The features of the MX build in Wi-Fi are *very* limited and lack lots of features, even basic stuff like disabling a band (like 2.4) or tuning the basic rates. I see it as a low-cost home-office alternative to a dedicated AP. But when you need more than one AP or any flexibility, the dedicated APs are the way to go.
Do we have any links of documentation or video on what do we have currently for Branch routers? I could find something called Rogue access points and channel bandwidth utilization in monitoring and wireless SSID settings in configuration. Are these the only 2 that we have when we look at products like MX64W?
