Zyxel Multi X ac3000 - Number of Supported Internet Devices

Hi,

My current wireless system has about 33 device with a mixture of Sonos, Apple gear, TVs, cameras etc.  Some only support 2.4GHz, but most are using the 5GHz frequency. However, my router can't handle the demand and has started to act unpredictably, like losing wireless connectivity etc. 

So, naturally I want to move to a system that can handle that number of devices and maybe more as IoT grows.  Can you confirm how many devices are supported?

Thanks in advance.
