The office I work at has 6 wireless computers and 2 wired PC's connected to a Linksys wireless 4 port router. I have WPA2 and Mac address filtering applied on the router and is set as a DHCP server to give out IP addresses.The internet connection is DSL from a local phone company. All the other computers in the office access the internet and network no problem except one of the Gateway laptops running windows XP pro, SP3. For some reason when I am surfing the internet i will receive an error in Firefox saying the connection has timed out. The wireless connection in the bottom right corner will not be crossed out but will stop blinking, indicating it is not sending or receiving packets. It will do this on and off just about ever 2 min. Any ideas on what it could be or what i could do to fix it would be much appreciated. Thanks
