I am sure almost all of you have been frustrated with your wifi. At some point you get fed up and decide it is time to upgrade. You read the reviews. Look on Amazon for buyer reviews. You finally narrow down your choice. You choice is most likely an AP with more power, longer range, and higher speeds. This new AP will have the power to blast the wifi signal to all your mobile devices.
But almost all of you will make the transition and shortly discover things are not that much better.
Why? Because as Arstechnica points out almost everyone identifies the problem incorrectly.
The problem is 2.4ghz is crowded and more power does not improve things. This is a digital issue there are too many bits trying to get on the 2.4ghz channels. So move to 5ghz by turning off 2.4ghz. Unfortunately leaving both radios on is going to too many times leave you with the 2.4ghz collision problem.
