You may notice that your DrayTek Router randomly reboots if you have a Sonos music system on your network. Sonos causes Draytek Router to Randomly Reboot
This problem seems to be associated with the combination of Sonos and DrayTek router on the same local area network (LAN) There doesn't seem to be a pattern to this DrayTek random Router reboot, although we have noticed the Router reboot issue will occur in the following scenarios:-
- Streaming Radio from the Internet
- Streaming Music from Spotify or Napster
- Just the Sonos app running on a Smart Phone or Tablet
- Any Combination of Sonos Play 1 or Sonos Play 3, Sonos 5, Sonos Playbar
The Sonos equipment runs in an unusual configuration which is different to a lot of other network devices in that it uses Mesh Network Topology to maintain its own network connections to each of its peer Sonos devices which are on the same Local Area Network (LAN).
Although from our investigations the problem would appears to be with the STP Protocol implementation on the DrayTek router, which causes the random router DrayTek Router reboot issue. Sonos causes Draytek Router to Randomly Reboot
The DrayTek Router random reboot issue doesn't seem to be limited to just one model, we have tried the following DrayTek Routers with Sonos equipment:-
- DrayTek Router 2820n
- DrayTek Router 2750n
- DrayTek Router 2830n
- DrayTek Router 2850n
- DrayTek Router 2860n
After spending many, many hours on this annoying issue, we believe we may have a work around until DrayTek produces a fix for this issue:-
- Turn off UPNP Services
- Turn on IGMP Services
