I'm in the same boat as everybody else. I've been really frustrated with this issue. Initially, everything went downhill when I installed Adblock Plus from the repositories. Upon further reading, it wasn't supposed to be touched. MicroB starting acting up and wouldn't load web pages and would just sit there. I uninstalled Adblock then.

Thinking MicroB would go back to normal after a couple of reboots produced no results and was still messing up. Upon further surveillance, I found out that I had been dropping connection, which would explain some complaints I had from my Skype contacts and that I would appear online and would go offline. I've got The One Ring installed and my texts weren't going through either and my AP news widget wouldn't refresh properly.

Now I've tried changing my power saving settings and havn't had a dropped connection since. But, it has been sucking my battery dry. Any ideas?
