I have a TP Link Archer VR1600V as my modem/router. I've just set up a hardwired connection from one if its LAN ports to another router (downstream). Everything works OK. But I'd like to check that the hardwired connection is working properly - ie at 1Gbps.
How can I find out whether a LAN port on the VR1600V is at 10, 100 or 1000?
PS: Please don't suggest that I check on the other device. After a frustrating week I've concluded that's impossible.
Thanks for your help.
