Default [Q] att dn3 v4 beta 4.4 question about signal

Hi everyone. I currently have the note 2 att dn3 v4 beta rom installed. My signal is constantly jumping from 4g to h+ on a daily basis every 30 min or so. The internet seems to also glitch a lot. I always have to exit and reopen the browser in order to finish loading the page. Anyone have any solutions or possibly experiencing the same problem as me?
