OS X Yosemite 10.10.2 was supposed to fix all WiFi issues, but that wasn’t exactly the case. Here’s how to fix remaining OS X Yosemite WiFi issues.
Since the release of OS X Yosemite, many users have visited Apple’s Support Forums. Express their dissatisfaction with WiFi issues Apple heard them loud and clear, as version 10.10.1, released in November, clearly aimed to fix WiFi issues for Mac users, and update 10.10.2 released earlier this year. , but nothing else actually happened.
While some Mac users said that the updates fixed the WiFi problems on their Mac, many other users stated that the update simply did not fix it.
Unfortunately, many OS X Yosemite users have been experiencing random WiFi disconnections since the release of the new OS; this is nothing new to OS X users in general, as OS X Mavericks came with the same issues for many users.
There have been many temporary fixes suggested by various users, and while they may not fix WiFi issues 100% of the time, they will at least work temporarily until the issue reappears and we see how this latest update doesn’t. fix the problem, bad news for Apple.
However, a Reddit user is quite a unique fix to WiFi problems that might work for you.
Essentially, whether you experience WiFi issues in OS X Yosemite depends on your router, but it’s by no means your router’s fault. It’s still Apple’s fault. Reddit user mossmaal explains it well:
Wifi works by broadcasting in the 2.4Ghz and 5Ghz spectrum. Just like a highway is divided into lanes for efficient use, wifi is divided into ‘channels’ so you and your neighbor can use the WiFi without generating interference.
Usually your router is smart enough to sniff the spectrum and see which channels are in use. It will then start using the least used channel, much like a car driver searching for an empty lane.
What [has been] Discovered… Yosemite does not work on some of these channels. So instead of all lanes being open, only a few are open. But you computer can’t understand which ones are running, so it doesn’t know how to use a different channel.”
Many users said that they don’t experience WiFi issues on their Macs when using an Apple AirPort Express router, which isn’t too surprising, but those with non-Apple routers have a higher chance of encountering the issue.
So what is the workaround? The user who discovered this flaw recommends that you change your router to 5GHz (if it supports it) and use channel 36, 40, 44 or 48 as the user states that these channels work better for OS X Yosemite.
It also suggests editing your router’s settings by looking for an option under your wireless advanced settings. Try disabling it and see if that helps with your WiFi issues. Otherwise it seems like a problem in the future that only Apple can fix with a software update, I hope they do it quickly because there seems to be a lot of OS X users ready to lose their minds.
