The Express 6110 does not support 100Mps. The unit also does not work on
auto sensing circuits. You will need to set the port connected to the 6110

With this problem/question:
I have a small ethernet network with 10/100 auto detect network cards
connecting to a 10/100 auto detect hub with cat5 cable. I have no trouble
connecting to clients at 100Mps with the network cards set at auto, but I
cannot connect to the 6110 Adtran router that I have connected to the hub.
If I change the network cards to 10Mps then I can connect to the router. Do
I have to configure something in the router?
