We have a small office with 5 computers (one which serves as the file server) and DSL modem networked via an SMC Barricade router. We also have a 10 port network switch connected to the router (for some other stuff including printers and a large outdoor sign that runs public service announcements, etc.).
Our problem is that the computers lose connection with the server and also lose their internet connections. This happens every week or two. I don't think it correlates with any specific event (e.g. power dips/surges/dropouts, etc...) but I can't be too sure about that. The only solution I've found is to turn off the router and then turn it back on.
I don't know much of anything about networking and the network was setup by the former owner. Any help troubleshooting this would be greatly appreciated!
