Boost your Wi-Fi

One of the best things you can do for your wifi performance is to move your router out in the open. It’s tempting to hide the router away somewhere no one will see, since who wants to stare at a boring, blinking box? But, the truth is, your devices want to be free. Your router is responsible for sending out your wifi signal, and that signal is only as good as its environment; if it runs to any interference, the signal isn’t as effective. Interference can come from physical elements in your home like walls and doors, or other electronic signals coming from devices like microwaves and wireless phones.
Keeping that in mind, try to move your router somewhere free from those types of interferences. If you can elevate the router, such as putting it on an open shelf, all the better. As a result, your connected devices will receive a stronger signal than they would if your router was hidden behind walls, doors, and microwaves.

In a similar vein, try to use your devices as close to your router as possible. There’s no need to sit directly next to your router on your laptop or force your PlayStation and router to be attached at the hip, but if you’re looking for your wifi signal to be the best it can be, you’ll want to stay within sight

You might be used to doing a lot on the internet at once, like streaming a 4K show on Netflix while playing games online with your friends, all the while downloading a series to your iPad. All this multitasking is wonderful, but it puts a strain on your overall internet speeds.
If you’re looking to boost wifi speeds and performance for something in particular, say to download a file as fast as possible, you don’t want other internet-intensive tasks running in tandem. For these times, make every effort to pause those other tasks. If you live with other people, that might involve politely asking friends and family to pause their favourite TV shows for a while.

Firstly, your WiFi speed cannot exceed the speed of your internet connection.
Secondly, the speed you get depends on several factors. One of these is the WiFi technology your router and connected devices employ. The WiFi standard is known as 802.11 with various versions (a, b, g, n, ac, etc). Examine your router to see what standard it supports. WiFi also uses 2.4GHz and/or 5 GHz radio frequency bands.

Routers follow the same rules that all electronics do: If something’s wrong, turn it off and on again. If your internet is acting up and you’re not sure why, toggling the power on your router is one way to get things back to where they should be. However, if you find yourself doing this too often, you might want to find the underlying cause of the problem.

DNS, or Domain Name System, is commonly referred to as the internet’s phone book. When you visit a website, your device goes through a DNS lookup to confirm the site it’s trying to reach. After all, your computer needs to know the website’s IP address, not the name itself. This lookup communicates with a database to see if your entry’s IP address is listed. If not, the search goes out to a larger pool of databases and the end result is sent back, allowing you to connect to the site. If you’ve never tinkered with your internet setup before, you’re likely using your ISP’s DNS, which is usually slower than it needs to be. Luckily, it’s not terribly difficult to switch to a better DNS.
There are lots of good DNS – most are better than your ISP’s DNS.  Search on Google for ‘free public DNS’. Some of these prevent access to malicious, phishing and adult sites and some provide ad-blocking.

If you are using IPv6 then you may need to know the IPv6 addresses for the DNS servers.
