I may have a stupid question or a bad router. I have a wireless router that was purchased in 2006 and connected to an existing router. It worked okay, until I tried to enable the WEP security on it. Then it started dropping connections and locking me out so that I couldn't access it anymore without resetting it by using the pin-switch. It was a gimmick, so I eventually stopped using it. Now I want to reinstall it. I set it up with WPA security, and connected it to the main router in a daisy-chain configuration. The lights show ready, the wireless router insists that the Internet connection is good, and it shows the IP address of the main router as the gateway. The trouble is... I can't do anything from there. I have no Internet connection, I can't see the other machines on the wired network, and although I can authenticate wirelessly, I also can't do anything from the wireless connection. I can access the main router, but I can't get out and nobody else on the main network can see the wireless router. I have tried different IP configurations, disabled the DHCP server, and tried other things that I remembered to do when confronted with a network problem. Nothing worked. Then it got worse. I just tried to get back into the router by connecting to it through an Ethernet cable again and was locked out. I had to reset the router to get back in, and it still doesn't work. Am I missing something obvious here, or is my router bad? I'd say that it's bad, considering that it's blocking me from accessing its configuration screen.
