Living in the Infinity tower location.
I don't know why it jumps up to 2500ms like that. It's just been patches of high latency followed by patches of incredibly wonderful low latency of around 12ms. I'm not using any peer to peer programs, streaming, loading any videos or music, downloading anything, or uploading anything. I've swapped the wireless settings channel to 1, 6, and 11. Nothing has improved.
Does anybody have a clue to what's going on?
