I upgraded the firmware to the new latest firmware 4.5.2 BT and I immediately noticed the wifi station list only shows 1 client station even though I know I have 10 or 20 devices connected.  They all worked but the station list in the web page was only showing 1.
Later I noticed it kept doing random reboots after about 8 to 12 hours.

The automatic recovery has just now kicked in and reverted back to the previous firmware 4.5.1 BT.  The station list is working again, time will tell if it stays up.

Anyone else have a 2766ax?

I should add that the "automatic firmware recovery" works brilliantly well.

So you have the same issue on a 2766 that I had on a 2866 (see other post)...reverting back also fixed that.

I've reported it to Draytek - they're wanting full debug logs (which is awkward after rolling back).

Australian site has 4.5.2.1_RC1a for the 2866 though - so I've just upgraded to that to see if that's any better.

My firmware is the localised UK version from the .co.uk site.

Support have emailed me to say they will "test in their lab" today and get back to me.

Yep BT / STD makes no difference whatsoever if you're not using ADSL/VDSL

Regardless of that, you're seeing what appears to be the same issue, so will be interesting to see what they say...probably ask you to factory reset and setup from scratch, thats the usual response...
