Hey All,

 

How do I determine what my NIC on my NAS machine is connected to my router at speed wise?  It should be 1 GB but each computer seems to max out at 100MB even though the windows Machines say they are connected to my router at 1 GB.

 

Thanks!

If it isunRAID you are referring to as your NAS, type

ethtool eth0

Thanks Joe.  That did the trick.

 

Oddly it says I am connected at 1GB which is odd since I can't seem to get past 100MB while copying to the machine.

The only way I know is to look up the manufacturer's specification for the hardware and compare with the specification for the drivers supplied with the Operating System.

Using manufacture-specific unix commands you can find out the current configuration (if there is one) of each Ethernet card but not the full capabilities.

Thanks Joe.  That did the trick.

Are you confusing Gigabit (Gb) for Gigabyte (GB)?  1 Gigabit is equal to 128 Megabytes.  Routers and switches measure transfers in bits and not bytes, I assume that you have a Gigabit NIC and Router/Switch.  With a gigabit NIC I would expect to see about 100 MB/s.

I just had a look at this and I am not sure how to read it, as when I do data tranfers I am only getting wound 10mb/s on a 1GB card.

so can someone please inform me if my card is set to 1GB and if not then how to set it. as I have a 1GB network and it would be nice to send data the Max speed.

This shows the supported speeds, including gigabit.

But this shows it's only linking at 100Mbits, try a different cable or switch/port.

 

the cable I am using is Cat6 and the switch is a Netgear GS108 and it is plug into the 6th port.

looking it at it only has one light. so I have moved it to a different port and this also gives me one light, so it looks like a drive / nic settings issue.

if this is the case then is there a easy way to set the nic to 1GB ?

The NIC should auto-link at the max supported speed, if it's not the cable/port it could be a switch or NIC problem.

update: I just found the following command  ethtool -s eth0 speed 1000 duplex full autoneg off    which course my unraid to pull over.

but after a few reboots, I am happy to report that I now have the follow.

Forcing it may not work as intended, be sure to check with iperf.
