Great router, but there's a problem with the upstream SNR. Over the course of 24 hours this slowly drops to 0 which causes my connection to re-sync. I've since had to switch back to my Thomson router which maintains a constant upstream SNR of 13db and never drops.

My upload speed is also halved when I use the vigor

Has anybody else had this issue?

Unfortunatly I have this same issue... Im with BT Infinity and get double the speeds up and down using stock openreach modem & homehub2.0.

I have tried everything.. totally confused.

I'm guessing it's a hardware/firmware issue and there're nothing we can do

Waste of money tbh

Please could you confirm that you are on the lastest firmware (currently) 1.4.1? Has Draytek Support given any clues about the difficulty?

There's probably something Draytek can do, maybe the 2750 just needs a different modem code (doesn't exist yet)

Well I'm not actually using the router atm, but it was 1.4.1 firmware yes. My Thomson has been connected for 2 weeks straight so its not a line problem.

It's a shame because it a nice router, but clearly something isn't compatible
