Do you mean you want to restore the Netgear wireless router back to the factory defaults?
If so then :-
Power up the Netgear wireless router and use a sharp point and
press and hold the RESET button on the back of the router until the LEDs flash then release the button.
Then connect a LAN cable from the computer to the Netgear wireless router, then open IE browser and enter the configuration IP address, login and configure the wireless settings ie. SSID, encryption etc.
Take a note of these settings and configure the wireless cards in the computers with the router's settings.
Remove the LAN cable, the computers will now communicate with the wireless router.

is that wired connection or wireless? if it is wired, checked the cable and the port, make sure that the LAN connection is enabled.

if it is for wireless, checked the wireless settings of the router, enable the wireless card of the wireless computer and, verify the wireless settings of the netgear adapter and from there connect to it.

Arunk, When you say the electrical characteristics of the new A/C adaptor are the same as the old one did you check to ensure the amperage and the polarity of the power plug is the same as well?
