I am sure that Draytek UK support emailed me a link to download the beta firmware for my 2820, sadly I can't find that email now (and I've moved onto using a 2925, I do still have the 2820).

Found this FTP site, but not sure the RC is on there.

ftp://ftp.draytek.com/Vigor2820/Firmware/v3.3.7.2/

That said, I've just managed to track down a copy on my old PC from when I was trying to get it to work, along with a link to a thinkbroadband post I made at the time.

You are a star!!!!!! I will try this right now. I just lost a bidding war on a 2830n on ebay if this works will save me some money!

Thankyou for your time an efforts in this topic.

Just wanted to return an let anyone know that this is the right firmware I was looking for an my 2820n now working fine with SkyFib using an OpenReach modem.

Glad to hear it worked & saved you some money
