Security with Compression on Atheros cards

“On Atheros-based cards, encryption (WEP, WPA, etc.) does not work when compression is enabled.”

From this page:
http://www.mikrotik.com/testdocs/ros/2.9/interface/wireless.php
In the Notes for Wireless Interface Configuration.

Is this for real?
Is their a plan to change this in later versions?

Ask Atheros, the limitation is in the chipset.
The same logic that is used to encrypt can be used to compress instead.

Thank you very much for the reply, I’ll direct my questions to them.

to believe compression serves the same purpose as encryption is false.
just because it looks garbled, does not make mean it is not easily reversible.
In fact compression is designed to be easily decoded.
since this also appears to be an adaptive form of compression, the sender will include information necessary to decode the encoded tokens, before any such encoded tokens are transmitted.
sending compressed material is as secure as sending unencrypted material.
