My internet at this flat sucks:
however even with that sort of connection I would expect to get a stable ping in game unless there is strain on the network. So I get the idea that the only thing I could do to fix that would be to prioritize traffic to my PC.
But we have a pretty crap router: TP-Link TD-W8968.
Is there anything I can do with the pre-installed firmware?
If it's any help: http://puu.sh/ly53N/4e7b0112a7.png
