I recently purchaced a linksys 802.11g Wireless Router, and I hooked it up to my main computer. I installed a wireless card in my sons computer which is not that far away from the main computer, and he gets good signal strength and a good speed, but every 10 mins or so he gets disconnected from the internet. The icon still says that he is connected, but the internet load, then in a couple mins it will come back on on its own. Anyone have any ideas of what could be causing this?
