Hi there.

I use a draytek 2850n router on the latest firmware 3.8.8.2_232201

When I check the VDSL information on the online status/physical connection page, it says (VDSL Firmware Version: 1412f0 ) . According to the release notes the VDSL firmware should be 1414c3. What do I need to do to get up to the current VDSL firmware? I've tried reinstalling the firmware and it makes no difference.

In case you are wondering, I am trying to figure out why my internet download speed is around 35Mbps using the Draytek (VDSL RJ11 port), but 65Mbps using my ISPs own router. I am using Vodafone's fastest fibre package.

There are different modem code firmwares here:
