[Q] Wi-fi doesn't work what to do?

I tried to use different ROMs and Radios and no one can help me. When I turn on wi-fi it shows me "Error" all the time. What can I do to fix it? Some sayd me to open my phone, find wi-fi module and check a cable, but I don't have any chance to do it. What can you advise me? Thank

I had the same problem with HoneySense RC1, but I reflashed the ROM then UNITY V4 w/o booting between and has been working good...that's what I did with Honeysense but without knowing what ROM you're using it's hard to say what the problem is!!!!

I have Shokouhi Saga G2 ROM. But I installed a lot of different ROMs and no one helped me. Maybe today or tommorow I will install UNITY v4 and then write there what will happen. thank
installed UNITY v4 and nothing changed. Maybe i've done something wrong? Can You say me, how i should use this? I loaded ROM manager, booted into Recovery and flashed UNITY. What else? Thank

You will need to do a fresh install of a ROM but this has worked for me in the past also... Just flash the .zip like a ROM, then flash your ROM and then UNITY4 (only if you're using a Sense ROM)!!! Try that on for size, if that doesn't work you need someone more talented than I am!!!

Done all this what you said me and nothing changed I turned on a wi-fi and it started and tried to find network, but after 5 seconds it shows me "can not start a scan for a network"
Maybe when I dropped my phone on the ground and that damaged a wi-fi module...

Wi-Fi and GPS Keep Engaging

I've searched the forum and can't see a solution to this problem.
My wi-fi keeps turning on even though I have switched it off and even if I put the phone in airplane mode, it switches back in.
Also, the GPS constantly tries to engage. The warning pops up which says, "By selecting "Standalone GPS Services", you are enabling access to all location information..." and it has 'disagree' and 'agree' at the end. If I click 'disagree' it goes away then reappears a short time later. If I click 'agree', the GPS goes on.
I have run an virus check which was negative.
I have ICS build 4.1.B.0.587 and it has recently been rooted.
I tried locking wi-fi with some software, but that didn't work.
Any ideas anybody?

if your phone is non-modded (custom kernel, rom etc.) re-install the firmware you're currently using by re-flashing it via flash tool 6 or higher..
if it is modded (root, rom, kernel etc.) re-flash the kernel or change it/re-flash the rom or change it

Thanks MrModMan, I did as you recommended. My phone was rooted, so I downgraded the kernel again (using the LT18i downgrade as I was told that this would be OK on my LT15i by another member), re-rooted using the DooMLorD tool, then flashed the kernel again (using the LT15i ftf for .587 build).
The problem still exists.
I suspected that it may relate to an app which uses GPS/Wi-fi connectivity, maybe Google Maps. I backed up Google maps, then uninstalled using Titanium Backup, but the problem's still there.

Here's an update. I reinstalled the latest version of ICS and have not rooted my phone, The phone is not now reconnecting to wi-fi and the GPS nag screen has stopped appearing, so evidently there is something wrong with the rooting procedure that I used for the .587 build of ICS. I can say that I did follow the procedure outlined on this forum to the letter. Maybe somebody with more technical know-how can determine what the problem is.

wifi do not turn on

Strange things happen to my i9195... suddenly out of the blue,wifi won't turn on neither from quick settings panel nor the settings itself...
Everything else works as it should(data,bluetooth,airplane,gps,sound etc) but the wifi setting tries to turn on but immediately turns of. anyone had this problem?
and more important... a solution??????????

thanks guys for your replies...
i was on stock rooted xxuamf4, i flashed both xxuamh3 and xxuamg8 (these two i had already downloaded) but problem remained. just to eliminate software issue , as a last resort i flashed CM 10.1.3 and magically my device was fully functional again( by the way ..:good: to CM...).
So WTF? i 'll try later to flash a stock non rooted fw and see what will happen...
p.s : anyone know how to change baseband? in my sgs3 mini i used to flash different modem for that. what works for this device?
p.s 2 : thanks again for your time guys!:good:

flashing back stock firmware , problem reappeared! it seems something has to do with knox , because every time i try to open wifi a toasted notification appears "prevention information... the device as detected...bla...bla...bla"
the thing is that if i root my phone and completely delete knox,knox agent,store and container agent, the notification stops but the wifi setting still cannot be enable.
any ideas????

