I support two Meraki MX64 routers, they are definitely expensive and have repeatedly caused issues for my clients when their ISPs force an upgrade of the associated modem. Not sure what shenanigans Cisco has done with Meraki, but I have wasted hours with them on the phone trying to get these MX64's to DHCP from a new cable modem.

Ended up swapping in an Archer C7 on OpenWRT with a LTE modem to ensure business continuity for the client while working with Meraki's abysmal support to get their router to work correctly.
