I have a wlan that uses both the 5ghz an 2.4ghz radios in our 1131ag's. I'm having some issues configuring the 5ghz radio so it is someone useful.
These ap's were installed after a survey using the 2.4ghz radio of an 1131, so the building was surveyed for G not A. I have turned on the A radio and enabled the ssid to broadcast on both. I can see that some notebooks are connecting to the A radio and have a good or decent connection of -60 to -75. What I have done is disable all of the data rates below 36mbit so that clients don't connect slower than 36.
What is happening is that the clients will connected at 36 or better on the A radio, but then move around the room where there might be less signal for the A radio, but still good signal for the G radio, and lose there connection because they initially connected on A.
I'm running a 5508 controller with the latest version. Is there a better way to make the 5ghz radios useful even though they don't have the same coverage as the G radios?
Also, I have replaced some of the 1131's with 1142's and I was wondering if I enable N on the 5ghz, will I get better coverage than 5Ghz on A?
Haha, thanks Nelson, but I'm only an expert when it comes to Nintendo :)
You're spot-on, the client makes the decision. +5 for that. I've heard that Cisco has a function in beta that will push a client to use one or the other, but that might only work for 802.11n. I'm sadly not a Cisco insider.
As for your other question, Dan, if your 2.4GHz is robust then there's really no need to use the 5GHz, especially if it will cost a lot of money to 'patch' those holes up. However, if you (for example) have neighbors or business devices that produce a lot of 2.4GHz interference, then 5GHz is the way to go. Very few companies have the ability for all devices to use 5GHz, but when it can be used it's generally a cleaner wireless environment.
I'll say this at least. 802.11n is designed to be run in the 5GHz space. It can be run in 2.4GHz, but it's a lot less effective. So you'll likely want to patch those 5GHz holes at some point, but that might be way in the future.

I have created a Powershell script to automatically add a Wireless Guest User on Cisco WLCs. (tested on 2500 Series)
The script should be completely self explanatory.
