This guide will walk you through how to change your router's channel so you can improve your Wi-Fi performance. Depending on how many other routers and wireless devices are in your local area, how effective this change is may vary.
How to Change the Wi-Fi Channel
Learning how to change the router channel can be a great way to improve your wireless performance, especially if you're in an area where many other wireless devices and routers compete for the same frequencies. It's a relatively simple process on most modern routers, though you will need to login to your router using the admin credentials, so be sure to have those handy if you don't know them by heart.
All routers have a slightly different backend. Yours may look a little different from the screenshots in this guide, but the general steps should be roughly the same. If in doubt, consult your manual or the manufacturer's website.
Connect to your router as an administrator by navigating to its IP address in your browser.
Using your router's menu, select the wireless band for which you want to change the channel. For most routers, this will be either 2.4GHz or 5GHz. You may want to change them both if you make use of both frequencies.
Open the Wireless Settings menu for your chosen frequency.
Look for the Channel option. Select a new channel from the drop-down menu, or input one manually if necessary.
Select Save or equivalent.
If you utilize other frequencies, consider changing their channel too.
Why You Should Change Router Channels
All routers have a default channel. The default is typically adequate for everyday performance, especially if you live separately from other homes and broadcasting wireless routers. However, in busy areas (think apartment buildings), where multiple routers can overlap each other's wireless networks, there is the possibility of overcrowding those same default channels.
However, most routers support the ability to change their broadcast channel, making it possible to change yours to one less crowded, resulting in better Wi-Fi performance.
How to Find the Best Channel For Your Router
When you change the router channel, you could pick a new one at random. However, it's better to change to a channel you know isn't as well populated, as your wireless performance should improve more, or at least not degrade as other routers come online in your area.
To find the least populated wireless networks, you need to use a Wi-Fi analyzer. Not only can you use them to see what channels other routers are operating on, but you can see how much they overlap so you can choose a better channel to use with your router.
