Hi people, I've been browsing the forums for a while and I've tried to piece things together but my direct question should clear it up!
I'm on NTL 600k and I've had no problems... ever! But since 2 weeks ago I get HUGE lag on PC games and my Xbox Live. I simply can't play online games anymore

. Now I've read some things that if I change my DNS server that it can solve things?
Could someone please shed some light on my woes?
Thanks very much for your time,
Elliot.
