Sorry, that is far too involved for me to help you with. Perhaps another forum member can help?
Hi . It was a while ago and I am not sure this relates to your issue.. I had an alarmingly bad experience with the BT HomeHub5. One of which was DDNS and accessing NoIP.com ; the problem was that I was (validly) using #, (hash) and other non -alphanumeric characters in the password to log-in to NoIP.com. It seemed that the HomeHub5 was (invalidly) unable to process this password- I believe that it was using # and other characters in its internal software functioning and this was tripping the DDNS login transaction to NoIP.com.
From memory I think hash and space, maybe underscore too, were forbidden within any DDNS password.
When I changed to a simpler less secure alphanumeric password it all worked.
After I got the HH5 working it proved unreliable on the DHCP front, failing to serve IP addresses in my system on many occasions, requiring reboot. Ditching HH5 and switching to a Draytek 2760 was the best thing I did and the home network functioning has been reliable since.
Hope that helps. Good luck.
I looked at getting a different router. Noob question here, can I just get a new router and plug it in? Does it require serious setup to work with BT broadband?
Very easy with most routers.
Here are a couple of suggestions.
TP-Link AC1200 Wireless Dual Band VDSL/ADSL about £67
If you only want single band wireless, then this one.
The TP-Link TD-W9970 for about £40 or less.
They both work will all BT services, including BT YouView.
If you are served by BT line / VDSL, it appears the service authentication to the broadband modem is purely by the username string like
Check what your HomeHub has for its entry. and use this in the approriate field.
