Runts on interface due to AP

Hi

Lately we are getting a lot of excessive errors on ports where a AP is connected

sh int fa1/0/25 | i error|runt
     669 runts, 0 giants, 0 throttles
     669 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored
     0 output errors, 0 collisions, 0 interface resets

as info i could find :

Excessive runt frames

In a shared Ethernet environment, runt frames are almost always caused by collisions.
If the collision rate is high, refer to the problem of excessive collisions, earlier in
this table.
If runt frames occur when collisions are not high or when in a switched Ethernet
environment, then they are the result of underruns or bad software on a network
interface card.
Use a protocol analyzer to try to determine the source address of the runt frames.

How do i must interprete this?

In wireless collisions are possible so this is 'OK'?

OR

Do we have a problem with the SW running on the AP (all cisco but different types)

Thanks for the help
