Will SSID with spaces work?

[jjcarstens]

I think this is more investigative based on an outstanding question from offline conversation.

The setup in the logs below is configured for network Wright 2.4, however there is a Wright SSID as well (which is the 5ghz) and the devices ability to connect to the expected network seems indeterminate and unstable (i.e. It works sometimes, or produces logs like this at other times without connecting)

It seems like there could be an issue here with spaces in the SSID, but needs to be investigated and behavior validated
