Migrated to Sky from O2....Draytek Vigor 120 causing issues now

So my account was fully migrated to Sky from O2 on Wednesday this week with zero warning. The first I knew about it was when I had no internet access that evening and after a quick phone call to O2 was told it should only take a few hours.

Cue 24 hours later and according to Sky my line was transferred and active....only I still had no internet access.

I have a Draytek Vigor 120 connected to an Asus RT-N16 running Tomato for my ideal home network. The Draytek was setup to simply pass the net connection onto Tomato to deal with and all was well. Now it seems Sky use different settings (PPPoA I've been told with VC MUX modulation) to O2 which was LLU-based.

After much faffing around I've finally got VERY slow internet connection by setting the Draytek to PPPoA passthrough and Tomato set to "log in" using PPPoE. The modem's web interface shows it's syncing at 20meg but I'm not getting anywhere near that. Since making this change the Draytek only seems to want to connect to my Asus router's WAN port at 10mb half duplex instead of 100mb full duplex like it did before and takes literally 10 minutes to connect so I wonder if this is part of why the net appears to be really slow. Plus each time I restart the thing I seem to get a completely different WAN IP. I know it's not supposed to be a static IP but previously the IP never really changed.

Is it possible to get the Draytek setup to work with Sky ADSL2+ without PPPoE in the same was I had it setup on O2?
 
I'm afraid Sky use MER authentication and as far as I'm aware the Draytek 120 does not support this I'm afraid.

I think the Billion 7800N does and some other devices, have a look on the skyuser.co.uk forums for more details.
 
I've done more digging and seems my Draytek's LAN port could be buggered. Others have reported similar things where it won't connect at anything faster than 10MB half duplex, and when forcing the speed it fails to connect.

I'm not so sure about MER authentication as I'm able to get an internet connection (I'm using it right now), it's just slow presumably because the connection from modem to router is only 10MB and stuck at half duplex, i.e. data in one direction at a time. It's probably the worst kind of LAN connection you can get! lol

Plus Sky have confirmed they allow the use of 3rd party equipment now given the migration from O2. They've given me the username that I'm supposed to use to login with (blank password), plus have confirmed the PPPoA details for me which match whats on skyuser.

This isn't entirely true I'm afraid, Sky ADSL2+ uses a mix of PPPoA and MER and from what I understand, most customers have now been switched to PPPoA (like me)
