I just upgraded and have G+N chosen for wireless. No issues thus far, web admin behaving normally.

I recommend keeping an eye on the system uptime which can be found on the Status page.

I cannot see a common thread at the moment.

For me it appeared to be Wireless N for another user it might of be related to QOS.

Upgraded to 3.3.3_232201 because the shipped firmware constantly rebooted.
A few reboots until I turned off wireless 11b (set to 11g+11n).
Up for 90 hours then a strange dropping of routing (still synced).
Reboot fixed that, uptime now 25 hours.
A lot of WLAN usage from several devices no problems except range (14m through several walls)
WLAN on WPA+WPA2 most devices connect using WPA2
QOS setup but no Objects setup.

see this post also for possible problems with upgrading firmware to 3.3.3

Lesson I think is, ensure you reboot router and ensure it is running correctly immediately prior to upgrading firmware

We had major problems with VPN pass through and FTP downloads prior to this release. Since the upgrade we are able to use VPN successfully, and also FTP is stable again.

With the thing running (relatively) stable, we are now seeing some other issues (which may not be 3.3.3_232201 specific), as follows:

1. Sees some VPN sessions as DoS attacks (in particular TCP Flag Scan and UDP Flood Defense). Proving difficult to get the right balance!
2. Load Balancing doesn't work as configured. We regularly see traffic being sent down the wrong ADSL line, even with specific rules stating not to and no fail over allowed.
3. NAT Active Sessions Table shows the above to be the case.

Point 1 is a work in progress still - would help if the email feature for syslog worked!

Point 2 and 3 are currently with Draytek Support. We have an uncapped and a capped ADSL line so the load balancing issues is proving a show stopper at present.

For reference, the external modem we use is the Vigor 120, of which the latest firmware is in place and has resolved the timeout issues on it.

All told, the uptime for the unit is 400+ hours so far...
