I am trying to diagnose Zoom drops / connection unstable messages when connected from my laptop using 5Ghz on my RT3200 (160Mhz on channel 36, country code: US). What would be a good 'iperf3' client command to execute on my laptop to stress test Wi-Fi for stability to hopefully capture the problem?
start by running an continuous ping from the client to the router, see if there are any spikes in the traffic.
For UDP, run for 60 sec with 5 sec intervals, aim for 1Gbps, and open 4 streams.
iperf3 -c 10.0.2.5 -f m -t 60 -i 5 -V -u -b 1G -P 4
For TCP, open 4 streams and run for 60 sec with 5 sec intervals
iperf3 -c 10.0.2.5 -f m -t 60 -i 5 -V -P 4
How about flent? e.g.
flent rrul -p all_scaled -l 60 -H flent-fremont.bufferbloat.net -o graph.png
