For anyone using the Vigor2800, Vigor2800G, Vigor2800V or Vigor2800VG routers, a new firmware has been released. It is version 2.6.3.1. The firmware must be upgraded using a network cable - it cannot be done over the air. If you are upgrading from the base UK release version then you *must* use the v28ve2631.rst firmware file and *not* the v28ve2631.all firmware file.
'rst' files will factory reset your router so that all your configuration changes are lost so you will need to note down all of your configuration settings.
'all' files just upgrade the firmware whilst retaining your configuration settings.
The firmware upgrade utility looks for '.all' files by default so it's very easy to pick the wrong firmware file! If you flash the router with the v28ve2631.all file then the router will become unusable. You will notice this when the 'ACT' light stays on and the 'QoS' light starts flashing rapidly. This can prove somewhat frustrating but all is not lost. If the Draytek router detects corrupted firmware and/or settings, it automatically goes into firmware upgrade mode (tftp mode). You must then re-run the firmware upgrade utility specifying the v28ve2631.rst file and the router will be flashed successfully.
The reason I mention all of this is that the release notes on the Draytek Web site do mention this but the release notes included with the firmware files do not mention this! So, it is possible to make a mistake as people may assume that the release notes included with the firmware are more up-to-date.
I have e-mailed Draytek about this.
