Uk Vodafone Issue

Hi all
You likely heard of the outage from Vodafone here in the UK.

They reckon it wasn't a hack (yeah right) and everything is hunky dory now.

Well, it isn't, as can be seen by the reports on Down Detector, and getting one of their 'techies' to sort it out is a nightmare.

Since the outage I have had what I think are drop outs.
Speed to the hub is fine, it's as though it can't get out 'smoothly'.

Done all the usual, resetting everything.

When I log into my hub via 192.168.1.1 I keep getting a sign in box popping up while I'm going through the settings (which I think makes several appearances due to the page refreshing, see next paragraph) asking me for my user name and password. (Pic added) Never had that before.



I also noticed the browser page when I am logged into the hub seems to refresh every now and then.
That seems to coincide with similar timings when movies on the TV are buffering, which happens over LAN or WiFi.

I logged into my neighbours WiFi and there was no issue at all, so it's not my equipment.

I have issues both over WiFi and LAN.

My desktop computer is LAN, which is taking ages to load pages, even the browser page to the hub, which should be instantaneous.
Strange thing is, if I switch ports then all seems ok, for a while.

So, with all the above, 192.168.1.1 page refreshing, buffering on the TV over WiFi and LAN etc, are drop outs likely the problem and does anyone have a clue?
Cheers
