I have a question regarding a router to a switch. I currently have my modem connected to my router using the uplink port from the router and a patch cable. My question is do I have to use a crossover cable now to connect the switch to the router? I looked on the switch but I don't see any uplink port on it.
I had the network all setup, and one day my cable company came to change our cable modem because we changed from a dynamic IP to a static IP address. I don't know if anyone touched any of the wires, but ever since he came when I have everything plugged in to the network all the lights on the router and switch blink all at the same time, and my network either slows down or crashes.
The only way I found around this issue is to directly connect to the modem that the cable company sent us then the internet works just on that one computer.
Thank you for your help,
