I've been having strange issues after upgrading to .893, and subsequently .901. On .883 my Bionic would find and connect to Wifi VERY quickly, like within 5-10 seconds. Now I'm having to wait up to 30 seconds or more for it to even give me a list of Wifi networks available. This is incredibly annoying!! I first noticed the issue on .893. The update to .901 has not changed the behavior.
Often times it just says "Scanning" and gets stuck there for a long time, as if it's struggling to scan for networks. I didn't have this problem on .883. The only modifications I have performed are being rooted and using root programs.
I tried a factory reset on .893, then a revert to .883 using the Forever Root program. Wifi was very quick on .883 once again, but after going back up to .893, it was slow to connect. So I've narrowed it down to that I believe.
EDIT: Running Wifi Analyzer kicks in and connects Wifi immediately, but only if I run it. What the heck?
