Welcome to Vodafone Community
Just moved to Vodafone Broadband from SSE (and previously BT fibre). I have used the original BT Openreach modem (Huawei HG612) which handled the VDSL - connected to an Apple Time Machine. I wanted to use the same setup, but there has been a lot of discussion that the Apple Airports cant be used because they can't set the VLAN id to 101. I managed to get this setup to work though by doing the following....
Firstly, I called Vodafone to get my username and password on 0808 003 4515.
What I did then was to unlock the Huawei modem by using the instructions listed here:
I found the firmware at: https://mega.nz/#F!LdJFDIJL!e_E1twsIg2kTet8mPjrb4w
and chose the B030SP08 folder and downloaded the bcm96368MVWG_fs_kernel_HG612V100R001C01B030SP08_webgui firmware.
I flashed the modem, and checked the VLAN id - which was set to 101 - as Vodafone required already - so i wonder whether flashing the router is really necessary - unless the flashing defaults some of the settings.
Changed the Time Capsule's internet settings to PPPoE and put in the username and password supplied by Vodafone. I also set the DNS as the google ones 184.108.40.206 220.127.116.11. I don't know which ones Vodafone use - didn't ask...
Set the Network options to DHCP and NAT and everything worked well.
@Froggy I'm glad you managed to get your Apple Time Capsule setup okay.
I'm sure this information will be helpful to other users.
