I'm having some problems with my LinkSys router; whenever I am using it on the network, all of the PCs have "limited or no connectivity." For a little while, the PC I'm currently on was working fine on the network while the two others were failing, but it has failed also and is now hooked directly to the modem. I've tried resetting the TCP/IP and DHCP, but no luck. When I plug the modem cable to the router, it reads the internet as working and it notices the PCs that are connected to it. However, I cannot access configuration settings by going to 192.168.1.1. I don't understand, and don't know what to do.
Two of the PCs are connected by cable, and one is wireless. Prior to all of this, the wireless one was experiencing connection issues. There was also the instance of an IP clash, so I disabled the router's DHCP services in hopes that each client would lease an IP from a regular DHCP server. I don't know if this is the source of this error, but I'd like to re-access the modem and change it back, so at least 2 of three PCs can access.
