi" When i try to run the Wireless Tether it says that the tethering started with errors that i should check the log. The log says the following from the bottom going up:
Tethering now running DONE
Enabling access control DONE
Enabling IP Forwarding DONE
Enabling NAT rules DONE
Activating wifi Interface FAILED
Configuring WIfi Interface FAILED
loading wlan.ko module FAILED
Does anybody have any useful information that may pertain to my situation?
Everything else is working perfectly. this is the only thing that has ceased to work.

This belongs in Q&A, not Dev.

Thread moved to Q&A.

This is a kernal issue go with darchDroid 2.7, it will fix that problem

did you flash a different kernel? What version of tether?
if you really feel it's the driver, pull the wlan.ko from the original zip and push it into place to overwrite.

I just encountered the same problem as the OP on my HTC Hero CDMA. I rooted my phone with RegawMOD3.0 yesterday and within a few hours my Wifi stopped working. I'm getting "unable to start wifi" and "unable to stop wifi" in airplane mode. The only other thing I did was get the Adblocker app, which i thought may have cause an issue so I did a factory reset on my phone and still no dice. From what I've read it's either the kernel or wifi driver and I'm unsure what one to try and fix first. Any help would be greatly appreciated, thanks in advance.

Well, whatever the issue was it was solved when I put cynogen 7.2 Nightly in. My Wifi is working perfectly now.

Yeah. I'm impressed they're still making nightlies for this phone.

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?

[Q] Wifi no longer working after setting up VPN

I'm on CM dal .32 test build 3.1
Today I tried setting up a VPN but failed. The screen became frozen and I decided to reboot my Nook Color. However, after rebooting my wifi is no longer working. It says "connecting" but then "disconnected" Scan option didn't show any network.
Anyone can help me?

CM7.0.3 with Nook Color no longer works
Hi,
I've run into the same issue with my nook color. I'm not sure if this is an issue with the kernel or the physical device. I know that this is not a router issue since I'm able to connect other machines to my router. Also, I no longer see any other hotspots with the Nook.
I tried some suggestions that I've found on other websites, which include
Shutdown Tablet and start again
Re-install Google Apps
Use Fix Permissions in Rom Manager
None of these work. Any suggestions or is this a known bug?

Same here, I was using nightly 115 with Dalingrin's 6/18 OC kernel when the problem started. I've since rebooted multiple times, fixed permission both from CWM and in Rom Manager, flashed nightly 117 without flashing OC kernel, and still haven't solved the problem.
Wifi just stays "Connecting" and then changed to "Disconnected" briefly and go back to "Connecting" again.

Just reflash your ROM or the latest ROM and DON'T mess with any OC kernels.
Does it work? If so, try the OC kernel again. If it fails, let Dal know in his OC kernel thread, and just re-flash your ROM again to return to the stock kernel. Wipe cache/dalvik as necessary, but don't wipe data and you're not going to lose anything.
One suggestion I have is if you're using AES on your router, try changing from WPA2 to WPA or changing WPA AES (or AES+TKIP) to just WPA TKIP and see if that fixes the problem.
There's a long standing issue with some routers regarding AES in Android, and apparently some laptops also had this issue on older kernels.

Flashing to the latest rom without messing with the kernel was the first thing I tried (other than turning wifi on and off multiple times). It didn't work.
What eventually worked was when I wiped data and factory reset it. Some how that fixed the wifi.
The strange thing is I had just recently factory re-setted coming from an old (pre 2.6.32) nightly a couple of days ago, and had not gotten around to installing much, and I did not restore from backup. i.e. the only thing installed when the wifi problem suddenly appeared were the google apps, Aldiko, QuickPic, Rom Manager, MoboPlayer, and a few ADW themes. None of which sound like they should do anything that messes up the wifi.
I doubt it has anything to do with the router, because I tried connecting it to my router (tkip), hotspot from my android phone (unlocked) and hotspot from my iphone (unlocked). My phone just did not see any network around at all, not even the 5-6 different network from other people in the building.
As mentioned, I have factory wiped my NC and all is fine again now, so I'm not too concerned right now, just curious what could have caused the problem.

[Q] wifi problem with Resurrection Remix®v5.0.8

I would say that Resurrection Remix® 4.4.2 KitKat v5.0.8 is one of the best ROM made for our i9305, it is My favorite actually. But there is only one problem that bothers me alot, and that's the WiFi that is connected but no internet access. I always have to reboot my mobile wifi device just to reconnect again and it never happens in the other ROM that I've use, only with this one. I have also seen this problem being ask in the thread but no answer was given. I would like to ask if it is a bug or somewhat, because it is not only me who is having this problem. I would be delighted if some would help me with this.
And also I have actually followed all the instruction in how to install the ROM. I am also using latest cwm recovery.

wifi isnt working
same problem here ;(

Solved
I was facing the same problem.
Actually, this problem is related to DNS settings so, I changed network settings and set the DNS manually.
Go To settings -> wifi -> (long press) your wifi SSID -> modify network -> (check) show advanced options and now set the DNS1 and DNS2 fields according to the wifi network you are using.
One temporary solution is: connect to your wifi network and use Psiphon (tunneling app).

I too had this problem... While entering password for Wi-Fi.... Just set the IP to Static and enter the respective details like IP,DNS1 and DNS2 and Gateway... You are good to go..

[PROBLEM] Kernel Panic and Wifi greyed

A friend of mine asked me to repair his brother's phone that recently showed a "Kernel Panic" error message on 4.1.2 stock rom (followed by reboot). I read on the internet that it could be caused by a hardware failure but someone "fixed" the problem installing an AOSP rom (I know, it doesn't make much sense but it seems to be working for now). I installed cm11 by janice and AOSP Rc3 by J-Team (I can't provide you the links but they should be both in the Developement section for this phone). They both worked smoothly and kernel panic has not showed up (for now) but then, when I got everything working, I noticed I couldn't use the wifi function because the on-off switch is greyed out and unable to work. In the Wifi tab I got this constant message (Searching for Wifi network - translation may be inaccurate). Is there anything I can do to fix this problem via software?

Wifi and Kernel panic
Same problem here.Kernel panic message dont apear evry time.But i have another problem when i tried to swich on wifi it reboot my phone(Galaxy S Advance recently flashed to 4.1.2 stock whit odin).
Did you manage to do something?Btw my bluetooth is working, some peoples encoutered problems whit BT too.
