I have tried everything, literally everything, to no avail.
Then, my service supplier pushed an OTA update to ICS 4.0.4 and immediately upon rebooting, I lost the connectivity to my home wifi (which uses WPA). Until 2 weeks ago, I had a motorola razr which was factory running Gingerbread. OK here's something interisting for you guys: Does anyone else have this problem? Has anyone had any luck fixing it? Does anyone have any suggestions? I'm at my wits end, I dont know what else to do. I need to be able to use the 2.4Ghz band. Using 5Ghz is not an option for me though, as the range is quite poor. I am able to connect to the 5Ghz band, but not the 2.4Ghz band. I am able to connect to my parents wifi, and my friends wifi, but not my own, and not at my work (was previously able to prior to upgrading to 4.0.4).Īnother weird thing - my router is dual band - 2.4GHz and 5GHz. The weird thing is, it seems to work on some routers and not others. no security settings) and i STILL get authentication error occurred message. the most bizarre thing is, i turned off my router security (i.e. I have disabled mac address filtering, firewalls etc. My wifi has a WPS function - I also tried using this without any success (no authentication error occurred message - just times out when trying to use the push button or pin technique). I have also tried factory resetting both my phone and my router - no luck. I have tried rebooting my phone, rebooting my router. My router settings have not changed, my password has not changed - all other devices in my household are able to connect to the wifi without any issues. Ever since then, everytime I try to connect to my home wifi, I get the "Authentication Error Occurred" message. Everything was working fine, I was able to connect to my wifi at home no problems. I have a Samsung Galaxy S3 that was originally on firmware 4.0.3 (what was shipped with the device).
