I experienced the same WIFI problems after updating to Jellybean. I have resolved this issue and my WIFI is working without any connection problems. The Jellybean update is not compatible with all 802.11 Standards. My Actiontec wireless router only supported 802.11 G. This is the problem with this upgrade. I have upgraded my network to a ActiontecGT784-WN This DSL Wireless router will support 802.11 B, 802.11 G, and 802.11 N The Jellybean upgrade apparently doesn't support 802.11 G So much for backward compatibility! I wasn't going to wait until the next OS fix to correct this Issue. I have read and tried several of the so called "Fixes" for this issue in this forum. None have worked, which led me to investigate further concerning the WIFI compatibility issue, which was the whole issue all along. Hope this Information is helpful. I am running the Jellybean version of Android on a Verizon Razor Maxx.
