Hi
I have a defy that has been happily running cm7.1 for a month or two. I am on holiday and have been using the defy to connect to wifi hotspots every 3-4 days, so have not updated anything or tinkered with settings etc.
The defy has just stopped scanning for networks, or finding wifi networks it has already used.
Turn on wifi and the defy does 'connecting' and then 'disconnected' every wifi network it has settings for is 'not in range' click on scan and it does nothing.
This is really frustrating as instead of spending 10mins in a wifi hotspot downloading stuff to read latter, I now have to search for internet cafes and spend an hour or two to keep on top of work.
Help would be appreciated, although I wont have any way of connecting the defy to a computer until i get home in a weeks time.
You could try forgetting every network and then press menu>scan
thanks, i have not deleted/forgotten all the networks, just the local ones. Sadly this has had no effect.
hey
Yup. ... even I had this problem once.
Solution - do a fresh flashing from the sbf and then the rom ... no nandroid restore .
Worked for me ( though I had to do the process twice )
Temme how it goes
I have a similar problem on GGL ROM (Defy Green Lens [Android 2.3.6]), which is a slightly modded version of the stock Defy+ ROM from Tmobile DE. Wifi worked flawlessly on all earlier ROMs (eclair, froyo, miui, cm7 and cm9). Toggling the battery settings to performance mode seems to delay the problem, but at some point the device loses the connection and scans for networks that other devices have managed to hold a stable connection to.

It happened me twice (with cm7). The only solution that worked for me was to delete (or rename) /data/misc/wifi/wpa_supplicant.conf and reboot. To do this, you need to have root permission and use root explorer/adb/shell emulator or even sshd
Keep in mind that you will have to put again all the passwords, so if you copy somewhere the wpa_supplicant.conf is better.
I read somewhere that performing a backup with titanium backup just regarding the wi-fi AP list (and restoring it) worked, but I never tried.
If that worked you could try to rename wpa_supplicant.conf to wpa_supplicant.conf.bak. Reboot. Delete newly created (by the system) wpa_supplicant.conf and rename wpa_supplicant.conf.bak to wpa_supplicant.conf and reboot. It should work.
Bye,
Peppe
PS: @yamandude it is clear that flashing an sbf will work, but that's like killing a mosquito with an atomic bomb
I had this problem too when I was on a holiday in a hotel that all my friends were happily surfing the internet with the hotel Wifi while I'm the only one struggling trying to connect. The Defy sees the Wifi/routers but wouldn't connect it no matter how I set or tweak the settings.. I end up restoring my backup via CWM when I got back home and solved it. The above work around would surely save a treat considering I wouldn't need to restore my entire backup.

Bought my Galaxy yesterday and it works fine but on one point. Yesterday I was able to find the home network of my friend in his house. I could connect to the internet with that as well as through 3g. But later at my place it does not work with any home network. When I try Settings, Wireless and network, Wi-Fi settings and Wi-Fi, the phone turns on Wi-Fi and scans for some seconds and the leaves a message that says "Unable to scan networks".
Maybe I have switched on or off something accidentally as I am a new user on this phone? Anyone for help?
turn off the phone
then turn it back on
in another words, reboot your phone, seems like it got stuck in some WiFi bug
It does not seem to help. I even took out the battery. Still unable to to scan
you can try this
*2767*3855# WARNING! FACTORY DATA WIPE AND RESET as soon as you enter the last # use it only if you want to clean wipe your phone

I really don't want that as long as I also cannot backup the video in it. Have not got the Kies program to recognize the phone yet.
Maybe there is another way to set the scan possibility?

you don't need kies
see the last secret code?
It defaults to User space. I do not yet have any extra Micro SD card. Is it that what means with User space?
Tried that last command and do have at least one file of each in the folders, but the phone answers for each of them that the files are not ready? What else is there to be done?
Had same problem, tried factory reset... didn't solve it. any ideas? it can't get an ip address and it used to work
probably the next best thing is to use Odin to reflash the modem file to the phone
or a full flash to the latest firmware
Same problem appeared on my SGS. Boy this sucks. The wifi became "hard" to connect sometimes. Or I could connect but had no internet access. Then I disconnect and connect several times to have net access.
One hour ago the wifi died. I turn it on it says "Unable to search for networks" and shuts itself off.
WTF. I have to reflash!!!! Not good. Also I don't know what caused this. I'm on JM2 with One Click Lag fix 2.1
one thing is for sure, the STOCK rom has no problem with that
so it is either a Router thing, or a firmware specific problem

