Javascript error
My new power supply has of yet not showed up but now I am starting to get a constant Javascript error
that says that it has closed the connection to my board and if it happens again I should contact the author and share the error message. Should I start a new thread? Can all of this have something to do with the web UI?
Here is a screenshot of the error:

There seems to be in fact some grounding issue. I will order a new power supply (Was planning that upgrade anyway since I've had the same crappy one since 2014, will get a 24v Mean Well while I'm at it)

Will update when it arrives and verify that it solved the issue.

Thank you so much for the help!

@veti Thanks, will try that! (having problems as of this moment, so I will get right to it!)

@veti No hub.
I know, that's why it is a bit "weird", also it does not matter if the Duet is powered off or on after I start experiencing the connection problems with the board, as long as the ethernet cable is physically attached to the board and to the switch the whole network gets unstable but when I unplug the (powered off or on) Duet, the network is fine again.

What's extra frustrating is that I can't seem to reproduce the errors at will, it truly is random, the only constant is that:

a) When it works it does so indefinetly
b) When it doesn't it effects my entire network even if the Duet is powered off but the cable is still attached

Could there be some sort of short or loose connection on the ethernet connector on the Duet?

I know ,there are several threads similar to this one but after reading (as far as I can tell) ALL of them without finding a solution, I make a desperate attempt to get some help figuring this out...

Problem:
Ever since I got my board I have had seemingly random problems with my ethernet connection. When it works it works perfectly but next time I power up my board I may get constant connection errors. Each "session" may last for 5 to 30 (tops) seconds.

Sending 100 pings gets about 30-40% lost packets.

Upgraded both firmware and Web, tried different SD-cards, tried 6 different ethernet cables (both shielded and non shielded) Tried two different routers (consumer grade) and one of my Cisco switches and a Cisco router (had them laying around since my time as a network admin)

Tried different network settings, dhcp and static makes no difference. Setting MAC on the board changes nothing, no conflicting IP's on my network.

Makes no difference if I am connected using USB and no 12v or no USB and only 12v.

WHEN it works and I just leave the printer on it works forever (but sometimes, after 10 days or so I might have to power down, not for connection issues but rather because it's pretty annoying to hear the fans 24/7 for 10 consecutive days when not printing JUST so that I won't loose my ethernet connection...

Web browser gives me either connection timout, host unreachable or connection_refused

Weird fact:
When having said connections issues with the Duet, it always effects the rest of the network, when pinging my router 100 pings I get around 15% packet loss and response times varying from 2-200ms

Any help?
