I see this strange thing. I have 4402 controller and have 50 1142 LAP's installed . I could see in the controller that both the radio's are enabled in the homepage of the controller. But below that , I could see 802.11a radio's down and 802.11g radios are up.
I went to the wireless section and made sure that 802.11a is checked . Any suggestions to help me, why it is down . Also , Is there any fine tuning to be done, for wireless clients with 802.11a/b/g/n client cards to go to A channel rather than going to G channel.
Thanks for the help.
