Thanks onslow. I tried this last night but problems seemed to continue.
Looking at the forums it seems that others are experiencing this problem and therefore I am thinking it is more likely a congestion/routing issue at BT.
Is it possible to change the DNS forwarders on the HH4? I would prefer to update this rather than amend the DNS settings on my client devices.
Did you try changing the DNS on your computer? Change it to 188.8.131.52 and see if that makes things better. It did for me. This to me implies it's either the HH or a BT network problem. The latter seems more likely as some sites worked and some didn't and others were slow to load until I changed it. If I set it back, then the same issues return.
I guess this may differ from person to person.
I don't think you can alter the DNS server on a HH4.
Could you try altering just one device just to prove that this is a solution to your problem?
I use mainly Chromebooks for surfing the web, very simple to change the DNS Server:
Can you borrow a Chromebook, alter the DNS Server, then see if it cures your problem?
Interesting, I have been having this problem for a few days. It's definitely not a DNS problem as I have tried both BT and Google DNS. Just disconnected my TP Link router to play with a HH5 and the problem has disappeared (back on TP Link). Don't know whether the problem is IP address related (presume I have a different one after the disconnect, didn't check) or the reset was sufficient.
Same issue here in Oxfordshire with infinity 1 for several days... No problems on a smartphone with 3G.
This is more than annoying as I use the connection to work remotely and my secured VPN website loads once per 20 or 30 tries..
Also changing DNS does not help, unfortunately 😕
I'm also in Oxfordshire with these problems.
I've also tried the Google DNS and it makes no differene for me.
