Project is done.
Tested roaming by connecting to WiFi and having the client walk throughout the house and I could watch his traffic switch between the AP’s. Everything is nicely packaged in the rack. Happy customer. I am happy with how it turned out.
The Mikrotik stuff wasn’t bad to work with at all. Had it up and running in about 20min. The longest part was trying to get the modem to grab an IP address from Comcast. Once that was done the rest was gravy.
