Just for clarity's sake, while it's possible that Pyrowave streaming could cause service interruptions for other people on your LAN (and thus isn't suitable for high-traffic networks like at a company or large business), it is strictly intended to be used over your local network, not the Internet. As a result, your internet connection doesn't matter at all, so if you were worried about ripping through your data allotment on a metered connection, there's no need for alarm; all of the data sent is between devices on your network. Even the over-200 megabits-per-second of Pyrowave is peanuts compared to the tens of gigabytes per second your graphics card is sending to your display via DisplayPort or HDMI, after all.

Your internet shouldn't matter, so long as you aren't using that power line to connect all the computers in your house.

if you have coax you can look into using MoCA adapters. Quite a bit faster than powerline but you do need to add a filter to the incoming cable line (if it's connected and you can actually get to it) so your data doesn't get blasted outside your residence

We can set Bitrate manually between 100 and 500. The target is about 200mbits, so 100 would be the lowest possible value and quality. And if that is the max your entire line can give, then it's probably not a good fit for your setup. That's a bit unfortunate, but at least you can still use any regular codecs like AV1 or HEVC in example.
