I have more wired ethernet devices than there are ports on my Archer VR2800 so I have used it with a switch connected to one of the VR2800 ports, and the surplus devices connected to the switch.
This was working fine for the first six months or so but now all the devices on the switch are offline and do not show up on the network.
I searched the forum and found someone else with a similar issue who said that replacing the cable between the VR2800 and the switch with a crossover cable solved the problem for them, so I bought a crossover cable and have connected this now but this has made no difference.
Is there anything I need to configure on the VR2800 to tell it I have connected a switch to that port? Or a particular port on the VR2800 that I should be using to connect a switch to it?
If anyone has any other ideas to try to resolve this please let me know. I guess "buy a new switch and swap that out" is going to be the next step if no-one has any suggestions relating to the VR2800, but I hope the switch hasn't died after only six months' use. (All the switch's lights still come on and flicker as normal by the way.)
