iChat Network Disconnect

I have a linksys wireless router at my house, and it has been working fine since i've been back from school. however, I noticed every so often, it would kick me and everyone in the house off the internet, totally disrupting the connection.

I later found that this only happened when I opened iChat. I can use yahoo messenger, and the internet just fine but as soon as I open iChat it knocks everything off.

This works also without the wireless connection, when i connect directly with an ethernet cable..

I haven't been able to find any other forums concerning this problem, does anyone know anything about this problem?????

any input would be greatly appreciated
