Hello, As I can reproduce this on my amd64 laptop too, I'll will test from here instead of rpi4 that is using RTL8821AU mode 11ng stable.
On my laptop, RTL8811AU shows: A: wlanstat before connections B: run iperf3 -R (-R is the fastest way to reproduce) C: wlanstats after iperf3 A: % wlanstats 1 rx discard mgt frames 2 rx ctrl frames 1996 rx beacon frames 18048 rx element unknown 13 rx frame chan mismatch 1 active scans started 28 ccmp crypto done in s/w 2017 rx management frames 2 rx action frames 304 A-MSDU frames received 207 A-MPDU frames held in reorder q 2 A-MPDU BAR rx successful 207 A-MPDU frames rx out-of-order 2 A-MPDU frames discarded for out of range seqno 204 A-MPDU frames sent up due to old age 2109 total data frames received 2081 unicast data frames received 28 multicast data frames received 1983 total data frames transmit 1983 unicast data frames sent 180.0M current transmit rate 20.5 current rssi -95 current noise floor (dBm) -74.5 current signal (dBm) B: % iperf3 -c hp -R Connecting to host hp, port 5201 Reverse mode, remote host hp is sending [ 5] local 192.168.1.82 port 46048 connected to 192.168.1.100 port 5201 [ ID] Interval Transfer Bitrate [ 5] 0.00-1.01 sec 0.00 Bytes 0.00 bits/sec [ 5] 1.01-2.01 sec 0.00 Bytes 0.00 bits/sec [ 5] 2.01-3.00 sec 0.00 Bytes 0.00 bits/sec [ 5] 3.00-4.00 sec 384 KBytes 3.15 Mbits/sec [ 5] 4.00-5.00 sec 256 KBytes 2.10 Mbits/sec [ 5] 5.00-6.00 sec 0.00 Bytes 0.00 bits/sec [ 5] 6.00-7.00 sec 0.00 Bytes 0.00 bits/sec [ 5] 7.00-8.00 sec 0.00 Bytes 0.00 bits/sec [ 5] 8.00-9.00 sec 0.00 Bytes 0.00 bits/sec [ 5] 9.00-10.00 sec 0.00 Bytes 0.00 bits/sec - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-10.00 sec 768 KBytes 629 Kbits/sec 42 sender [ 5] 0.00-10.00 sec 640 KBytes 524 Kbits/sec receiver rtwn0: rtwn_rx_copy_to_mbuf: could not allocate RX mbuf rtwn0: rtwn_rx_copy_to_mbuf: could not allocate RX mbuf rtwn0: rtwn_rx_copy_to_mbuf: could not allocate RX mbuf rtwn0: rtwn_rx_copy_to_mbuf: could not allocate RX mbuf rtwn0: rtwn_rx_copy_to_mbuf: could not allocate RX mbuf rtwn0: rtwn_rx_copy_to_mbuf: could not allocate RX mbuf rtwn0: rtwn_rx_copy_to_mbuf: could not allocate RX mbuf rtwn0: rtwn_rx_copy_to_mbuf: could not allocate RX mbuf rtwn0: rtwn_rx_copy_to_mbuf: could not allocate RX mbuf rtwn0: rtwn_rx_copy_to_mbuf: could not allocate RX mbuf rtwn0: rtwn_rx_copy_to_mbuf: could not allocate RX mbuf C: % wlanstats 1 rx discard mgt frames 2 rx ctrl frames 3535 rx beacon frames 31899 rx element unknown 13 rx frame chan mismatch 1 active scans started 47 ccmp crypto done in s/w 3557 rx management frames 3 rx action frames 761 A-MSDU frames received 266 A-MPDU frames held in reorder q 2 A-MPDU BAR rx successful 266 A-MPDU frames rx out-of-order 2 A-MPDU frames discarded for out of range seqno 262 A-MPDU frames sent up due to old age 3836 total data frames received 3789 unicast data frames received 47 multicast data frames received 3339 total data frames transmit 3339 unicast data frames sent 180.0M current transmit rate 22.0 current rssi -95 current noise floor (dBm) -73.0 current signal (dBm) Adrian Chadd <adrian.ch...@gmail.com> escreveu (sexta, 25/04/2025 à(s) 22:12): > > Hm, knowing if its NIC or VHT/11ac specific would be good. > > What's "wlanstats -i wlan0" show before and after you've done a bunch of test > traffic?
