For me yes, i've got pretty good results, with quick test iwinfo show :
phy0-ap0  ESSID: "Turris"
           Access Point: C0:3F:0E:xx:xx:xx
           Mode: Master  Channel: 1 (2.412 GHz)  HT Mode: HT20
           Center Channel 1: 1 2: unknown
           Tx-Power: 19 dBm  Link Quality: 46/70
           Signal: -64 dBm  Noise: unknown
           Bit Rate: 108.3 MBit/s
           Encryption: mixed WPA2/WPA3 PSK/SAE (CCMP)
           Type: nl80211  HW Mode(s): 802.11b/g/n
           Hardware: unknown [Generic MAC80211]
           TX power offset: unknown
           Frequency offset: unknown
           Supports VAPs: no  PHY name: phy0

With a Galaxy S20 FE 5G and SatStat application, I get -55dBm signal at 6 meters~ radius with wall between.


The AP have been up for 15days, en exept some messages on dmesg, work pretty good:

Ps: I've played with my mail server configuration yesterday, sorry for the multipost...
