Nothing to explain in wiki, SSID Regexp: in Access List Rules
Mikrotik always is developing good things for us, but no explain to their Users how to use!!!

If the SSID that the user connects to matches the Regex in that field, then that Access Rule will apply to that user. So if you have 3 SSIDs “Office1” “OfficeB” and “Public” you could make an SSID Rexexp to match the two Office SSIDs and apply an access rule to all users on them.
Thamk you, but is it not much simply per Interface?
Example: User Mac FF::FF:FF:11:11:11 Allow to connect on cap1 with ssid Office1
What is when I’ve a Network for smartphones, 150 AP’s configured as Cap, all Ap’s the same SSID???
Simple leave this as blanc???
If you only have one SSID, then using the SSID Regexp field is probably meaningless for you. It’s optional.
Thank you for Help!
Is it possible to setup interworking-profiles on CAP’sMAN administrated Ap’s, Cap, for future Hotspot 2.0 propose???
