Hello, I am a new member of this forum and first off would like to thank the owners because this is a very helpful site. Second, I have a Dell PowerEdge server running on Verizon Business DSL. I have it networked through a switch to the router and 3 client computers are on the switch as well. My issue is that everything works fine for about two hours, then the port starts blinking on the switch that is connected to the router. First I thought it was a mechanical error with the switch so I went and purchased a new one, but after I bought my new one the same error occured where the port was blinking, this was a differnt brand than the first one. Is the server possibally interfering? Why, and how to I resolve this issue? Thanks !
