I am trying to do following on a standalone 1250 AP:
Configure 2 SSIDs: Main (VLAN 100) and Guest (VLAN 200)
Configure Guest SSID with broadcast on Dot11Radio 0 with 2.4GHz only
Configure Main SSID on Dot11Radio 1 with 5Ghz only
Client device can not see any signal of Main SSID while the Guest one works just fine. I verified that client devices are capable of two frequencies.
But if I change the Main SSID on Dot11Radio 1 to 2.4GHz, clients will be able to connect to it.
I attached configure file below and running IOS: c1250-k9w7-mx.124-10b.JA1
Just a thought: Is it possible that 2.4GHz radio over-writes 5GHz Radio? I rebooted the AP. When AP boots up, I can see 5GHz signal for a short period of time without 2.4GHz signal and then 5GHz is gone left 2.4GHz only...
Just note also... I have ran into issues with various devices that want to see the SSID on the 2.4ghz also. When I have strictly used 5ghz only, some devices would not join or would associate and then disassociate from time to time... just monitor that.

Not really... The client devices are the issue as they decide what they want to connect on. It shouldn't impact the environment much.any time we have both SSIDs on both radios, it's the client count per AP is what you need to watch out for. The ASAP Ethernet is the bottleneck and if it's connected via 10, 100 or GIG, that will make the difference.
