check the connection status to see if the computer is getting an IP address from the router, if you are using the defaults then the address should be within the following range: 192.168.0.100 - 192.168.0.199
If you are getting an IP, then check to see if you are getting a gateway, default is 192.168.0.1
Not getting an IP or the connection dropping could be the auto channel feature. The router monitors
the best frequency and jumps on it, and can jump again causing this to occur. Try setting the channel
to either 1, 6, 11
