Stay clear if you need a stable, bug-free router
on 2 August 2014
Time for an less than ideal review!
I bought one of these in December 2013, mainly because it supports various site-to-site VPN set-up (dial-in also), has an Ethernet WAN port and an impressive VPN throughput speed compared to similarly powerful devices from Cisco or Juniper.
I had previously worked with a 2830, and know Drayteks generally to be of great stability and build quality.
Two official firmware version are currently available from Draytek.
Version 22.214.171.124 unfortuantely breaks access to some site using SSL, including the all important Google Mail and Google Drive. In addition, 126.96.36.199 sees an issue where a dial-in IPSec VPN connection will drop every three minutes or so.
Furthermore, I hear that VDSL authentication is buggy.
Version 188.8.131.52 has two problems of its own on the other hand:
- When UPnP is enabled, and ADSL connection will drop every few minutes.
- WiFi access breaks for about 30 seconds every few minutes (it stays connected, but no traffic is going through).
Version 184.108.40.206 was released in April, and since Draytek support have emailed me (and others) several 'beta' versions of firmware that is trying to address those problems.
Some of those firmwares come with their own problems, and have the ability to brick the router. This is unpleasant, as the restore tool Draytek provides only works on Windows XP (and alternative methods don't seem to work at all for this one).
I was sent the latest beta version mid July, and while now all the VPN, UPnP and WiFi issues have been addressed, the SNR can no longer be adjusted on this one.
It would be a great device, but for anybody requiring a stable production router, I recommend looking elsewhere, until all the firmware bugs have been addressed.
I've reverted to mainly using my old router now, and plug in the Draytek only when I'm bored and try to find some more bugs.
Update February 2015: I have switched to FTTC now with firmware 3.7.8
My DSLAM chipset vendor (i.e. the equipment in the street cabinet) is reported as 'IFTN' (Infineon Technologies, which is now the Israeli company ECI).
With this combination, NEITHER of the 3.7.8 VECTOR firmwares work, in that I experienced frequent disconnections (about every 30min) with all four combinations of VECTOR firmware and modem code.
The 3.7.8 STD firmware is stable, although I had to turn SRA off via telnet (vdsl optn sra US = 1, vdsl optn sra DS = 1).
However, I am pleased to say that issues with UPnP, WiFi and VPN have now been fixed, upgrading to three star rating.
The one thing that makes me stick with Draytek is the l2l VPN throughput, much better than any comparable product of this price that I know (though I haven't tried the new Zyxel series yet).
Another problem(?) that has come to light is however that the maximum number of DHCP leases is limited to 256.
For most people, this won't be an issue. This came to light for use in a conferencing venue. The router was configured for a Class A network with a /16 subnet, which offers ~ 65000 available addresses. The 2860 can only assign 256 of those.
