My wifi SSID has a space in it, when I input this into the web interface, it results in /etc/network/interfaces containing:
wpa-ssid Firstwork Secondword
This doesn’t seem to work, however if I actually enter “Firstword Secondword” into the web interface (with the quotes), the interfaces file contains:
wpa-ssid "Firstwork Secondword"
which does work.
Likewise, my wifi password contains special characters, I have always seen these escaped inside quotes on Debian, for example:
but Volumio doesn’t do this, it just puts in something like:
Again manually adding the quotes via the web interface fixes this up, but that’s a pretty obscure workaround.
Ideally, the Volumio web interface should add the quotes so that /etc/network/interfaces always ends up with quotes around the SSID and PSK.
