What version of the mwlwifi has been the most stable

Hi, I have recently aquired a WRT3200ACM and am planning to install LEDE on it during the christmas holidays and was just wondering what version of the wifi driver has been stable or if the recent ones are good?

In my experience, drivers included in latest LEDE are quite good; but you can also install updated drivers from here: Pre-compiled updated mwlwifi drivers for stable releases. I am very satisfied with the device, and have faced zero trouble so far.
