1000Base-T not supported?
Today I was struggling to get a v3 probe (TP-Link) connected to my network, the link just wouldn't come up. On a whim I tried connecting it to a tri-rate 10/100/100Base-T device, and lo and behold - it came alive! Only 100Mb, though. Is it really the case that the probes don't support 1GbE? The probe has «150Mb» printed on it, which strikes me as rather odd if it's limited upwards to 100Mb. Tore

These days it is even mentioned in the FAQ :-)
(wonders what the advantage is of 1Gbps-only ports)

Maybe the Wifi is technically 150 Mbps? There is also a 3G/4G switch on the probe. Chinese marketing? Philip

*blush* - sorry for the noise!

FWIW, all the SFPs I stock are single-rate, and the switch I tried to connect the probe to can only accept single-rate 1/10G SFPs anyway. Tore

100M full-duplex, thus 200M throughput! :-) Maybe the Wifi is technically 150 Mbps? There is also a 3G/4G switch on

Indeed, 802.11n with a 40M wide channel maxes out at 150M. I'll guarantee you'll get higher throughput via wired and lower latency and jitter, plus far fewer hassles. Plug it in and walk away. I'm hoping/expecting that RIPE never supports wireless in these probes. Chris.

There are some specific cases where measuring wifi makes sense. But that will be in addition to wired ethernet and not instead of. Philip
