I play with a mate who is also in the UK, and i get alot of Lag and connection issues, a good handful of the time its fine, but twice now when im on the last round of the Arena of t2, everything locks up, and even if i close the client to reconnect, it has issues with connecting!

No its not a firewall, no its not my computer and no its not my connection! I play lots of other online games with No issues, its happend to my friend also hat some moments! what exactly could be causing this? we also use the same provider!