JM2 isn't a final release firmware. Realistically, if you want everything (well, other than GPS) to "just work", stick to official firmware.
Well, I for one, have only the the official firmware and it is the latest one what I have learned. Still the phone behaves as in my original post after just a couple of hours. Is this and other peoples beautiful Samsung Galaxy model not tested enough by Samsung? Has anyone more information than we have?

I agree thats Help me. or you can try upload update.zip (file to make root) on your device and flash that can help too.
Hi all! Thank you for your inputs to my problem. I have now got it working. For those who are interested how, I can tell you that I only did a simple Factory Reset command.
problem solved!
I had the same problem.
I was trying to configure a invisible ssid and by distraction I created a normal WPA 2 network, ending up with two networks with the same ssid (when I was turning off the wifi, it wouldn't go off at the first try, weird, )
Solution:
Edit the "/data/wifi/bcm_supp.conf" (with root permission) and eliminate the duplicated network, problem solved! At least in my case (no need for factory reset )

Today I went to my university after a long time and tried to get access to the university network (eduroam) with an app called Wifi Helper (you have probably already heard about it). After a few tries my wifi suddenly stopped working and now goes off everytime I try to search for networks. Even now at home when I try to connect to my home network it doesn't work and my phone doesnt find neither my network or the networks from the neighbors. Also all the networks saved in my phone disappeared and I can't add any new network configuration.
To summarize:
-if I turn the wifi on the phone makes a scan for wifi-networks but doesn't find any
-the wifi goes off after 15-20 seconds
-I can't add new networks
I made a search in the forum but didn't find anything similar. I'm not 100% sure wifi helper caused this but I would say I'm 99,99% sure.
Until now I've tried uninstalling wifi helper, rebooting the phone, taking out the battery but nothing seems to help....so I would recommend not to use this app (if it's allowed to make such a recommendation).
I wish this has a solution and the wireless can work again. Hopefully someone can help me here or give me a couple of ideas (since this doesn't seem to be a common issue)
Edit: can someone tell me what files you have in /data/misc/wifi ? I checked in my phone with root explorer and I only found reg_code and wpa_supplicant.conf ...maybe wifi helper deleted something there.
Try a factory restet, its a bit of a pain but it should fix it
You mean to flash to the original firmware? X_X
I hope that's not the only way...
Maybe there's something missing in my wifi folder that I could compare with other phones.
I think wifi helper deleted almost everything in my wpa_supplicant.conf
This is all I got in there:
ctrl_interface=tiwlan0
update_config=1
can someone check if thats ok?
ctrl_interface=DIR=/data/system/wpa_supplicant GROUP=system
update_config=1
network={
Network info goes here
}

wifi helper screw-up your wpa_supplicant.conf, it happened to me 2.
Update the "ctrl_interface=DIR=/data/system/wpa_supplicant GROUP=system" like Bourbon Brain mentioned and your wifi will work normal again (hope you know how to do that).
Thanks for your help
I had to backup all my data to do the factory reset (I had totally forgotten about it ) and it took me quite a lot of time to set everything back to normal but it worked. After that the only difference I could find was in wpa_supplicant.conf so I guess if I had changed it to what Bourbon Brain and gpmg762 said it would have worked too (even much easier). Unfortunately I didn't wait till today
Glad to help regardless

