One thing you may or may not have noticed after flashing one of the Jelly Bean builds for your phone yesterday was that the WiFi performance seemed to be lacking a little bit (for example, when JB is flashed onto the Verizon Galaxy Nexus). Places where you would normally have a full signal were only coming up as a few bars instead. XDA member mwalt2 had enough and found the resulting different WiFi file in his Ice Cream Sandwich ROM, applied it to Jelly Bean and voila! WiFi that’s back up and running at top speed.
After downloading, the file can be flashed through ClockworkMod Recovery and while mwalt2 suggests a cache wipe may be needed, many people are reporting that a straight install works as well. It’s always good to make a back up!
