Return signal from phone has too low a level. Does it work reliably near the
router?
If yes, then almost certainly time to get a new phone, if not then check it
is seeing the correct form of protection. In the main if its running at
least ios 11 then it should be ok. Anything else and who knows. Most of the
Iphones since about the 8 have dual band wifi, and my 10r always uses the 5
gig band not the rather interference prone 2.5 gig one.

The last router power down seems to have cured the problem. Open Reach
have been re-cabling here so the remote connection may have been
intermittent.

The phone has accompanied the owner for a pre-op covid test and may not
be back for some time.

John has me worrying that having bullied her into switching on the wifi,
she is now carting it around a hospital!
