I have a Galaxy S3 and a data plan.
I prefer using wifi whenever possible.
I tried to connect to a few networks, both private and public but I always get the same result: phone will say "connecting..." or "obtaining IP address..." without actually connecting.
Restarting the phone won't work. Simply restarting wifi won't work.
A filtered log of "WiFi" is available here. I used LogCat for it. I also tried to disalbe DroidWall but didn't help. I don't remember what I have done before this occurred. Last option would be formatting phone and restoring TitaniumBackup
Any idea on how to connect again to home and other networks?
[Edit] It looks like the device connects only to one or few networks.
I have a
Vodafone Station 2 router at home. I usually keep the built-in wifi disabled. When I enabled it, I was able to connect the phone to it.
I thought this could have been related to the installation of the Vodafone Station 2 app on the very beginning. My suspects become clear when the device is able to connect only to a Vodafone-xxx network but I have wiped the device. I have tried to connect the device during Android configuration without success.
[Edit] This suggests to me that it's a hardware problem. After upgrading to stock 4.1.2 I don't get the same error as before (good news) but instead it repeatedly refuses the WPA2 password for the home network. To be precise: I did the
Vodafone-test only after upgrading ROM.
The Vodafone Station 2 router features wifi 802.11 a/b/g/n where my plain old home router only supports b/g. I have tried to configure Station for b only just to see if the device stopped connecting. I have no means of stripping
Vodafone prefix from SSID in VS2 router
[Edit] Anyway I have another log. I don't want to separate myself from my device for too long. I'll try to install the stockest ROM for GS3 and to update via OTA.
02-26 20:30:03.880 E/WifiHW (17931): Unable to open connection to supplicant on "/data/misc/wifi/sockets/p2p0": Connection refused
But I'm not using Wifi Direct!!!!!!!!!!
[Edit] notable line after reverting to oldest stock ROM
I/wpa_supplicant( 6982): CTRL-EVENT-ASSOC-REJECT bssid=2C.DA.82 status_code=16
[Edit] striked the Vodafone part. Simply the phone connects to the router if you are a few centimetres from it. If you get past about a metre's treshold the phone won't connect. This seems to be a widespread problem affecting Samsung devices, especially Nexus for what I have seen so far.
