OS X Yosemite is regarded as Apple’s most advanced desktop OS up to date, but, as expected with any new released, there is one issue that has affected many users for a while now. This problem is related to a bug in Wi-Fi Connectivity.
The latest addition, OS X 10.10.1 update was supposed to fix this problem once and for all, at least if we take into consideration the changelog. However, even so, the problem persists and more, and more users complain about it. The good news is that now, develop Mario Ciabarra has stated that he found a working solution to stabilize Wi-Fi Connectivity on Yosemite.
According the Ciabarra, the problem seems to be dealing with the OS’s capability of handling Wi-FI with AirDrop, using a connection called AWDL. The solution asks for you to disable this service, which will be turning Airdrop useless, but, at the same time, it will fix the Wi-Fi Performance related issues once and for all.
In order to do this, users will have to run the Terminal app on their Mac and enter the following command line:” sudo ifconfig awdl0 down”. Next, hit Enter and restart your computer.
This solution is suitable for those who want to solve the Wi-FI connectivity problems, but they do not care whether the AirDrop will become useless. I am sure that the official fix will land eventually, but until then, this is a working solution you should take into consideration.
Yosemite has encountered various problems with the Wi-Fi connectivity since its release, and despite the 10.10.1 update, the problem still exists. Most users complained about dropping Wi-Fi connections, slow internet speeds, and sometimes, the two of them at the same time.
In the same time, it is worth mentioning the fact that the iOS 8 update caused iOS users the same problem. They reported various Wi-Fi issues, but Bluetooth in the same time. Bluetooth problems are something common with Yosemite as well; however, these problems do not affect every user out there.
Apple is trying to fix these problems by releasing the OS X 10.10.2 Beta to testers on the 24th of November. So far, it is unknown whether the beta version has managed to solve the Wi-Fi and Bluetooth problems. Until then, feel free to check out this solution and see if it works for you.
