If Volumio's wireless network scan does not return your network and your network wireless network is on channels 11,12 or 13 it is necessary to enable those extra channels (if allowed by your country legislation).
To do so:
1) Enable SSH
2) Connect to Volumio via SSH
3) Username: volumio, Password: Volumio
4) Type: sudo su
5) Enter Password: volumio
6) Type: echo "REGDOMAIN=IT" > /etc/default/crda Where IT is your country code. See this list to get your country code: https://www.iban.com/country-codes (You need the Alpha-2 Code)
7) Type sync && reboot Optionally: if you want to verify that your country has been set properly, do all steps before step 6 and type: sudo iw reg get Password: volumio You should see: global country IT: DFS-ETSI (2402 - 2482 @ 40), (N/A, 20), (N/A) (5170 - 5250 @ 80), (N/A, 20), (N/A), AUTO-BW (5250 - 5330 @ 80), (N/A, 20), (0 ms), DFS, AUTO-BW (5490 - 5710 @ 160), (N/A, 27), (0 ms), DFS (57000 - 66000 @ 2160), (N/A, 40), (N/A)
