I have a Wireless Huawei HG520b Router and a Toshiba Satellite laptop. They can connect fine via ethernet, and the router has a connection to the internet no problem.
But if I try to connect the laptop to the router wirelessly it can only get a connection to the router, not though to the internet. "Local access only"
What's more, if I ping the router when connected it fails with "Request timed out" or "no path to host", nor can access its http page on a 192.168 address.
From the router side of things the router assigns a DHCP lease then nothing.
Turning encryption off solves all this but leaves the system open.
The problem appears not to be on the router's side as the laptop I'm writing on can connect via WEP and WPA.
The laptop has connected to a WPA2 network before, so the card can handle it.
