I have recently changed my wireless router from a Linksys WAG2000 to a Wireless WAG 54GS. My main PC is on Win 7, and I have a laptop on Vista 64 bit,and have a USB wireless dongle. Before I changed the router I connected via the dongle with no problem, now I cannot connect, I am sure that I have all the correct passcodes but they all fail. Can I reset these on the router without losing internet connecting? If so how do I do it.
