Above is an example of a router capable of broadcasting multiple SSIDs.
The current setup of the telus unit is setup broadcast two SSIDs - the secure primary SSID and the unsecured Guest SSID ( for which you cannot assign a password)
On my older telus modem/router I can easily to into admin and create a dedicated 5g ssid, a 2.4g specific ssid and a general or default mutliband ssid all with different names and passwords.
