Could you tell me here or please point me to the most recent documentation how to setup guest wifi for both 2.4Ghz and 5Ghz with the following requirements:
It has its own DHCP server
It has a separate subnet (like 172.20.15.0/24)
Both internal wifi networks and guest networks can operate flawlessly
Guest network devices can't access internal network devices, they can only connect to each other and the internet
I need to limit overall DL from the internet speed across all devices in both guest networks to a certain threshold (like 25mbit) but do not limit UL/DL speed of the devices in the guest network when they connect to each other (like for file sharing)
