Force speed and duplex

(1/1)

antunafr:
Hello everybody, this is my first post. First of all, thanks the Wanos team for the great job.

I'm setting up a Wanos 300 appliance and I need to force speed and duplex of my WAN interface to 100/full.
I have not found where I can do that at the web interface. Maybe it is not possible ?

Could anyone explain me which is the preferred way to modify speed and duplex settings on a Wanos appliance ?
The software version is 3.2.3 Prod.

Thank you very much in advance.

Regards.

The interfaces are auto-negotiated by default. The recommendation is to try as far as possible to use auto and enable auto negotiation on the switch/router side so that negotiation succeeds.

For the corner cases, when the recommended method is not possible, here is how to set it manually:


--- Quote ---ethtool -s wan0 speed 100 duplex full
ethtool -s lan0 speed 100 duplex full
--- End quote ---


Once you are happy that the commands work as expected and you want the commands to run automatically after reboots etc, then add them to /etc/wanos/ethtool_options file e.g.:


--- Quote ---ETHTOOL_OPTS_WAN0=speed 100 duplex full autoneg off
--- End quote ---


We'll usually do something like this for the client remotely, but you can run them, just make absolutely sure there aren't typos in the line.

Hi ahenning,

Thank you very much. That's exactly what I need.

In fact, for your information, I can't use autonegociation because my WAN interface is connected to a telecom operator device and I can't change its configuration.

Thank you again.

Regards.
