I just got BT infinity installed today. I also got the dual band AC wifi dongle 900 But it will not register on my PC. I tried installing the drivers for it but i noticed they are only for the 600 model. I know the Home hub 5 just came out along with the new dongle so is it just a case of waiting for drivers to be realesed?
The link you've provided is still to to drivers for the previous Dual Band 600 model (802.11n) and not to the current (at time of writing) Dual Band 900 model (802.11ac) model
Connect to the internet via an ethernet cable. Plug in your 900 dongle (won't be recognised). Go toDevice manager and dongle should be listed under Other. Highlight dongle and then right click mouse. Select "Update Driver" and then the 900 should be up and running.
Realise this is an old thread but I hit a similar problem with the dongle not being recognised and no drivers with the Windows 10 DVD when upgrading an old PC.
I eventually located the correct driver using another PC and copied the file into 'Downloads' on the PC being upgraded. Double-clicked, i.e. ran, the new driver and all loaded and worked fine.
The correct driver for the 11ac Dual-Band Wi-Fi Dongle 900 was located here (as at date of posting):
Hope this helps
