Re: Radio 0 is not present in cisco 1142 AP

Vijay,

Changing image and or the boot loader will not fix a radio that isn't being detected. That output is what you see when a radio goes bad. Some AP's last a long time, others don't.

Radio 0 is not present in cisco 1142 AP

Even I tried to upgrade the AP with

c1140-k9w7-tar.124-25d.JA2.tar  , but still it didnt detect the radio 0 . Can I consider this an defective unit?

HI Vijay,

Try the following:

1.  Console into the AP and post the complete "sh log".

2.  Reload the AP.

did u connected this AP to a switch ?? If yes then can u connect another AP to same port on swicth and see if this AP shoes the 2 radio or not ??

If either fails then it probably is a bad radio in the slot,

I would suggest opening a warranty claim on the unit and replacing it. or raise a tAC case.

Hope it helps.

The radio went bad... You will need to RMA it if you have support.

All other Ap's are having bootloader version of

12.4(23c)JA3 , whereas this AP is having

12.4(23c)JA1. And I am not able to find 12.4(23c)JA1 download page , for upgrading in this AP to sort out bootloader version is not the source of issue for this.
