You signed up for a fast upload and download speed, but you are barely going over 25Mbps... you realized that upstairs the internet is not quite working, especially when it comes to streaming, and by late afternoon nobody is able to stream anything. There are many variables that affect your internet speed and luckily there is a lot you can do to make it faster.
But first of all, let's name some of the obstacles that are obstructing the way you surf and stream. For instance, there is the thickness of walls. While Wi-Fi signal can go for hundreds of feet in all directions, walls are a big barrier in reaching those distances. The signal can also be affected by the state of your router – how good the antenna is, as well as the processor, and how old the router is.
If you want to achieve a better signal throughout the house, first of all start by resetting the router. This is good way to prevent the IP connection between your laptop or tablet and the router or between the Internet and the router. By restarting the router, you will restart all the systems. Furthermore, you can try by relocating your router. It would be a good idea to place a router centrally because most of them emit the signal in symmetrical circles. Make sure your antenna is placed vertically, not horizontally.
Before you start losing your mind over not being able to watch Netflix, check if other family members or roommates are using the Internet connection for downloading torrents or streaming. Although a router is capable of supporting a large number of devices, it cannot support heavy duty downloading on too many of them.
