HA causing router to timeout

Hello,

I have been using Home Assistant in my home for a few months now and have loved it. A couple months back, there was this weird problem where my internet router would freeze almost every 10 minutes on the dot and prevent a signal from going out for roughly 30 seconds. I got a replacement router and that solved the problem for a bit.

The problem is starting to come up again, and I’ve found that disconnecting the ethernet cable from my router solves the problem. This leads me to believe it’s something related to a signal being sent/received by HA. I’ve looked at the logs but see no errors outside of losing connection. I don’t really know where to start to look to find out what might be causing it.

Router: NETGEAR Nighthawk Modem Router Combo C7000
ISP: Xfinity

Any advice or tips would be greatly appreciated!

Nothing HA could do should be able to disturb the router.
The fault must be in the router, so see if there is a newer firmware for it.

Did you add the speed test integration and have it run ever 10 minutes maybe?

Do you have dlna active in your router? Had same problem here. Disabled it and now its over.

How many WiFi clients do you have on your LAN?

Thank you everyone for the input. I think I may have figured it out.

I am using a ZWave/Zigbee dongle in the USB port and had it next to my router. I was reading that the dongle should be further away from the router to avoid signals interrupting each other. There haven’t been any issues since adding some more distance yesterday afternoon. Best I can assume is the signals were somehow causing problems with the router?

The only other change I made was disabling an integration I downloaded from hacs, but haven’t had a problem after enabling it again. Might be able to rule that out as the problem.

I’ll keep monitoring and see, but I have my fingers crossed that was it. Thanks again!

Keep looking.

ZWave doesn’t operate in the same radio spectrum and comparatively is a fraction of the power of a wifi access point.

What this means is there’s. No way ZWave sas. Impacting the setup. Wifi can absolutely make ZWave controllersfreak out if they’re too close or in the same usb bus due to the sheer relative power.

So while I’m glad it seems cleared do not by any means consider it solved. It’ll come back.
