@dougie - it' a good question (because many people say NOOBS when they mean Raspbian installed via NOOBS). But I think in this case, the "swishing back and forth" of the progress bar is indicative of NOOBS rather than Raspbian.
IIRC NOOBS, uses simpler regulatory information, and I don't remember a country code being specified in wpa_supplicant.conf, so I suspect the problem is connecting to an SSID channel that is not valid for the default settings (is it channel 12/13 on 2.4GHz, for example?).
Maybe changing the channel number of the wifi access point would help (e.g. to channel 6)? I'm not sure about 5GHz channel number restrictions.
There may also be problems connecting to Enterprise setups or hidden SSIDs.
