i cannot connect to the internet through my main dilink wireless router but i am able to connect through the netgear wireless extender. and this problem started more or less the same time when i got a surface windows 8 rt tablet (which is unable to connect to the extender but connects to the router). question is how do i troubleshoot the issue of not being able to connect to the internet through the router when i use my main computer. thanks in advance.
