Me, too. Today I experienced the same problem that ZebraSpud reported. My HE.NET Network Tools is v126.96.36.199, my iPhone6 iOS is v8.3, and I'm testing against iperf3 (v3.0.11, compiled locally from http://downloads.es.net/pub/iperf/iperf-3.0.11.tar.gz
) in server mode on a local Ubuntu 12.04LE host. Another local Ubuntu 12.04LE host running iperf3 (v.3.0.11) in client mode against that server works perfectly. HE, when can we look forward to a fix?
Incidentally, if I run an iperf(2) server on that same Ubuntu host, the HE.NET Network Tools iperf2 tool works correctly against it. But iperf3 is important for me because its default client settings run speed tests in both directions, essential in a WiFi setting where the transmit power of the user device may be much lower than that of the access point. Alas, the HE iperf tools give us access to just a few of iperf's many parameters.
