When you try to set up a second wireless network you propably gonna
run into this notification:
‘Dot11Radio0: Guest-ssid already existing on ssid STARGATE’
Of course you can set up a wireless network without guest-mode enable but keep in mind that
the access point will not include the guest SSID in its beacon. So the client have to specify a SSID in their
configuration. When you are not in a home environment it’s wise to keep your network secure, by disabling the guest mode SSID.
For this example, we just want to have the client see 2 different SSID.
Both SSID will be on a different subnet.
Let’s say you want to have one SSID for your clients and one for your wireless IP telepones to associate with.
In this example, we continue with the previous example set.
