OMFG-here is the answer for EVERYONE and why the netgear for my computer would work wireless but not on a computer previously connected to the same router. I thought my friend could get things going after my modem crashed and I had to buy a new one. Apparently, my IP and DNS settings were changed somewhere in the process and I was TWO days without he computer connected via Ethernet cord. This is the LIFESAVER of all time. Paragraph three is what truly fixed my computer problem. Two check marks in the wrong box caused more than 50 hours of frustration. GOOD LUCK ALL.
to access the set-up page of your router ( http://192.168.1.1 ) , push the reset button of your router at the back for about 10 sec., then make sure the PC is connected at the LAN ports 1 or 2 or 3 or 4 of your router, then open the browser then type in http://192.168.1.1 ...
if it won't make it... make sure that the internet protocol TCP/IP properties of your PC is set to obtain an IP adress and DNS servers automatically...
go to network connection found under control panel
right click on local area connection, then click on properties
under general tab, highlight internet protocol TCP/IP , then click properties
then make sure it's set to obtain an IP adress and DNS servers automatically.. click "ok" and click "close" button for the windows opened
try opening the router's set-up page again, it should open already, if not, reset the router again and reboot your PC...
Many thanks for your help
