Improve throughput by installing a dual band router

So I had this FTTH solution at my home that promised 50 Mbps at all times. On a wired network that maybe possible but on wireless with a simple single band router operating in 2.4 GHz and bandwidth hungry apps, Fortnite, PubG, video streaming, smart TVs, Tablets and smartphones it was becoming difficult to balance things. With Covid, things became worse as online classes are being held at home. So a solution was to be found to this dilemma. I hard wired one smart TV, the PS4 was also hard wired, but then the other TV in another room could not get its share of airwaves. Turned out the 2.4 GHz router was insufficient. So I had another dual band router installed. This thing works in 2.4 as well as 5 GHz bands. It has MIMO antennae that promise optimal performance and auto bandwidth adjustment depending on speed requirement. It also comes with a USB port so You can attach a printer to it. So now the printer is also wireless and can be used from anywhere in the house. The dual band router was fixed on a wall at some height, all things backed by UPS power. Now I can get blazing fast Internet, live video streaming and the TV in the other room is showing much better video quality without jerking.  So if you are getting Internet issues consider investing in a dual band router.
