@Xemik, thanks for returning your router. I've applied a £10 credit to your account that should be deducted from your next bill.
Okay, thanks. I would have been happy with just the postage, but I'll not complain. 
I have the router connected as-is here in the office with a number of wireless clients associated with it, and will keep an eye on things over the coming days...
Hope it provides some answers.
The new router has been up for 4.5 days so far. It's currently 56/9, but the max has been fluctuating between 57/9 and 53/9; it seems the line hasn't stabilised yet. Of course, I don't know if my line has been moved in the exchange yet, so I'm keeping an eye on it.

It seems like there are a few of us (@Marksfish, @Xemik, @bobmanekshaw) getting similar problems with WiFi dropping out whilst the wired connection continues to function until the modem decides to reboot itself.
For well over a year we have been using the following devices on our WiFi n/w:
[snip devices]
The broadband setup has been working fine, until the hub was remotely rebooted with FW 4.7.5.1.83.8.259.1.1 at 01:00:51 on 30/09/18 (downloaded by https://dbtpnhdm.bt.mo on 27/09/18 03:41:27). Thereafter the WiFi connection has been erratic.
When WiFi disconnects, both SSIDs disappear. They only reappear when either the hub is restarted manually by ourselves, or after a couple of hours or so it restarts itself (I assume). The WiFi will either stay on for a short period and disappear again or will stay on for a few hours before it goes.
My experience is pretty much identical to yours and I know the exact date the wifi issues started - back in September when the 259.1.1 firmware was installed. A rollback cured the problem.
Tried a new Hub 1, but that didn't fix the problem. Initially, it didn't reset as often, then it got progressively worse. Bizarrely, the wifi would drop over night and the router wouldn't reboot until I connected my wired desktop. I'm not sure, but it seem that the router needed the wired connection to kick it back into,life.
On the plus side, I did actually have a minor fault on the line between cabinet & pole, which BT have fixed. Engineer also fitting a new faceplate while he was here. Probably would have gone unnoticed but for the router issues.

As the consensus is that this is a firmware issue, I'm wondering if I need to ditch the PN hub and replace it with something that will work. Alternatively, reinstall the old hub and persuade PN to reinstate the old firmware, as 4.7.5.1.83.8.259.1.1 and 4.7.5.1.83.8.259 are not fit for purpose in my circumstances.
It's not for me to say, but after a month of this I got fed up and decided to buy a wifi router to attach to the Hub 1. After a bit of research I found that the price differential for a modem router was so small I bought one of those instead. Worse case scenario, it could still be used as a wifi router if it didn't connect to PN.
All my important stuff is wired, so I didn't need a high powered wifi router. ITE I bought an Archer VR900, which got outstanding reviews for it's price/performance. I'm happy with it and the b/b has been up for over 6 days now.
I sent the replacement Hub 1 back to @bobpullen who's currently testing it to try and find a fix for this oddity. So if you'd rather not spend the money, it might be worth waiting a little while.
@BaltiSalty, please leave the current device connected. I'd like to grab some logs from it. Once I have, happy to downgrade your firmware. If I do though, there's a good change your device will reboot once a day during the early hours. You may also be targeted with an update over the coming weeks/months. I can't stop that unfortunately.
FYI, both the .259 and .259.1.1 firmwares contain the same wi-fi drivers etc. (assuming of course that this is where the problem lies).
@Xemik, the device you returned has been up for over 2 days now with a load of smartphones connected to it and it's yet to reboot/drop the wi-fi connection

How old are these devices? I assume you haven't changed the wifi settings, so they should be set to Mixed. I was wondering if the age of the connected devices might be causing an issue. One of my devices is an original Kindle Fire HD's and occasionally we connect an old Samsung Note 4.
@BaltiSalty, thanks, I've now downgraded the device. When you return over the weekend, let me know if it's helped.
@grahamt, thanks for the offer. Will let you know if there's anything you can do to help
