Updated, entire network crashing (Draytek routers)

[mark.carter]

similar to this report Sonos causes Draytek Router to Randomly Reboot - Century IT Services

[elite (Nick Honer)]

Yes, although I still have UPNP enabled and has been stable so far

[WAJWAJ]

if all 3 of these are ticked, the router will stay up IGMP Proxy IGMP Snooping and Enable IGMP Fast Leave has been up over 15 minutes now

if you just enable IGMP Proxy it will fall over again after about 5 minutes

I am going to just try enabling snooping and see what happens there

[Liam-Whiteside]

I already had the Application / IGMP features enabled

[WAJWAJ]

Interesting, so could it be a combination of things on the draytek, something i have enabled that you don’t or vice versa

[elite (Nick Honer)]

Different firmware version?

I’m on 3.9.1_BT

[WAJWAJ]

So with just IGMP Snooping ticked seems to prevent reboots, been up 20+ minutes. I do wonder what has changed in HA that would cause this behaviour though

[elite (Nick Honer)]

I’ve been up for 25+ with just IGMP Proxy

[Sinkers7 (Sinkers)]

My Draytek has always had IGMP enabled and with 2023.6.0, it has the network issue.

[WAJWAJ]

both you and @Liam-Whiteside have a 2862, i am using a 2860 and not sure what @elite is using, but am assuming a 2860 too with that firmware version

[elite (Nick Honer)]

Yes I have a 2860

The Sonos article mentioned disabling UPNP, might be worth trying

[Sinkers7 (Sinkers)]

The firmware version I’m using on my 2862 is the latest (3.9.9.1_BT), which I’ve been using since it’s release in March

[Liam-Whiteside]

I’m also using 3.9.9.1_BT

Changing IGMP settings hasn’t helped me. I’ve just disabled UPNP and it’s ben stable for 5 minutes since

[WAJWAJ]

I do wonder if this is a Matter 1.1 update that you pointed out earlier

[WAJWAJ]

Matter (BETA)

Probably better to read that. It refers to IPv6 being enabled internally, IGMP, multicast etc

Same issue - 2023.6 is making my Draytek router reboot, killing the network. I have a Vigor 2762 and have had IGMP proxy and snooping turned on for years. I turned OFF just UPNP in my case and rebooted Home Assistant and it’s been stable since. I’m going back to 2023.5 though until this is understood.

My case is a Pi4 running DEB11 and Home Assistant supervised

[Sinkers7 (Sinkers)]

Has 2023.6.1 addressed this issue?

[robward]

No - I tried 2023.6.1 before turning off UPnP on the router.

Hi all…

I’ve had the same problem here…

Network issues with core-2023.6.0

I have had exactly the same problem… DrayTek 2862 Router. HA OS running in VMware Player, running on Windows Server 2019. Physical machine has 2 NIC’s which are Teamed together. HA VM is using bridged networking. When I upgrade from core-2023.5.4 to core-2023.6.0, my router starts power cycling / rebooting which obviously breaks my internet connection. If I reboot HA core, no change… If I reboot the HA OS, networking is restored but then same problem starts happening as soon as HA is runni…

IGMP Proxy and IGMP Snooping was already enabled on my DrayTek 2862 with firmware version 3.9.9.1_BT, but IGMP Fast Leave was not enabled.

Enabling that 3rd option didn’t help.

However after diabling UPnP, my router and network are now stable and I have been able to keep HA on 2023.6.0 for now.

Hopefully someone will figure out what the hell that was all about!

Cheers… Andy

@everyone: it would be helpful if affected people could follow-up on the question of balloob. Finding the root cause seems pretty important.
