Thanks a lot guys for this tool, but since I updated my mac with it, the wifi keeps disconnecting every 5 min..... How can I solve that ?
Thank you.

I'm having a similar issue. Though in my case the wifi connection remains, the internet connection drops until I disconnect/reconnect to the network.

My wifi will work once I reestablish a connection but only for another few minutes until it drops again.

Could you please check out the beta branch of the tool, which includes changes that may fix this issue. You should restore the original kexts and restart before doing this. (e.g. with the help of the Kext Drop app).

Thanks for your answer but how do I restore the original kexts ?

Sure. First get the Kext Drop app from here.
To go back to the original Wi-Fi kext follow these steps:

  1. delete IO80211Family.kext from /System/Library/Extensions/
  2. open Terminal
  3. type sudo kextcache -system-prelinked-kernel
  4. type sudo kextcache -system-caches
  5. go to /Users/(your user name)/KextsBackup . That's where the tool initially did the backup.
  6. open Kext Drop
  7. drag and drop the original IO80211Family.kext into the window, click install
  8. go back to terminal and type sudo kextcache -system-prelinked-kernel
  9. type sudo kextcache -system-caches
  10. repair permissions with the disk utility
  11. reboot
  12. try out the latest beta

v.1.0.2 was released, which could fix the issue.

Many Yosemite users are reporting similar Wi-Fi issues on the Apple Discussion Boards, even with new Macs. My understanding is that there might be an issue with the new drivers themselves, unrelated to this patch. You can always rollback to the old drivers with the steps I detailed above, but you will lose continuity.

Closing, as there's nothing CAT can do about Wi-Fi speed issues. CAT relies entirely on the Apple Wi-Fi drivers, including their features and their possibly bugs.
In case of issues, the recommendation is to uninstall CAT, which will restore the older, original Wi-Fi drivers.
