Why is my WiFi slow or dropping out?

It’s frustrating when Netflix keeps buffering due to WiFi slow speeds or dropouts. WiFi Interference may be a likely cause. This guide will help you troubleshoot common WiFi problems. All routers operate on the 2.4GHz frequency. Dual band routers are now on the market offering a new, additional 5.0GHz frequency. To learn which frequency is best for you, check out our page on What is WiFi?

Why is my WiFi slow?

Radio waves often experience interference that can disrupt your connection. Interference can cause slow speeds and dropouts. The 2.4GHz frequency is often disrupted by other appliances. Consequently, this can even include your neighbour’s wifi. Appliances that have the potential to interfere are microwaves, baby monitors, radio controlled cars, cordless phone handsets & bases, and security cameras. This is due to the fact that they also operate on the 2.4GHz frequency.  As a result, even your neighbour fixing popcorn in the microwave can make your Netflix movie buffer. WiFi interference can appear even if nothing has changed in your home.

Can I do anything about Slow WiFi?

Yes, you certainly can. First of all, we need to pinpoint the source of the interference. Doors, walls, and distance all can also negatively impact your connection. If your WiFi works fine near the router, then a device such as a WiFi Extender may be the solution. WiFi extenders are exactly as they sound. They extend the range of the WiFi by plugging into a power outlet. They are fairly simple to set up.

If range isn’t the problem, then it maybe interference. To fix this problem, you will need to log into the router.

Go to Wireless Settings, then look for channel settings. Sometimes this is located in basic settings, or it maybe under advanced.

The best 2.4GHz channel recommendations are 1, 6, 11, or 13.

For 5.0GHz it’s not advised to go over 58/80. Apple devices cannot see higher WiFi channels.
