Duet not connecting via Ethernet

big_plotter_man

Hi,

One of my MB6HCs is no longer connecting to the internet over ethernet.

I have 3 Duet MB6HCs, each running a large plotter machine. For connectivity, each board is connected to an Ethernet switcher which is then connected to a Wifi range extender. This setup has worked great for a couple months but one of my Duets no longer connects to the internet.

The machine appears to still think it's connected as entering M552 returns this response:

Ethernet is enabled, configured IP address: 0.0.0.0, actual IP address: 192.168.1.119

But going to the IP address listed either returns ERR_CONNECTION_TIMED_OUT on my browser or the web interface will work properly for around 2 minutes before disconnecting and never reconnecting.

If I enter M122, I get this:

I've already attempted to fix this by:

Updating the firmware
Restarting the machine
Swapping the Ethernet cable
Swapping the port on the Switcher

Nothing has worked at the moment. The other two Duet boards still connect to the internet just fine.

Does anybody have any idea what could possibly be wrong?

@big_plotter_man said in Duet not connecting via Ethernet:

M552 I1 S0 ; start WiFi module
M552 I1 S1 ; connect WiFi module

can you try without these 2 lines in your config?

Hi, this appears to have fixed the issue, thanks.
