Does Wifi have any form of direct error correction?

I have what I suspect is a malfunctioning wireless access point, the symptom of which is that OS X sometimes says "your connection may be compromised" and disconnects for a minute.

As far as I can see, looking at the dmesg lines that say

AirPort:  Message Integrity Failure detected (G)

this means that some decrypted packet has the wrong value for some cryptographic message authentication code. It seems very strange to report this, since "your connection may be compromised" when it seems that it is more likely due to interference - is there any formal error correction so that interference can be detected? If the wifi stack can see that the error rate reported by the FEC is high and therefore causes a less scary message?

Wi-Fi (all versions of 802.11, including the original "802.11") use forward error correction.
