Poor wireless performance

[jgauthier]

Hello,

  I am using a NanoPi Duo2 with Armbian 22.11 and Kernel 5,15,80.

This device uses an AP6216 wireless interface, which I have noticed are pretty common on sunxi based boards.  

I ran some bandwidth tests and had pretty poor results:

[ ID] Interval       Transfer     Bandwidth
[  3] 0.0000-1.0000 sec   129 KBytes  1.05 Mbits/sec
[  3] 1.0000-2.0000 sec   129 KBytes  1.05 Mbits/sec
[  3] 2.0000-3.0000 sec   127 KBytes  1.04 Mbits/sec
[  3] 3.0000-4.0000 sec   129 KBytes  1.05 Mbits/sec
[  3] 4.0000-5.0000 sec   129 KBytes  1.05 Mbits/sec
[  3] 5.0000-6.0000 sec   127 KBytes  1.04 Mbits/sec
[  3] 6.0000-7.0000 sec   129 KBytes  1.05 Mbits/sec
[  3] 7.0000-8.0000 sec   127 KBytes  1.04 Mbits/sec
[  3] 8.0000-9.0000 sec   129 KBytes  1.05 Mbits/sec
[  3] 9.0000-10.0000 sec   129 KBytes  1.05 Mbits/sec

 

Not sure if the issue was the driver, hardware, or otherwise I connected a USB wifi dongle and disabled the AP6216.

I've tested with the same results again:

[ ID] Interval       Transfer     Bandwidth
[  3] 0.0000-1.0000 sec   129 KBytes  1.05 Mbits/sec
[  3] 1.0000-2.0000 sec   129 KBytes  1.05 Mbits/sec
[  3] 2.0000-3.0000 sec   127 KBytes  1.04 Mbits/sec
[  3] 3.0000-4.0000 sec   129 KBytes  1.05 Mbits/sec
[  3] 4.0000-5.0000 sec   129 KBytes  1.05 Mbits/sec
[  3] 5.0000-6.0000 sec   127 KBytes  1.04 Mbits/sec
[  3] 6.0000-7.0000 sec   129 KBytes  1.05 Mbits/sec
[  3] 7.0000-8.0000 sec   127 KBytes  1.04 Mbits/sec
[  3] 8.0000-9.0000 sec   129 KBytes  1.05 Mbits/sec
[  3] 9.0000-10.0000 sec   129 KBytes  1.05 Mbits/sec
[  3] 0.0000-10.0191 sec  1.25 MBytes  1.05 Mbits/sec

 

It's my suspicion that the issue is now elsewhere - but where?  I have no idea.

 

Thanks for any ideas.

Good news!  I'm dumb!  iperf defaults to a 1M transfer rate over UDP.  Easily changed with -b option.
