5G Router - Local Domain Name restriction?

[Vocoder]

Trying to set a simple, one-word local domain name but seem to get errors unless I include a special character.  Specifically,  "house.lan' works. 'house" or "lan" do not. 

Anyone know how to get around this? Thanks!

I don't think there's a workaround. It won't let you get around using standard domain naming conventions. For example, the default the Verizon 5G Home Internet routers use is: mynetworksettings.com
