Help Please

I have been having some problems with being booted from the server. I am playing on my laptop via a router. Typically I can get logged in and play for a while and then all of a sudden I can't perform any commands. I can't attack, talk, anything, but my char can still move around. After a minute or so a box pops up saying I have lost my connection. When I log out my connection to the internet is disabled and I have reconnect ot the internet and then log back into the game. Is there a setting on my wireless internet that could be doing this or a bug? I have tried shuting off my firewall and playing but it still boots me. If you have any advice or know why my router might do this please let me know. I have a Linksys router. Thanks.
