Please tell me that someone else is having constant lag spikes on Battlefield 3. It's driving me absolutely nuts.

It started about a week ago now, I've tried restarting the router to no effect. It doesn't seem to matter what server I play on within Australia.

Currently staying over at my moms and she isn't bothered to have it sorted since it doesn't affect her. Could I still phone in and beg them to check what is wrong?

Apparently my mom has Telstra clear with a 40GB cap and free international calls, not sure what package that is..

How would I go about solving this?
