If you have access to the web admin page there is a 'System Information' link under 'Map Utilities' and it lists all sorts of info. To answer your question it displays;

OS Info
PRETTY_NAME="Raspbian GNU/Linux 10 (buster)"
NAME="Raspbian GNU/Linux"
VERSION_ID="10"
VERSION="10 (buster)"
VERSION_CODENAME=buster
ID=raspbian
ID_LIKE=debian
HOME_URL="http://www.raspbian.org/"
SUPPORT_URL="http://www.raspbian.org/RaspbianForums"
BUG_REPORT_URL="http://www.raspbian.org/RaspbianBugs"

I hope this provides the info you are looking for. I'm not familiar with the difference between WPA-Enterprise and WPA-Personal so I'm not sure I can help much with that. If you do figure it out, please let us know what you did so that its documented. - Mark

An update, but not a solution yet.

Rasbian uses NetworkManager, so you can't just configure wpa_supplicant.conf.  I found this guide on how to do it:  https://github.com/wylermr/NetworkManager-WPA2-Enterprise-Setup, so I've created a Network Manager file to use with my enterprise SSID.  I created a file with my network config like this:

[connection]
id=(my SSID name)
uuid=(generated with uuidgen)
type=wifi
permissions=

[wifi]
mac-address-blacklist=
mode=infrastructure
powersave=2
ssid=(my ssid)
security=802-11-wireless-security

[wifi-security]
key-mgmt=wpa-eap

[802-1x]
eap=peap
identity=(my username)
phase2-auth=mschapv2
password=(my password)

[ipv4]
dns-search=
method=auto

[ipv6]
addr-gen-mode=stable-privacy
dns-search=
method=auto

I can see the new defined connection (nmcli connection show), but if I try to change the connection, it seems to disconnect from the PSK network but it won't connect to the new definition.

Next step: I think I might need to change to the NL80211 driver instead of the driver that's being used by default, but no guarantee that will work.

I'm sorry, I wish I could be of help with this. But you have ventured far from my knowledge base. I appreciate you continuing updating your progress here though. It will undoubtedly help others. - Mark
