There maybe times when you need advanced stats from your router. These include the sync rate, attenuation and noise margin.
On the Belkin F5D7633, they're very easily to find within the web interface.
Firstly, login to your router via the web-browser. The default IP for the router is 192.168.2.1 unless changed in which case you'll need to use the IP address configured.
Once logged in, you'll find the stats on the opening page.
