[solved] Gigabit box (Technomate TM-NANO 2) connects at 100Mb

[balanga]

I have a Technomate TM-NANO 2 box which is supposed to connect at 1Gb, but only connects at 100Mb. All the rest of the devices on my network connect at 1Gb.

Any idea why my box does not? Are there any settings I can adjust?

Hello.

You can to try the following commands in the Shell / command-line (Telnet or SSH), for retreive some info about NIC link-speed:

Code: Alles auswählen

ethtool eth0
cat /sys/class/net/eth0/speed
dmesg | grep eth0

This is probably caused by a universal inappropriate driver for the NIC. But try these commands first.

So the link partner (which is your box connected to?) does not advertise more than 100mBit modes.

The problem could be in "autonegotiation" (i.e., automatic link-speed recognition, duplex, crossover, etc.). Since you write that other devices work at 1 Gbps, then the failure is somewhere in the automatic recognize link-speed (a typical error). Try to change the speed and then test the data transfer rate (for example via an FTP connection):

Code: Alles auswählen

ethtool -s eth0 speed 1000 duplex full autoneg off

Turning off "autonegotiation" at 1000 Mbps line speed will probably not work (due to the standard). So then try this:

Code: Alles auswählen

ethtool -s eth0 speed 1000 duplex full autoneg on

If this works, there is a neccessary to change the network configuration somewhere in system configuration ... or make a custom startup bash-script to change the configuration during booting your Enigma.

Further to the info provided, I changed the network cable and now it's working at 1Gb as it should.

Many thanks for the help.

So the link partner did more sensitive tests to the cable, and decided, only to advertise only 100mBit. Fine, that you could find the wrong component in your environment. Have fun.