Back to report that re-rooting with arco's method but with rootkit v2 (that includes kernel) seems to solve the issue! the steps i follow was :
1) gain root
2) install cwm recovery
3) with es explorer delete knox store,knox agent, container agent (both apk and odex files)
4) reboot to cwm recovery
5) clear cache and davlik cache
6) reboot and RESURRECTION!!!:good:

i think it's a kernel related issue. But first in order to eliminated hardware problem possibility, try to flash a cm rom. If your wifi and bluetooth works then you can be sure it's not a hardware failure. in my case flashing a different kernel solved the issue.
p.s : if you find a way to change baseband version ,please share the way!!!

Baseband : Nd1
When i want to connectt to wifi i enter password.. As soon as i hit the connectt button wifi signal will desappear... I updated the frameware but no sucsess...
How to solve?
Is it hardware issue?

Same problem for me (1st post): new i9195 with latest XXUCNK1, never flashed before,
install twrp and make a backup, install CM-12.1 and CM-13 without any issue,
After restore to KK using my twrp backup I can't turn on wifi,
solution was to flash Modem_I9195XXUCNK1.tar from modem thread.
I notice that twrp doesn't restore previous modem I update to XXUCOL1

[Q] Xperia arc s wifi problem CM11

I have Arc S and CM11 on it. I don't have latest update since on latest messaging app is buggy. When i connect to open network everything works fine, but if i try to connect to protected network, it doesn't connect properly. I did not reflash CM11 to check if it fixes problem, nor factory reset. My friend told me it is wifi modules problem but i can't find any for this phone/ROM. Any help appreciated!
EDIT: I will reflash only if i need to (if it solved problem to anyone), cause i have many apps, accounts, etc...

I've installed DarkAnzul kernel 3.4 with custom ROM AORP 4.4.2 RC1.2 .
Everything is fine, except for wifi. I can't switch in ON.
I read in some thread that maybe installing wifi modules from DarkAnzu would arrange it. But just flashed it and it's not working either.
Any help would be appreciated.
Thanks.
Alex.

If you get the problem connecting with protected network since the day you flashed your rom, reason may come from your rom or kernel. Try to reflash another kernel, if it does not help then you should try another rom. In case your wifi problem has just happened recently, factory reset or reflash, it's up to you.
Hope it help, you can wait for other suggestions!

Until now, CM11 is not really stable enough yet, however, our developers still keep working hard to make it better, just waiting.

Older versions were much more stable than last few. I (almost) thought they would soon release it finally, until now...

It worked!

I've just flashed the boot.img inside the .zip . Rebooted.
Wifi is working perfect!
AORP rom is the best 4.4.2 rom I've tried on my Arc S. It's fast, stable and now everything works.
Thanks motlanvamaimai for the help.

[Q] Installing rom(slimkat) from Stock 4.4.2

Hello. I've been flashing/installing customs roms all day..
I can't seem to solve my problem. Wi-fi wont connect in any of 4.4.x custom roms(slimkat,paranoid..etc)
however it works fine on 4.2.2, 4.4.2 stock and LRS rom
full packaged rom seems to be only solution for me.
heres what i did
My device came with 4.4.2.
I downgraded to 4.2.2
rooted
used loki/twrp package to install twrp 2.6.3.2
wiped data/cache/dalvik
installed custom rom
boots device fine but wifi wont connect(i do see list of wifi network)
tried following
higher version of twrp(s)
tried 4.2.2/4.4.2 flashable bootstacks
tried different type of roms from infected website
tried flashing custom roms after flashing 4.2.2 + 4.4.2 flashable stock roms
none seems to be working.
=( are there any other steps i need to do?
perhaps missing correct kernels?
thanks in advance.

What model gpad do you have? It looks like a v500. Sometimes a factory reset after ROM install helps. Does android settings show the WiFi MAC address?
If it does the kernel at least detects the WiFi hardware on a basic level.
I do know that slimkat after installing seems to require a reboot for things to settle. However as i recall that was for some of the sensors not wifi. Did you reboot after install?
Also did you set the WiFi region in the advanced part of the WiFi settings?

v500
did reset/reboot still doesnt work.
mac address/region information(changed to us/can/europe for test) is there.
i did notice that there is no bluetooth address however i did install many other custom rom.
this isn't the only rom with the problem.

no i tried to fix but no go.
wifi problem remains.

I am using a newer version of recovery than you are. I will have to look around and see what I did differently if I get a chance...
