WIFI not working after 4.3 sideload

[chillviper123]

I sideloaded the 4.3 update onto my N4 and thought everything was working fine. Today, I notice that it's not connecting to my home network. I rebooted the phone and my routers and no go. It says "out of range" or when it sees it it says "saved/Secured with ..." or "Authentication Problem." Any ideas?

Try forgetting the access point and then re-establishing it. Does this happen with only your home network, or does your phone refuse to connect to any wifi?

I forgot both my home networks (2G and 5G) and no go. Will have to see if it works at my work wifi today.

See if there's a firmware update for your router if your work wifi works fine. I know some people had issues with some routers at the release of 4.2 back in the fall, too, and a firmware update (when available) fixed many problems.

Apple Airport Extremes are up to date. The fact that it jump between Excellent strength and Not in Range when I am 5 feet away is worrisome. Must be something wonky with the radio software. It worked perfectly prior to the 4.3 sideload. May have to flash it with the factory image.

UPDATE:

My N4 works fine on my office wifi network. I have two Apple Airport Extremes at home - one for 2.4G G devices and one for 5G N devices. The N4 works fine on my 2.4G 802.11 G network. It's the 5G 802.11 N network that keeps bouncing from not in range to not being able to connect to it. It just flips to Saved, Secured with WPA2 and never authenticates with it.
