I am running into the same issue since I updated my network hardware with a UniFi UCG. What specific settings did you have to adjust?
Evening, apologies for slow response. I havenāt set up any VLANs, I might yet but didnāt see the need at the time and as everything worksā¦ā¦.The photo is my Network settings page
Thanks and no reason to apologize!
Unfortunately, my settings look somewhat different:
Anything there that pops into your mind I should change? Homey is still down and hasnāt reconnected yet.
You might consider changing āDomain Nameā to home.arpa
Donāt use made up names
thanks - will try later today when I am home - I am not exactly sure it I need to replace localdomain with home.arpa or a variant like *.home.arpa, and I donĀ“t want to break my wifeās internet access while not at homeā¦ 
IĀ“ve setup a VLAN for the Chinese mow robots, and the domain name is empty there. Question: Fill in the same name as for the default network or leave blank?