hello all,
The last week I was using my wifi without problems in any wifi, I left the wifi on and after a while my phone shutdowned (lost charge). After this, my phone isn't connecting to any wifi (even those that it was able). I did a factory reset and he doesn't detect the networks.
I though I had the same issue with my x10 but editting the file didn't take effect on my phone. Tryed to delete the wpa_supplicant config file, edit it, downloaded various wifi fixers, and nothing seems to work. Could you help me?
Thank you
Hi im a new member to XDA but im not new to the android os universe as ive rooted, flashed, and modified multiple phones including my very own LG GT540.
So the problem ive stumbled upon is Ive flashed the Swiftdroid 2.0 RC3 CM7 Gingerbread 2.3.5 latest version from mur4ik and i love everybit as apsolutely everything works etc etc apart from one thing so far and that is under Wireles & Networks i can turn on the wifi but when go to wifi settings to chose a wifi connection there apear to be no wifi connections available as in no list... at my own house which has an fully function high spect wifi connection ... is there any fix mabey a patch etc? is there anybody else who has stumbled upon this problem?
p.s when i press left menu button in wifi settings, scan & advanced options appear yet when i press scan nothing happens...
Try a factory reset from recovery to see if that works.

Availability?
Are there any WiFi connections available?
Turn off wifi
rename /data/misc/wifi/wpa_supplicant.conf to wpa_supplicant.old (with root explorer for exmpl.)
Turn on wifi
Sometimes that works (android will make a new .conf file)
Thanks mate it worked perfectly and it was so easy to fix i though i was going to have to reflash the whole phone again... Thanks so much man
Hello i have the same problem with ''djsynth''. I rename he file but wifi still not work
it worked perfectly for me man, just change the extension of the file name from .conf to .old and it should most diffinately work... do you have any battery problems with this rom? mine kept fluctuating all over the place and draining ridiculously fast like in 2 hours mostly in screen off/ sleep mode went from 99% to like 30% .... switched back to cyanogen 6.1 what a shame it was trully a great rom but un usable for long term because of the battery ...
Calibrate
Did you calibrate you battery?
Ok over the last couple months my Wifi will randomly connect on its own. I have checked about every setting I can find and checked any new apps installed and cannot find what it turning it on. I have searched through about a dozen threads about this but have not found an answer. I will turn it off and not even 2 seconds later it will turn it on again. Im tired of this. Esspecially at work since the proxy filter blocks a lot of websites/content so i have to keep it on 3g connection.
Any insight or hidden settings to make it only turn on when I manually connect (yeah i know....)
I am running on the R2D2 2.3.3 version (2nd to last firmware update)
FXR
I fixed that on my CM7 D2 by using FXR WiFi Repair. Don't forget to reboot.
I'm pretty sure that's what fixed it, but at the same time I used Startup Manager to turn off a bunch of stuff that may have somehow made a request for WiFi. iHeart Radio and stuff like that.
It will delete all your hotspots...

Hi everyone,
Since Friday my phone just stopped connecting to Wi-Fi networks. When it tries to connect it says "Network access denied". Mobile data and everything else work fine. I can technically connect if I literally put the phone on top of my router but even then it is unusable. Take two steps away from it and the connection drops. I spent the whole weekend and yesterday looking for a solution. I tried almost everything including resetting the phone, updating the phone from the current version to the B524 beta and back (rollback wiped my phone but I don't mind), the airplane mode trick and countless router rebootings. I really hope it's not a hardware issue, I've only had the phone for a couple of months... To make matters worse I ran out of data allowance and have to wait until next month for it to come back.
So yeah, kind of an annoying situation. Anyone know what is happening?
Thanks.
Have you already tried to connect to other wifi network, problem could also be in your router ...

I did, yes. I've tried to connect to mine, my brother's and some unsecured one that was near me.
if you are rooted then i suggest full wipe in twrp , download new rom and see if it works again , if not it must be the phone who has hardware problem.... and repair shop is needed
I have the same problem, my P8 Lite Wi-Fi just stopped working, tried several different Routers that used to work but just get Network Access Denied. Think this must be a software problem.
Hey !!! anyone get this solution will please help me i am facing same problem "Network access denied"
tried also Install New Rom but nothing will happen ... ???
Hey.
Im having same problem...visually everything works (not greyd out), but when scanning, scans for a second and then thats it. Tried wifi direct, doesnt work.
Also bluetooth doesnt work (same as wifi...cant find nothing).
Tried all those "tricks" what i could find on google, tried all rom builds, rooted-unrooted...nothing works so far.
