DC every 20 minutes

[gianni]

hi, i would like to ask if its normal that i disconnect every 15-20 minutes. its not rly a disconnect, just everything freezes. for example i'm casting renew and he only raises his hands but nothing happens. the only way to stop this is to fully restart my pc! cos when i just try to restart worldofwarcraft it just keeps connecting without results. is this only my problem or are other ppl having the same thing? how could i fix this...
pls answers...

Sounds like a problem with your computer. My old eMac would freeze and I would have to cut the power. But it was old...

Are you behind a firewall or perhaps a router?
