I have three Deco X25 devices set up. One is the main interface to the internet. Behind it is an 8 port switch, but I'm only using like 3 or 4 wired connections on it. One of those is my laptop.

I can use wifi fine it seems, but when I'm connected via ethernet to that switch, waking the computer from sleep, even just disconnecting from a VPN, or just randomly while this laptop is awake the whole network will die. Everything gets knocked offline, all smart devices on wifi, all wired and wireless devices on all the decos. Even my phone switches back to 4G and when trying to use the Deco app it gives some error about not being able to find the deco devices.

I have tried removing all settings I can specific to my laptop (no reserved IP address, no port forwards) and it still happens. I am probably going to try a factory reset, but need to note any settings I have otherwise changed.

I'm hoping someone can offer some insight here. Even connections between devices on my LAN are dropped.

This has only started happening within the last month or two, and I have even switched the main deco device to no avail.

Let me know if you have any ideas!
