The country=United States override existed to reach UNII-3 (5745 MHz),
which is not permitted in the EU. It cost more than it gained: clients in
the BG regulatory domain were power-restricted on those channels.
Setting country=Bulgaria raised the test client from 241 to 295 Mbps
immediately and ~451 Mbps once rate adaptation settled, with client signal
improving from -72 to -67 dBm. Total gain this session: 38 -> 451 Mbps.
Also:
- cfg-xtrm security.encryption tkip -> ccmp (provisioning rule 0 would
have handed TKIP to any new 5GHz CAP interface, forcing legacy rates)
- cap-wifi1 moved to 5220 MHz (ch 44, non-DFS, legal in BG); still disabled
- Corrected: HAP wifi2 is disabled with encryption="", not tkip
- Noted that country does NOT hard-block an illegal frequency
