RADIO INTERFACE FLAPS VERY OFTEN!

Dear All,

I have an issue with a LAP: cisco AIR-LAP1242AG-E-K9

Using the IOS: System image file is "flash:/c1240-k9w8-mx.124-25e.JAO6/c1240-k9w8-mx.124-25e.JAO6"

LAP#sh controllers dot11Radio 0 | i reset

Driver TX blocks: in use 0, high 0, at reset 0, fail 0 drop 0

Last radio reset code: 62

Radio resets - total:21 retries:0 failed:0

LAP#sh controllers dot11Radio 1 | i reset

Driver TX blocks: in use 0, high 0, at reset 0, fail 0 drop 0

Last radio reset code: 37

Radio resets - total:17 retries:0 failed:0

LAP#

I have the above issue, and my radio interface keeps bouncing randomly:

62 RADIO_RC_SET_CHANNEL Radio channel set. Reset while setting channel from Control and Provisioning of Wireless Access Points (CAPWAP).
37 RADIO_RC_IDB_RESET Radio interface reset.

LAP#sh log | i adio

LAP#

I tried to reload the LAP, but had no effect on the fault. I tried to find some more info on cisco forums about the codes or how to remedy them but I could not get anyfurther.

Please let me know if you have any ideas.

Best Regards
