I was failing to connect a Wi-fi repeater to my laptop via Ethernet. It is a very simple device. It about the size if a plug, and says connect to 192.168.11.1. I did, and it didn’t connect.
Once I spotted the problem, it was obvious.
On Linux, I had to configure the wired connection so support this address. Under IPv4, I added
Routes
192.168.11.1 | 255.255.255.0 | 10.1.0.2
and it all worked.
Simple when you know how!
