I have a Deco network of 3 M4R's, each in 1 floor of my house. This has been working magnificently for a little over a year now, but since a week or two the network is unstable. I'm losing packets or get high ping results. I've ruled out issues in my internet connection; when connecting my laptop directly to the modem, everything is fine.

My configuration is as follows:

- Modem in bridge mode (no routing functionality);

- M4's connected through ethernet backhaul (confirmed working in the app);

- Connected computer has at least 70% signal strength, either over 2.4 or 5Ghz;

- Tried changing signal beam or mesh toggles; to no effect;

- Latest available firmware according to the app.

It seems my options to change anything is limited. I've tried disconnecting the ethernet backhaul, resetted all deco's (using the reset button underneath), setup the entire network again, swapped deco's per floor, all had no effect. I'd welcome any clues into the right direction. Thanks!

Edit: Pinging an internal machine gives similar results; some packet loss and many high latency returns. This rules out a problem with my internet provider.
