Amazon currently has a three-pack of the TP-Link Deco M5 Mesh WiFi System on sale for just $162.93. This is down from its original price of $299, and makes this a pretty insane deal for anyone looking for a new WiFi router. Especially since a single Deco M5 will run you about $99. So you're getting this essentially for less than a two-pack.
The Deco M5 is a great WiFi router to pick up, since it is a Mesh WiFi system. With it being a Mesh system, it means that it can cover more area without using a signal extender or range extender. Those typically repeat the signal, and thus decrease the quality of the network (usually resulting in slower speeds). A Mesh Network usually has the opposite effect, and gives you even faster speeds. This particular system can cover around 4,500 square-feet which is pretty good to have, and should keep your entire home blanketed in WiFi, no matter how thick the walls are in your home. Definitely a good thing for those that are looking to add some smart products to their home, as a Mesh WiFi Network not only provides great speeds, but it can prioritize some devices over others. So your laptop will get faster speeds than your Nest Thermostat.
This item is also eligible for Amazon Prime's free shipping. Which includes free two-day shipping, and pretty cheap (usually $3.99) next-day shipping if you need it extra fast. If you are not an Amazon Prime member yet, you can sign up for a free trial of Amazon Prime. You'll get 30 days free (if you're a student, you get 6 months), and then it's $99/year (or $49/year for students). Prime members do get a whole lot more than just free shipping though, so be sure to check out the full benefits.
