5 of my 6 cameras went offline sometime on Monday evening (camera and firmware details below) and will not come back online. Have tried simple power off and on, reset gets through connecting to wifi then sticks on pairing in the app and the LED is on solid red.

We are in a large, old house and use a Three 5g mobile broadband box connected to a TL-PA8010P and 8 TL-WPA8631P units around the house and 2 outbuildings. The network has been working fine for 18 months though, presumably because of the old electric wiring in the house, I need to switch off and on the powerline units every month or so to keep everything working well. After a few glitches streaming music over the network on Monday I switched the PA8010P unit off and on and 5 of the cameras have not worked since then. One camera in an outbuilding is still working fine.

We also have 6 P100 smart plugs in the house and these are all working fine. I'm stuck with this now as the cameras are responding to a reset but only as far as connecting to wifi and then the LED goes solid red. Any advice please?
