Hello everyone,
Any android device can’t detect my HAP AC² 5GHz network. I am able to see both 2.4 & 5 GHz networks on my laptop but any mobile device can’t.
I tried multiple channels but no solution.

802.11a? n? ac?

  1. Not all Android devices have 5 GHz wifi.
  2. Sometimes the 5 GHZ band usable by a device (Android or older PC) are limited to indoor channels (36-48 , sometimes 36-64)
    3 as in the previous post: what 802.11 protocol? a,n,ac
    4 Bandwidth used: 20MhZ, 40 MHz (20 MHz Ce or eC), 80 MHz (20 MHz Ceee,eCee, eeCe, eeeC, xxxx)
    5, Spaces in SSID name ?

Load “Wifi Analyzer” in Android device to see wifi signals.

I have a similar problem. I have 5G interface default settings.
After enabling wireless logs:

wlan2: denying assoc to xx, does not support all basic rates

After deleting the content in Basic Rates A / G, VHT Basic MCS and HT Basic MCS, starts working, but only on 54Mbits.

This occurs on:
stable 6.46.4
long-term 6.45.8
testing 6.47b49

On the version dev 7.0b5, my smartphone connects without a problem on 433Mbits.
