I have no idea how much background knowledge you have about networking, but let's start with the basics, if you plug in the ethernet
cable into the avalon, do you see a link status light going up in your laptop? Do you even have a working physical connection?
When I plug in the ethernet cable into the Avalon then into my laptop a new connection appears in Networks and Sharing Center and that is the one I edit the IP for correct to 192.168.0.101?
I never used Windows (I guess that is what you are using?) but yes, it seems like you get a link-up.
If you set the IP to 192.168.0.101, what did you set the netmask and gateway too? Try 255.255.255.0 and 192.168.0.100
If you have wifi, make sure it's not having the same 192.168.0.1/24 subnet
After you save your settings, can you disable-enable the networking so it actually reloads the values?
