Hello, I just noticed by checking my Unifi that I have a virtual machine running on my network and that constantly changes its IP address. It started exactly the day I first connected the RTK to my network via the RJ45 cable ;-( it constantly changes its MAC address and the xx:xx in the title is the…

I’m only seeing two devices. Hostnames are CH9121 and YARBO

ave you read your dhcp offline connection ? this connection connect and change everytime ! or I m crazy lol :wink:

I’m not seeing anything unusual in the recently connected devices. You’re post does sound like there’s a crypto currency miner running on something.

My Unifi Router identifies two devices. One it identifies as an “Intel NUC D34010WY”. And the other as a “3CX PBX Virtual Server” (hostname Yarbo).

I have Unifi as well on my network, DreamMachine for router and just installed Yarbo yesterday. Unifi DM named the hostname YARBO and the manufacture is Promax if that helps you out at all.

As Bryan pointed to above the dc does do multiple MAC addresses. I have a Yarbo at a tech college and their switches do not like this activity and we have to cycle the port manually to get the dc going again. I have had a video meeting with a Yarbo tech about a month ago and he said it is a known is…

I’m sure this is a really hard one to nail down what the exact root cause is. Hopefully they were able to identify something with you and have the fix in the pipeline.

The IT guy at the college is good with this stuff. He logged the port for a month or so to see the issue happen many times. He turned off all the security on the port but we still kept seeing loss of Halo, sometimes once a day, sometimes once a week. I just have to keep checking the app. I now have …

So strange. I hardly ever have to reset my DC’s. I do have periodic HaLow signal strength decreases but for the most part it just works. Even if HaLow signal is poor, it just fails over to cellular seamlessly for me. I think we’ve discussed this before but my memory is terrible. How close is you…
