We do business class service - all through MT. Redundancy is easy and cheap. Customers get SLA's with 3 nines and we exceed that.
I had lots of Canopy gear in the beginning and ran away from it after year 4. Among other reasons : No Radius. No Syslog. Poor SNMP trapping. No SSH/SCP. No FTP Server. No FTP Client. Bastardized CLI. Cheap Plastic cases. Crappy NAT Daemon. Not Modular. Pathetic packet filtering. No effective Central management. Firmware so buggy it made Cisco look good
Cambium has been trying to fix some of those shortfalls but still it's Stupidly high AP and CPE prices and limited functionality IMHO not a good choice... was once upon a time but not for the past 2 years or more.
