For years, my home network has been held together by a single wired router, a 4-port Linksys. Today I swapped it out for a used 8-port Linksys--same basic model, just more ports. Each computer can see the other computers (3 PCs and 1 Mac), but no computer can reach the Internet. With the 4-port, I could (can) log in to the router, using "admin" for both the username and password. That would get me into this configuration screen, and I was home free. Well, "admin" doesn't work on the new router. Did the previous owner burn a new username and password into its ROM? I've pressed the router's Reset button, figuring that doing so would let me reach the configuration screen without a password or username. It didn't. Maybe I didn't press Reset the right way or the right time, or didn't hold it in long enough. Any suggestions before my family burns me at the stake?
