Thanks guys, just wanted to cap the speed to the kids to 100 mb each so no one of them hurts the others or me too much if they have a big download going on
If their PCs are locked down then you could change the NICs' properties to be 100 Mb instead of 1 Gb.
Nope just PCs unfortunately.That wouldn't work for consoles though ?
I would be very surprised if the powerline themselves are syncing even close to 100mb. Most times I see ~50mb odd on average.
Which powerlines are they? Depending on the brand they sometimes come with an app that can tell you the speed between each powerline node. If not, just do a test large file transfer between PCs.
EDIT: For TP-Link, this should be it: https://www.tp-link.com/uk/support/faq/1086/
