The results are helpful.

The reason for checking the Network Diagnostic menu is sometime the antenna in Radio gets broken. The 100% and some of the other details seem to indicate that wifi is OK.
The appearance of the address as 34.243.12.154 (amazon address) and 34.244.221.118 (mysqeezebox.com) mysqueezebox.com seems to indicate that DNS is working.
Do you use DHCP ?

The answers to the test indicate that your radio is connected to mysqueezebox.com and not a local LMS sever.

I don't know your setup -
Do you have a local LMS server on your home network (server version is shown in WebUI Setting/Info tab)
If you have a local LMS server - go to Radio top level menu (home button) and select My Music, connect to local LMS and then run Server Info menu again.
