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?
