I just now have seen this message. Just pulled my opal back out to try what you said though.
Weird… I got netperf installed. the speedtest-netperf gives
root@GL-SFT1200:/etc/speedtest# ./speedtest-netperf.sh

I downloaded betterspeedtest.sh and ran it, even adding a high -t (seconds) didn’t do nothing it seems… When I tried, it immediately gives a finished test result, even though I added more time and more connections…
