RTL Device: Asus AC53 Nano, 0b05:184c
Driver: rtw88, rtw_8822bu

Platform/OS for hotspot:

  • NanoPi R6s + FriendlyWrt
    • kernel 5.10
    • kernel 6.1 (arm64)
  • Debian bookworm (amd64) + kernel 6.4

brief settings:

  • Country Code: US
  • OpenWrt Mode: AC, channel 149, bandwidth 80Mhz
  • Security:
    • WPA2 PSK CCMP
    • Open

Client devices:

  • iPhone 8 Plus
  • iPhone 14 Pro
  • MacBook Pro 2015 + macOS 13.4
  • Dell Laptop + QC61x4A +
    • Windows 11
    • Debian bookworm (amd64) + kernel 6.4

I tried on 3 Platforms, all with rtw_8822bu from rtw88, same behaviours. This makes me feel the problem may be caused by the hardware itself or driver.

The interesting thing is, only iPhone 14 Pro can successfully connect to the Hotspot, and works well.

I try with other devices, timeout, asking for password again, repeats.

Once I have a not-working device, tried to connect to the AP, the AP will soon be dead.

I also tried other security settings, same behaviors.

And an old rtl8822bu driver (https://github.com/friendlyarm/rtl8822bu) can get this device working as AP smoothly, all devices above can get connected, only problem is that driver only have the dongle running at 802.11a mode and channel bandwidth 20Mhz.

Any clue where I can collect more logs for debugging?

Looks like the same problem as i had : #112
Have you tried in 2.4GHz ?
For me i could never solve this issue for now and i'm still using the old driver due to this, it's directly related to the driver/firmware.
Good luck !

#151 could also be related

I did try a very old version of driver, https://github.com/friendlyarm/rtl8822bu, only 2.4GHz can be recognized, and hotspot works fine.

The interesting part is, with such an old dongle (6+years), only the iPhone 14 pro works.
This makes me want to find out what is different from my iPhone 14 pro and other devices during Wi-Fi connection establishing, and I'm trying to find out what I should do and how.

And yes, I read #151, error from #151 (comment) looks same as mine.
