func(10)=80391f04

I noticed that once the router has been running for a few days, connecting to the router management interface via web browser results in the router rebooting. Anyone else having problems? The reboots have resulted in loss of line speed.

Stable here with 3.9.6_BT. Are you running RC4 or BT?

I updated my firmware to 3.8.6_BT 7 days ago and mine's stable too but........

I did disable syslog and the data flow monitor first, rebooted then i used the RST firmware to update.

After rebooting i reconfigured the router and then at the end i re-enabled syslog and the data flow monitor.

Been stable since update.

Two very noticeable differences, before update the router was consistently using i think it was 3% of the CPU and 86% of the available memory.

After update the router is now using 13% of the CPU and only 56% of the available memory, a significant difference for whatever reason!!

I notice there is a 3.9.6.1 on the draytek FTP (not uk yet) that mentions a fix for rebooting when using Wired 802.1X

https://fw.draytek.com.tw/Vigor2862/Firmware/v3.9.6.1/DrayTek_Vigor2862_V3.9.6.1_release-note.pdf

It doesn't however fix my routing issue that came out of the 3.9.5/3.9.6 disaster.

I’m using 3.9.6_BT

Now I’m getting as well

System did firmware recovery to 3.9.6_BT due to reboot too much times

Every time I go to dashboard, effected my FTTC line speed, lost 6mb/s on my download.

Very poor
