WiFi messed up by Openreach, I reckon

Cut the new cable they installed.
Remember that you are dealing with Talktalk.
Coverage is only guaranteed for in the home is their fall back.

does sound like Co-Channel interference. Has a neighbour added to their network? Use the scanner as suggested by pops above.
One's a rechargeable battery camera, the other solar powered, and they work off the Wifi. So I can't connect any cables to them to enhance the signal. Thanks re the TAPO recommendation, by the way.
Believe me, I did consider it, briefly. But I'd be leaving myself open to at best a ticking off for interfering with communications equipment and at worst, a bill for putting it back together.
I had a word with my neighbour's daughter yesterday and she confirmed that her elderly Mum is having an upgrade to her Wifi next month. She wasn't expecting them to put any hardware in place till November and was slightly miffed that they had. Her Mum is with EE, so the daughter is going to ring them on Monday and tell them that a neighbour is having problems because of what the engineer has done, so maybe that'll prompt Openreach to come back and fix it.
It won't be anything to do with the Openreach fibre 'cabling' work... That uses light not wireless radio signals.
It'll be localised WiFi radio interference. Most likely other users of the no licence required radio bands used for WiFi internet (and home automation and bluetooth and...).
Changing channels your system uses or reinforcing the signals in/around your home with meshed wifi repeaters is the only solution.

Thanks for the further food for thought.
Unlike others I can't provide an informed analysis of the possible reasons for the change in Wifi coverage nor expound upon any solutions, but for me the timing is conclusive. After two and a half years of excellent coverage, things changed after the visit from the Openreach engineer. I'm hoping my neighbour's daughter manages to persuade EE to escalate to Openreach because I think its unlikely that I'll persuade TalkTalk to do the same.
Wonder if your physical connection in that box was never the best and the visiting engineer knocked it
That shouldn't have any impact on the wifi coverage. The broadband speed and Wifi coverage are (largely) independent of each other.
The OP has a wifi MODEM router. The MODEM part acts as a gateway to the internet. The router part distributes that access to connected devices (via ethernet or Wifi).
That devices close to the router seem to function as normal, I still think it is down to clashing WiFi channels.
Let's say that a wifi router in a field has a 50m radius of coverage, if someone adds a different router nearby, the coverage of the first router will drop. If the second router is on the same channel, the coverage of the first will drop massively. The two signals are effectively competing for the same airwaves.
My advice to the OP is still to use a wifi scanner.
You can verify if it is the incoming cable speed, or the WiFi, by connecting a cable to the back of the router, and running a speed check
Desktop pcs, and some laptops, are likely to have a LAN socket. Tablets probably won't.
But you can get a connector cable with an RJ45 (?) Plug on one end, and a USB C on the other.

I had issues once and the WiFi scanner app was really useful. Problem I had Was that I could change the channel but the talktalk router would change it back after a short while.
It could also be that the OPs router has a fault with the 2.4ghz and only the 5ghz is working which is rubbish at going through walls.
Coincidence. Pure coincidence.
Unless the work was to provide broadband to the neighbour, and the neighbour then installed WiFi that is causing the trouble.
