This is an interesting tool I just learned about, iPerf. It has a server and client mode. You can install it on a PC, but you need admin access to the PC.
It has a client and server mode. As client I was told to run the following test:
c:\apps\iperf> iperf3 -c 10.12.13.10 -b 50M -l 1024k -w 512k -t 25
