I don't know what wpsk is. Here I use WPA2-PSK(AES) which seems
to be secure enough. Our household couldn't function without
wifi which is why we bought a wifi router.

I have no idea what that radio would be running. When I typed the
above into google, the one project I looked at was only running
WPA-PSK(TKIP). That's hackable, isn't it?

Until recently, our house was serviced by two meters: the new one
which comes underground to the new part, the old one which came
overhead from the easement (where you'd normally expect a back alley)
from a different street. The router sat in the old part (where the
Cox cable comes in from the same pole as the old overhead power),
and we used it from the new part, with very low signal strengths.

Now we've connected the giant cable between the two breaker boxes
and removed the old meter, we can use Powerline 1200s to link the
modem (old part) to router (new part, where we are). Once we've
remodelled the old part and start using it more, we could use
more Powerlines¹ for static things like TV, but will probably
need wifi there as well.

One advantage of Powerlines is that they aren't bothered by
microwaves which knock out nearby 2GHz devices. 5GHz isn't
bothered by the microwaves, but this part of the house seems
rather solidly built and I'm disappointed by the 5GHz performance
here compared with our previous house. By the time we've wrecked
the inside of the old part, the more open layout (the "reception
rooms" in UK parlance) might suit 5GHz a bit better.

¹We'll have to change the whole topology of course, because at the
moment the pair of Powerlines are carrying the (unshareable) WAN
side of the router rather than the LAN side.

Cheers,
David.
