Just replaced an existing Vigor 2820 that had been acting erratically. Noticed that the firmware on the replacement unit was well out of date so decided to check for current releases. I note that the last draytek firmware update was from 2010 but decided that this was worth having for the range of fixes mentioned (See below). Specifically some issues with DHCP that I had experienced seem to have been resolved. I would normally either update this directly (ie plugged into the unit) or via a wired land connection – NOT across a wireless link !!!
****************************************************************************** Release Notes for Vigor2820 series Firmware Version : 3.3.4.1 (Release) Release Date : 4th October 2010 Build Date : 24th September 2010 Applicable Models : Vigor2820, Vigor2820n, Vigor2820Vn, Vigor2820Vsn ADSL Modem Code : 232201 (Standard) Locale : UK Only / Annex A Only ****************************************************************************** IMPORTANT NOTE: Important Note: Firmware 3.3.4.1 provides significant improvements and new features for Vigor2820 series owners. It is possible that if you are using older firmware and retain your old configuration, you could experience difficulties or unexpected operation. We recommend firstly taking a configuration backup of your router before upgrading and retaining a copy of the older firmware in case you want to revert back to it later (old firmware versions are available from, ftp://ftp.draytek.com ). Upgrade to this new firmware locally only (i.e. when you are with the router, not remote to it). After you upgrade to the new firmware, check the operation of the router and ensure that it is operating correctly. If not, we recommend upgrading the router again but use the .RST file which will reset the router back to factory default settings; you will then need to configure the router from scratch. NOTE: 3G modems listed here indicate drivers have been added but does not confirm compatibility with UK Operators. For the list of officially supported models please see the Vigor2820 specification page http://www.draytek.co.uk/products/vigor2820.html [Improvements and Corrections] 1.
