You need a good dual band WiFi router, and here’s why: if you live in a dense neighborhood, chances are high that you’ll experience channel conflict or signal overlapping. In English, your WiFi setup might be very similar to that of your neighbor’s — so similar that everyone’s signals are getting congested (i.e. slow). It’s an issue people are experiencing a lot these days because they are using a router they bought several years ago — usually one that only operates on the 2.4 GHZ band.
With a dual band router, however, you have the ability to make use of the 5 GHZ band. Using a WiFi heat mapping tool (Mac users can give WiFi Explorer a try) it’s fairly easy to see what kind of setups your neighbors have. In my neighborhood, EVERYONE is on 2.4 GHZ and nobody is one 5 GHZ. So for me, switching to 5 GHZ would be like driving on the Interstate with zero other cars to slow me down (whereas the 2.4 GHZ band might be more akin to taking a crowded city street, at least for this illustration).
But newer routers are also just inherently capable of faster wireless Internet speeds. Older 802.11g routers top out at around 54 Mpbs whereas newer, more powerful routers can reach speeds of 1,300 Mpbs — that’s 3x faster!
It’s a common misconception that you’ll get whatever Internet speed you are paying for on all of the devices in your home. If you’re paying for faster Internet speeds — say 50 Mpbs or higher — but have a slower, older router, there’s just no way wireless devices like iPhones or iPads, Roku or Apple TV boxes, Internet radios or other devices that rely on WiFi to connect to the Internet are going to reach top speed.
Before I upgraded to a dual-band router, I had a 50 Mpbs Internet connection but, because I had an older router, could only pull about 15 Mpbs speeds on my phone. So, while I did have a 50 Mpbs wired Internet connection, that didn’t hold true for my wireless connections. Hope that makes sense.
Finally, newer, better routers can handle connections to more devices simultaneously which is important if you are trying to be as future-proof as possible. Over the next few years, the amount of devices connecting to your network wirelessly is only going to grow. As smart ...
