|In normal cases, when router is configured correctly, you don't have to configure your computers with static ip addresses.|
All informations, that are needed to connect to the router and the internet comes automatically from the router.
So if there is more that one network card installed to your computer, you have to check the settings of all the network cards.
I suggest to set all network cards to optain ip address and DNS server automatically.
Then restart your computer an pray :-)
Please send a reply, if you solved the problem !!!
