Cannot connect to internet using Belkin N750 router
I've 3 laptops, 2 android devices, 1 WP7 and 1 desktop at my home. Recently I bought Belkin N750 DB Wireless Dual-Band N+ Router and configured it successfully. I'm able to connect to the network/internet through all of my devices except the desktop. For desktop I'm using Belkin F7D1101v1 Basic Wireless USB Adapter.
Strange thing is that I'm able to connect to the router's network. I can also open router's admin panel(»router/index.html) on the desktop, but i'm not able to ping the other systems or access the internet. I'm not sure that the issue is with my wireless adapter or the router. When I switch back to my old router (DLINK N150) i'm able to connect to the internet through the same wireless adapter.
Can you help me find out where is the issue?
I've already tried resetting factory default settings of the router, but it did not solve the issue.
Thanks in advance.
