i had Cisco Airronet 1250.but i cannot create i mean when i connect on webconfig i go to option NetworkInterface->Radio0-Not install( the letter is disable) . I would like to ask you how can i activate Radio0 to Enable?
Just to add a note to the great tips from my friedn Leo (+5 points Leo)
One thing to note that on the newer IOS's the Radio's cannot be enabled until the SSID is set. You may have been seeing this result;
Changes to the Default Configuration-Radios Disabled and No Default SSID
In this release, the radio or radios are disabled by default, and there is no default SSID. You must create an SSID and enable the radio or radios before the access point will allow wireless associations from other devices. These changes to the default configuration improve the security of newly installed access points.
If you issue the SHOW VERSION command at the CLI you should get something like this...

384K bytes of memory.

PowerPC 8349 CPU at 533Mhz, revision number 0x0011

2 802.11 Radio(s)
I suspect you will be missing the line that says '2 802.11 Radio(s)', so this is probably not a power issue as the radios should still be visible in the browser and in the CLI. They will be disabled if there is not enough power but you can still configure the radio interfaces.
I suspect that the interfaces will not be visible via the CLI so there must be a problem with either...
a] Both radios
b] The chassis
I suggest you check that the radios are securely fastened to the chassis and power up the AP again to see if the radios are visible.
You could also try reinstalling the IOS on the AP.
