Thankfully, I never had an issue with this particular problem when I updated my original Droid Razr; however, when I updated my mom's phone a couple of days ago to Jelly Bean, her wi-fi didn't want to connect to our wireless and it couldn't even find the SSID.
I, of course, went on forums, including this one, to try and see if there was a fix for it. Sadly, there didn't seem to be. I knew it wasn't our router (I was connected to wi-fi) on my phone and our router is new and not on the list of problematic devices.
Until I could find a solution, I decided to turn off her 4G-LTE to save her battery using *#*#4636#*#*.
Because I am a curious creature, after switching to 3G, I decided to go into her wireless settings and try to connect to our network again....this time with success.
As far as I can tell, the Jelly Bean software update might have caused an error between the 4G and the wi-fi (the 4G forcing the wi-fi out and away and unable to connect as it were). After 10 minutes, mom's still connected to the wireless in the house.
