Yes, but we are all geeks here. Has J.Random User internalized that
wifi can really suck for TV usage?

I have also used powerline adaptors in the apt, while bloated and slow
(200/4mbit is what I get out of mine on the rrul test) - they only
exhibit 90ms delay under load. I wish there was a way to get into
these to get fq_codel in there, they are conceptually a lot simpler
than wifi... but I am only aware of one open source driver for one
chipset, and otherwise these little boxes are a mystery.
