Ninety nine percent of us use WIFI whenever we connect to the internet with our laptops, smartphones or tablets. What we tend to forget is that if use that (UUGGGHH!) ugly network cable, we can easily double our speed on the internet. Over the last few years wireless router manufacturers like ASUS (my router manufacturer) have done a lot to optimize the wireless connection speeds. As a matter of fact the latest ASUS router, the RT AC68U (www.tomsguide.com/us/asus-rt-ac68u-router,review-2277.html) is one of the fastest and only costs a little over $200. A great deal for cord cutters.
No matter which router you have, there are a few adjustments you can make to ensure you are getting the most reliable and fastest connections. One of the simplest adjustments is setting which channel the router will use. A channel is kind of like a lane on a road. If there are a bunch of wireless routers in your neighborhood or apartment building, many of them will be using the default factory set channel. That means you are all using the same lane. Whoops!
I am not going to get into the details of changing channels but there are a number of FREE smartphone and tablet apps that can show you the signal strength of each channel on your router and of other routers in our area. So check out he Google Playstore or iTunes. Then visit you router manufacturers website to get help to make those channel adjustments.
