Internet Connection Troubles?

[jct101]

Is your internet connection working? Did you check it with another machine. If not then do so and call your ISP.

It sounds like you hit everything. You may want to eliminate anything between you and your modem (hubs, switches, routers) and use a different ethernet cable. Sometimes the cables become damaged (not that frequent). More often small shorts will occur in the modems. You may wish to swap receptacle the modem is connected to for power to one on another circuit.

Other than that you might want to just create a new admin account and try setting up access from there. Put as much data as you can in your local settings and on the premise equipment.
