Thank you MrSaffron, I don't think they realise that the call from BT was to upgrade them to FTTC, I was suspicious as to why BT had send them a new Hub just like that! I think they don't know they have been upgraded to FTTC. I will have to tell them as I asked them if they ever check their MyBT and they said never!!!

Those connections and disconnections are indeed local devices connecting to and from the hub. You will see the ethernet one. Also 'device' may refer to items like mobile phones in the area using BT Wifi (used to be BT FON) which use your hub on a shared basis. These are totally normal and happen all the time and have absolutely nothing to do with the broadband itself disconnecting - you will see that has been up for over a day. Do they power the hub off at night, you would obviously get a disconnect when that happened..

OK, so now we know they are on FTTC, time to check how everything is connected to the line etc ..... a bridge tap can cause loss of speed and random disconnects.

I get the feeling this could be a case of the wifi disconnecting, not the FTTC.

I could well be wrong in this instance, but a great many people don't know the difference, even now, and it's getting worse as most (written) adverts I see go on about wifi capability and how many devices can be handled simultaneously.

Like I stated in a post earlier, when they mentioned that they had received a call from BT and that they had sent a new Hub bells started to ring as to why BT would send a new Hub just like that! So unknowingly the conversation between them and BT was about selling/upgrading them to FTTC.
I have been to them two days running for about three hours at a time and whilst I have been there, there were no disconnections, all being that the laptop is now connected with Ethernet and the printer with a USB cable. Looking at the log the disconnections I posted above were also shown at the time I was there but I did not experience any internet disconnections so, those disconnections can not be the Hub disconnecting or as deseargant and RobertoS point out it could have been the WI-FI disconnecting and not the FTTC.
The couple do not use WI-FI now that I have connect the laptop with Ethernet and the printer with USB cable the only way we shall know if there are disconnections is when there children or grandchildren visit and connect their devices with WI-FI.
Just as a curiosity, a few years back while gardening in their front garden they accidentally cut the phone drop wire with a spade, the drop wire was just laying near the surface and BT had to re-route the drop wire to their next door neighbour and then to their front porch!
I don't know if there are any other diagnostics that I can carry out on the FTTC if that would help.
I still have to go back when Epson replies with advice on how to solve the printer issue which was connected with WI-FI and has gone berserk since the change of Hub and even connecting it with USB it has made no difference.

= Upselling! I should check their bills.

That is correct. I asked my neighbours today if they realised that they were now on FTTC and they said no. They were told that they would pay the same as they are now for 18 months and they would get higher speeds and a new Hub. These are an elderly couple who are not familiar with broadband packages and have been taken for a ride IMHO.

they would get higher speeds

But can they make use of them, particularly if they are only using a PC & printer on it, just doing the usual browsing, emailing, shopping, banking (maybe), printing ... ?

Their downstream is not much faster than the best ADSL2+ (they are about 1 km from the cab). Not that they are likely to be on that but what does the BTw Availability Checker say about their WBC ADSL 2+ for their phone no?

As you rightly point out they only use the internet to access their Gmail and practically nothing else other than perhaps a bit of surfing that's all.
This kind of upgrading tactic by ISPs should be regarded as misselling.
This is BTw Availability Checker for this particular phone number.
