Gigabit network but not quite gigabit

post #1 of 2
Thread Starter 
So I am assembling a gigabit network with a fileshare pc but when I have the fileshare PC connected it limits the speed to 100Mbps. I have the fileserver in the back room and two computers and a printer in the front room. The front room has a Dlink gigabit switch with LED's that show either 100 or 1000 and is working fine after I tested each port for gigabit. The netgear router I have in the back is working fine after testing that for gigabit plus it is brand new.

Currently it looks like this

Fios > Netgear router
| |> File server computer
|> Through wall to switch in other room

Switch
| | |>Gigabit computer
| |>Computer non gigabit
|>printer

For some reason the Netgear router only talks in 100 and the computers try to transfer documents at ~16Kb/s which is ridiculous. Fios isn't gigabit speeds by a long shot but could it be the culprit? I have gotten the computers to both connect at 1Gbps full duplex by hooking everything up to the switch and not using the router but that even limited the transfer rates to 16Kbps which doesnt make sense. Both motherboards in the PC's are full gigabit and one is the Gigabyte GA-A75m D2H and the other is an ASrock board.

Any ideas why it wouldn't operate at full speed is needed. I'm at a loss on why it's not working and I'm guessing it might be something simple.

Does it say that interfaces are operating at gigabit speeds on both ends?
Try to use iperf on both computers to measure the speed between them.
