Hi @SuperMario86, welcome here. 

I haven't heard this one before, but it's quite weird the wifi restarts every 2 days. Have you already reset your modem? Does it solve the problem? 

Thanks for your message, this might explain a lot.

There are many other people that complain about the fact that since the latest firmware update every morning their Sonos equipment lost connection and that they have to restart their V10a to regain connection.

Honestly, I would like to avoid reset the modem as I have a lot of things configured (restoring a saved config might also reintroduce a problem).

As I see in the logs, it seems to be like a scheduled restart of the interfaces after 2 days of uptime, it doesn't seem a restart due to an error or config issue.

I totally agree, you should be able to run a router 24x7 without te need to restart it.

It seems that this reset of the wifi interfaces is indeed a scheduled restart and then the question is ... why? Is this a workaround to avoid the V10a crashing due to a memory leak in the wifi functionality?

Ik hope KPN can/will explain this behaviour.

I will notify the engineers. Let's see what they say about the restarts. 

Thank you, please let us know!

I will. 

Any news? It keeps doing this

I will ask @Bart_Z when he is back from vacation.  For now there is no new information, I'm sad to say. 

I asked for an update. Hopefully soon we get more information. 

Any updates? I still have disconnections in the night

Unfortunately not yet. 

Still no news? This issue is there for months, and it is still happening.

No sorry. I notified my colleagues again. 

I heard you've had contact. And if I'm right, the next firmwareupdate will fix it. 

Hello,

yes I had contact!

Explanation is that every 2 days, the router performs a scan to choose the best wifi channel, thus all the wifi connection must be dropped.

Although, I had selected a manual channel, so it is quite strange that the scan is performed anyway.

In the next release, there will be an option to disable the scan.

Thanks!

Alright, thanks for the explanation. 

It is nonsense that all the connections must be dropped in order to perform a wifi scan. Wifi should stay connect 24x7 and if not it should be corrected bij the supplier of the device (KPN in this case).

Per example, my wifi security camera's are online since the last reboot of my router six month ago and that is how it should be.
