I've just replaced my 2820 with a 2925, using a HG612 as a VDSL modem (same configuration with the 2820 for Sky Fibre). The 2820 was rock solid, but I notice that my 2925 has already rebooted itself.

Is the firmware on the 2925 a bit unstable? I'm running with what I believe to be the latest version: 3.8.0.1

2 more reboots since my initial post. Needless to say I'm not overly impressed

and even more overnight. Everything else remains powered up, and I'm even using the same PSU as I did on the 2820 (same ratings), so I doubt it is that.

Disabled port forwarding (80 -> 80) and a port redirection 81 -> 80, and then it stayed up 4 hours before it rebooted again.

Having disabled wifi it has lasted 5 hours (a firmware reset and basic config only lasted 20 minutes).

Therefore has anyone experienced issues with wifi causing these units to reboot? It was seemingly find before I rack mounted it (using a DrayTek shelf) coupled with wifi extension cables, and the aerials are external to the rack.

Out of curiosity, try disabling hardware acceleration and reverting to firmware 3.7.8.1.

I had an issue with my 2925 rebooting whenever I fired up torrents, turning off hardware acceleration and reverting to firmware 3.7.8.1 appears to have fixed it.
