Apple’s latest desktop operating system has been already installed on more Macs than its predecessor during the same period of time after launch, but that doesn’t mean all users are completely happy with their Yosemite experience. OS X Daily reports that several Mac owners have complained about certain Wi-Fi issues including dropped connections, slow speeds, or an inability to connect to Wi-Fi. The publication offers various tips on fixing these issues yourself, with the simplest being installing a fresh copy of Yosemite on your Mac, rather than jumping from Mavericks to OS X 10.10.

However, there are plenty of other tricks users can try to fix a faulty Wi-Fi connection — which could be caused by incorrect settings or corrupted files dating back to Mavericks installations — without having to go for a clean Yosemite reinstall.
OS X Daily’s complete guide (available at the source link) helps you remove network configuration and preference files and create a new Wi-Fi network location with custom DNS. Even if some of the instructions might sound strange to you, the guide explains all the necessary steps needed to safely achieve these tasks. A Time Machine backup is encouraged before moving forward with these fixes.
Additional tricks to fix DNS and Wi-Fi failures in Yosemite and troubleshoot certain Wi-Fi issues are also available in the guide.
