1/ I set the channel on "2" and for some reason every so often my father will attempt to get online using his laptop and he will not be able to get online. Once we goes to settings it shows on another channel (in this case it went to "10") 2/ Also when we go to browse for other connections, the window opens up, then closes after a few seconds. Netgear router, Netgear wireless card. I have MAC Address filtering but no WEP key or anything setup currently. help!
