Re: c6300 will not connect to internet
> what causes a c6300 router not to connect to the internet
Based on no useful information at all? Too many things to make
trying to list them practical.
C6300[v1] or C6300v2? Look for "Model" on the product label.
Connected to what?
Visit http://netgear.com/support , put in your (actual) model number,
and look for Documentation. Get the User Manual (at least). Read.
Look for the LED descriptions and "Troubleshoot".
