Crazy Router/Computer Issue

This one is making me nuts.

My Netgear WGR614 Router stopped working on wireless the other day. Still worked fine....just lost the wireless signal.

Ok so I bought a new Netgear WNR3500L yesterday. Set up was easy and I thought all was well. My computer for some reason called it a new network and named it network 3.

The crazy thing is some internet sites will not load. My Hotmail which I access through Windows live mail will not load.( but my normal email works fine). nor will it load going straight to Hotmail ....any site that I have to logo onto will not go any further that the log in page. It's like something is blocking certain sites. Yes, I turned off the fire wall and my anti virus and still the same. My laptop however connected by wireless to the new router, will work perfectly which tells me the router is fine.

I reset up the old router(which now the wireless works) and all is well. My computer calls and did call before all of this just plain network!

Any thoughts? Some setting in the network that I'm missing?

I would have mentioned that resetting the first router would most likely fix the wireless connection problem.

For the second router, it sounds like there may have been a DNS server problem which you should be able to fix by changing the DNS servers in the routers set up page.

Tried that already. Infact I reset the router 3 times and still have the same issue.
