Wifi boosters

[Vimana.]

That's what I was looking for, I think. Have you had any experience with them?

Aye, typing this upstairs connected through a Powerline adapter now.
Just a couple of Mbps less than directly into the router downstairs.

Wifi is decent here upstairs too, but has nowhere near as good a throughput as the powerline adapter.

The Wife's parents asked me to set up a wifi booster for them last year ('signal' was poor in their garden) , and I tested it here first too - out of curiosity.
Good signal, but vastly reduced bandwidth.

Reason being - the wifi booster has to engage in a round-trip dialogue with the router, and also a round trip dialogue with the conected device - at the same time. Thus, big loss in throughput is inevitable. Unless technology has rapidly changed since I last looked ;)
