[Q] WiFi issue (unable to scan networks)

---

Hello every body...
when I turn on the WI-FI the massage appear Unable to Scan Networks Then the wi-fi turns itself off.
Help me please guys...

i would suggest reflashing the stock firmware with ODIN. I had an issue like this on my Nexus One. Nothing helped. I had to fully wipe the phone and start over.

I found it :
since you're rooted, go to /data/wifi/ and delete bcm_supp.conf (back it up first just in case). Then reboot your phone.

Awesome! Many thanks for the tip! You've made my day! That file's gotta be deleted from time to time, as it can get quite clogged. (And when you think I could've re-flashed my phone as per the previous post...!)

I having the same problem as this. after i removed and re entered my wifi login. also i had been on holiday and logged into a few other wifi routers.

when i re entered my home wifi it just kept turning off and saying "unable to scan networks"

its a vodafone UK contract Galaxy S (if that makes any difference)

I tried to root my phone using

[PROGRAM] One Click Root/UnRoot I9000 (Eclair and Froyo) Mac and PC

it seemed to work . i had an extra app for changing a few settings. but i still couldn't find the wifi file i need to delete? Had it not been rooted properly?

I'd really like to fix this without having to do a master reset every time?

What are my options?

Could i take an image of the mobile and remove the file from the image? then restore the image. A bit crazy if routing is not a possibility?

Can anyone help?

Thank you, unable to scan networks solved

How did you solve it?

with master reset?

Latest update to DI07 fixed this issue for me

The update was DI07 for the Samsung Epic 4G, not the Vibrant.

Previously I read that a factory reset would fix this problem but I held out for the new update to be pushed to my phone today (9/19) and indeed it fixed my problem. After the update rebooted, my Wifi turned on with no problem and it showed my previously added networks as well.

Good luck!

Is this update for the galaxy S?

or is there going to be a similar update?

I haven't logged onto another WIFI since I had to reset the phone (apart from my home WIFI). so i don't have to go through setting it up again.

cheers for the extra info

quick update

I am backing up with titanium backup manger now (free)
so hopefully it will restore the wifi it goes wrong again
(the phone needs to be ROOTED for the Titanium backup to work)

I rooted my phone with

http://forum.xda-developers.com/showthread.php?t=742403

one click rooter ( i couldn't run the "Galaxy S I9000 One-Click Root" file. i ran "rootme" file for 2.1 android, the rootme2.2 is for 2.2 it says dont run both)

And have 'astro file manager'(Free) and can explore more of my phone by pressing the up button a few times.

in astro file manger I searched for the word 'wifi' and got about 3 results. So its probably one of these.

We'll it working for the moment but I'm posting the more info for anyone else.

(I still don't know which file to delete to reset the wifi though.) but the titanium backup should be able to restore the wifi settings
