And use cox cable. I just bought a new net book and it is close to the router. When
Click wireless net work connections are show all connections it will not connect

It is just trying to get the internet on to the net book. Please help if you can

What security mode:

WEP (bad choice)
WPA-PSK (getting better)
WPA2-PSK

WPA2-PSK

Also, what model of router, what wireless network adapter and brand/model of netbook? I'm curious, have you tried unplugging the power from the router and plugging it back in again? Also, when you are trying to connect to the network, are you specifying the correct security type? Open, shared, wep, wpa/wpa2?
