Everytime my friend come over to my house he brings his playstation. I go on my laptop to play WoW and he usess the PS3 to play online. For about a couple hours its fine but then it starts to disconnect us every 10-15mins for like 10s? I have a Linksys WRT54G v.8 router. I have contacted linksys several times but everytime turned out to be wrong. Also this problem stops about a day after they leave. Why is this happening and what can i do?
