Thank you for incorrectly projecting your usage patterns onto me.

Again, thank you for making incorrect assumptions about the type of
video being tossed around.  My streams are more like 10-20Mbps each.
Just looking at one recording I see 14.5Mbps.

BZZT.  You're off by a factor of about 3.

Even at 20Mbps, it's really only using 2.2% of the available b/w.  At
14.4Mbps it's down to 1.6%.

No, realistically it can only deliver 1.  That is not sufficient.

Says you.

Listen, this back and forth with you is fruitless.  You're not going to
convince me to go without wires, and I'm clearly not going to convince
you that there are cases where wired networks are better.  So let's just
agree to disagree and then I can get input from other people with
insight into the best wired technologies to install.
