Hi! I'm having a strange issue with all my Deco S7 units (3 of them), i already have a site configured through the Deco App and joined all my units, they are working (fine?) until you make some network traffic through the wifi or ethernet (i.e doing speedtest). When you do this the main Deco just crash and restart, obviously losing the connection on my devices.

I already tried to configure the site with just 1 Deco, 2 Deco, exchange the main Deco between the other two, router mode and AP mode, disconnecting all the devices from the ethernet and wifi just keeping the main Deco and my ISP router, downgrading firmware to previous version, upgrading the firmware again, change all the ethernet cables with new ones, made new TPLink account and create a completely new site with different name, network, etc.

Anything of this solved the issue, at this point i think the units are just broken but is so strange that the three of them are broken.

I need some advice or comments from people who has or had this issues and how to resolve them or official support.

I found this post from an user who has the exact same problem but there's no response: deco s7 restart every time - Home Network Community

Thank you.
