We had someone setup our office network and our internet keeps dropping connection. We have the internet connected to the linksys router w/wireless disabled, from the router to a switch to a poweredge 840 server w/one NIC card and the other switch ports to about 12 PCs. The router has been left w/the IP 192.168.1.1, the server is set as 192.168.1.1. The workstations we have set to obtain an IP address automatically and obtain DNS automatically. It works fine, then all of a sudden the internet connections will drop completely. If we reset the router (unplug and plug back in) it comes back up. Does anyone know exactly how we should have the settings on the workstations? Should we manually assign IP addresses or settings? I saw a post regarding setting the default gateways on the workstations but would the gateway be set only and the other fields left blank and the DNS set to automatci or ?? Many thanks
