Wi-Fi is a pretty incredible technology! With it, you can easily spread Internet access across your entire home. When you are on the go, free Wi-Fi hotspots around the world let you do nearly anything online without using up a drop of your valuable data plan. But as much as we've come to expect and depend upon Wi-Fi, it can be a rude shock when it doesn't work correctly.

That's why I've been following this story so closely. Over the past year, many users have noticed a big increase in Wi-Fi problems. But it turns out the bug isn't in your home router or your favorite coffee shop's Wi-Fi signal. Instead, this awful Wi-Fi service has been traced back to one set of gadgets, and in particular, one dumb change made by the manufacturer!

If you use an Apple gadget, you may have noticed your Wi-Fi has been horrible this past year. I'm not just talking about major slowdowns. No, I'm talking crashes, duplicate computer names, and other weird glitches. Now we know why.

Back before Apple released OS X Yosemite 2014, the company used a system called "mDNSRespondor" to handle your network traffic. As a reminder, DNS, or Domain Name System, is what translates internal website addresses, such as 66.210.246.140, to something much easier to understand and remember, like "komando.com."
