I'm trying to get my 2820n to connect to Sky's Fibre Unlimited service via the BT Openreach modem. DrayTek sent me firmware 3.3.7.2_RC3 but it still doesn't work.

Under WAN2, I have selected PPPoE and typed my Sky username (...@skydsl) and password leaving everything else set to default, rebooted, but nothing. Under Multi-PVCs I tried changing Channel 1 to MPoA and then tried every encapsulation, with a VPI of 0 and VCI of 40. Again, it doesn't work.

Does anyone know what configuration I should be using?

Ive got the exact same situation and need help aswell.

Well I'm now connected on Sky Fibre Unlimited using only my 2820 and the BT Openreach modem!!! Here's how I did it...

With the Openreach modem connected to WAN2:

1) Upgrade to firmware 3.3.7.2_RC3a
2) Reset router to factory defaults
3) Under WAN > General Setup, disable WAN1 and make sure WAN2 is enabled
4) Under WAN > Internet Access > WAN2 > Static or Dynamic IP, enable this mode, use "Obtain an IP address automatically" and specify the Router Name as your sky username and password in the following format: aabbccddeeff@skydsl|password
5) Set the MTU value to 1478 (this is what my Sky router was set to)
6) Apply the settings and reboot

It takes between 2 and 4 minutes to connect. If the connection drops, it reconnects in a few seconds.
