No 1000baseT

[milessabin]

I have an N5200Roustor (firmware 1.00.10) with a gigabit capable workstation directly connected to the LAN side of the N5200 (ie. the switch) via cat5e. ethtool on the NAS reports only 100Mb/s,

root@kripke:~# /img/bin/ethtool eth1
Settings for eth1:

whereas the workstation reports 1000Mb/s (this is an Intel gigabit NIC with the Linux e1000 driver),

root@frege:miles# ethtool eth0

Running iperf shows that the real network performance corresponds to 100Mb/s rather than gigabit,

miles@frege:~$ iperf -c kripke

Client connecting to kripke, TCP port 5001

I have tried using ethtool on the N5200 to force selection of 1000Mb/s but without success.

How can I fix this problem?

Cheers,

Dear Sir,

We could via following simple way to verify N5200 network conneciton at 1000Mbps.
1. Confirm the netwrok cable afford the 1000Mbps.
2. Link to cable between Windows PC & N5200, and than we could check the speed from network status.
or
3. Connect to a 1000Mbps switch hub and verify the network speed LED status.

If N5200 can't act as 1000Mbps, please contact with your reseller for RMA service.

Yvon.

seconded: just changed an original cable to "E220470 26AWG 7x0.16 STP PATCH CORD CMR UL C-UL CAT.5e Verified For Gigabit Ethernet" and Network Connection speed dropped from 1Gbps to 100 Mbps, and read/write speed from ~38MB/s to ~10MB/s

I've upgraded my N5200BR to firmware 2.00.04 and replaced the cable with a new length of cat 6 and I still only see 100Mbps at the N5200BR end,

Nb. this is the switch side of the N5200 router model.

Do you have any suggestions for other things I could try?

Cheers,

Funny, I have a 100MB/s and it shows up as 1000MB/S
