I have two PCs on my local network running Ubuntu. One is running 16.04 and the other is running 18.04.
I was having trouble accessing other devices/PCs on my local network using their hosthame. I resolved this issue on the PC running 16.04 by adding 192.168.1.254 (ISP router) as an additional DNS server in the IPv4 settings of the wifi adapter.
I'm not able to edit the connection settings on the PC running 18.04 in the same way. I attempted to add the following netplan configuration to 01-network-manager-all.yaml (already existing file in /etc/netplan)
# Let NetworkManager manage all devices on this system network: version: 2 renderer: NetworkManager ethernets: wlp3s0: nameservers: addresses: [192.168.1.254]
Then I ran sudo netplan apply but this did not help.
Any ideas on what else I can try?
