Hi

I have a pair of M9+ decos with ethernet backhaul. These worked Ok, until lockdown when kids etc were home and hammering the wifi a lot more than normal. I also noted devices would drop off without explanation. Furthermore, I have noted an approx 7% loss in speed vs what I get when I connect directly to the modem (direct connection to modem vs direct connection to Deco M9 master unit).

My biggest concern is with the device capacity, having added even more thanks to Christmas. Would upgrading to more recent versions of the M9+ help (ie v1 to v2), or would it be better to move to an X20/X60 combo?

I have dabbled with the Amazon eero system, which alleviates most of the capacity and loss issues, but does not (yet) have the security (ie Dynamic DNS, parental controls etc) available outside of the US.
