When I first ran HA on my Raspberry, everything went fine for a long time. But suddenly, it started to trigger my modem/router (MEO Portugal) to reboot. As soon as I switched off my Raspberry, the problems were gone.
Today, I got a HomeAssistant Green. I started from scratch (no backup was used from the previous system), but the same issue arose again. When HA is running, my modem/router restarts at random several times per day. When I disconnect my HA Green, the modem/router keeps running.
It starts to reboot, all lights are off, and then the restart procedure starts as you switch on the modem/router again.
I haven´t configured anything now, HA is now totally new installed… Just added all devices that were found during the 1st setup… HA found the modem/router… But I didn´t make any changes in the settings.
So if no problem with power and nothing configured that could interact on the IP network, an IP conflict could explain this behavior BUT why not instantly…
Your modem is either defective or garbage and can not handle the amount of connections HA make.
It is probably not the bandwidth used, but instead the number of connections that are the issue.
It´s super weird. I´ve installed the new HA Green today and since then it rebooted my modem 5 times, all out of the blue. My previous HA was running on a dedicated Raspberry, the same issue (but was running without issues in the beginning. I disconnected that one 4 months ago… During that time never a reboot of the modem. But now, with this brand new HA, the same issue is back.
Can be very possible. The modem belongs to the provider. I already tried to have it replaced (this one is at least 5 years old), but they willing to replace it…
A network device should never crash, not even when devices on the network cause extreme situations.
Yours are crashing even when the devices are behaving nicely and within a reasonable low utilization grade.
Means you ran into the very same issue once before but after replacing the PS all went back to normal for some time until recently?
Well maybe the PS is broken again.
Anyway, my experience with those cheap plastic modems provided by ISPs is that they last 3 to 5 years the max before starting to behave errorneous. I would insist to get the modem replaced by your ISP. Or even better if possible buy a better one by yourself which fits your connection type.
I totally agree… I was already insisting a new modem… It´s too old. But you know… ISP´s are not that flexible, at least MEO Portugal isn´t. Best option is indeed buy one myself.
