Hi,

just wanted to share my recommended settings, which are maybe not the most performant ones, but to me personally the most reliable ones having RTL8812AU / ALFA AWUS036ACH in 2.4GHz b/g/n (only) AP mode. Most important thing to me was ensuring continuos (gapless/ stutter free) playback on the Squeezeamp through cspot (spotify connect endpoint) while other devices might drain the line through VOD or 1080p streaming etc. so I hope it might be still a valueable feedback.

Hardware:

• Raspberry Pi 5 Model B Rev 1.0
• nvme-KINGSTON_SNV2S2000G
• ALFA AWUS036ACH

OS:

• 6.1.0-rpi8-rpi-2712 #1 SMP PREEMPT Debian 1:6.1.73-1+rpt1 (2024-01-25) aarch64 GNU/Linux

Test devices / setup:

• Squeezeamp (ESP32)
• Iphone 13mini
• linux desktop

Scenarios (in order as they appear) :

• starting a playlist (320 ogg) on squeezeamp
• starting a VOD (1080p) through twitch through linux desktop
• starting a livestream (1080p) through twitch on Iphone13

or

• starting a playlist (320 ogg) on squeezeamp
• starting a livestream (1080p) through twitch on Iphone13
• scp-ing 7 albums of flac files from linux desktop to rpi

All of those doesn't interrupted or slowed down the streaming on any device which is more then great :)

Can I get you to test the following:

ht_capab=[SHORT-GI-20][RX-STBC1][MAX-AMSDU-7935][DSSS_CCK-40]

I will explain when you report the results. Thanks for bringing this up as I have found a couple of bugs already.
