The mains network shouldn't be affecting the WiFi. The WiFi is on

Couldn't be arsed to google when I wrote that and that particular
memory cell seems have suffered a failure.

"Which frequency range is HomePlug AV using? Does HomePlug have any
plans to use higher frequencies (e.g. above 30 MHz) and if not, why?

HomePlug AV uses frequencies in the range of two to 28 MHz. The IEEE
1901 standard extends this range optionally to 50 Mhz. HomePlug AV2
will utilize additional frequencies above 30 MHz to increase
throughput."

That would be a neat trick, given the published data rates.

If you are thinking that to carry 100MBps of data you need a 100MHz
carrier think again. Each transition can carry more than one bit of
information and these are spread spectrum transmissions as well.
Something approaching 1000 individual carriers in the case of
Homeplug.

High bandwidth "video ready" powerline interferes in the WLAN 2.4GHz
range, as has recently been published by OFCOM (I'm trying to find a
link to the FoI stuff that doesn't go via The Register, who I am
boycotting).

Is this wide area powerline stuff or the domestic house and not much
further powerline comms?
