Many users enjoy staying on the cutting edge by flashing a new ROM onto their devices. Verizon Galaxy Nexus owners who tried to flash a recently released Jelly Bean ROM onto their device discovered a problem with wifi connectivity issues. Connection strength could not be maintained.
Fortunately, XDA forum member mwalt2 took some time to dig into the reason and discovered a single file that differed between the Jelly Bean ROM and what Verizon provides. Restoring the Verizon version appears to fix the problem. Follow the source link below for the file and instructions on the fix.
