My broadband package is Fibre with Halo 3, not sure what you mean by BT Digital Voice?
Do you use your phone service?
Halo 3 extras would not work with a different router.
When you get the disconnections, do the lights on the home hub change colour, indicating a line fault?
I do use BT phone service.
When the hub disconnects the lights go orange and then flash and return to blue
Then you have a line fault, so its unlikely using a different router will help. How many times have you reported the problem to BT?
If you really want to prove it, then buy a cheap basic router and try that and see if that disconnects.
Provided you have a VDSL (copper connection) under 80mbs, and are happy to have a 2.4GHz wireless signal, then one of these will work https://www.tp-link.com/uk/service-provider/dsl-router/td-w9970/
Cost about £33 from Amazon and £40 from Argos. You can normally return them if you still get the disconnections.
If you must have dual band wireless, then https://www.tp-link.com/uk/service-provider/dsl-router/archer-vr400/
That costs nearly £80.
I certainly do have a line fault as there is a crackle on the line, I have had many BT and Openreach engineers visit my house over the past few months but they can never find a fault. I am still in talks with BT regarding this issue and over the past 10 days I have had two engineer appointments booked both times no engineer turned up. I have sent a few messages to my BT contact using BT community but they haven't responded. It's absolutely ridiculous, I know there is a fault on the line as when I use my landline I ask the person I am speaking to if they can hear a crackle on the line and they always say yes. I am exasperated, I just don't know what to do!
Then you would be wasting your time and money trying a different router, as its a line fault.
Did you contact @RobbieMac as requested here https://community.bt.com/t5/Home-setup-Wi-Fi-network/Smarthub-2-disconnecting/m-p/2261704#M198841
There was no update to this thread as to the result.
Changing router will be completely pointless.
How are you reporting this fault, as broadband or phone? I would suggest that reporting a phone fault is more likely to result in a fix as it's too easy to dismiss a broadband fault.
Edit: I see this has already been covered. You are wasting everyone's time starting a second thread.
I do not see a private message from you!
@andreaferns120472 I have flagged to issue to a moderator, on the original thread, so please watch that for updates as it looks like it was missed, which can occasionally happen.
