Lately, ive had issues with the EA app not showing BF3 in my game library. What I had to do was to go into task manager and kill the EAhelper app and restart the EAapp and then everything is fine. I have to do this every few logins now. EAapp is such crap...
Maybe try that?

Thanks to @TakeOverTheWorld for bringing this to light.
At this point switching ISPs is not an option. I just have to deal with it when it happens. I'm not worried about the 100 ping so much. If it was steady it wouldn't be an issue. It's the ping rollercoaster I can't handle when it starts acting up. Lag spikes are a bitch.
Ping plotter basically does this. What I know is that there are a couple of hops in IL that are pretty laggy for me. North of 100ms. Nothing I can do about it I guess.
