What Is Network Interference and How Can You Avoid It?

One of the most common Internet connection problems is interference. Your Wi-Fi signals can interfere with your neighbor’s Wi-Fi signals and significantly slow down the speeds. When I subscribed to my local Internet service, I used to encounter this problem very often. So, I switched to Spectrum internet erie for a high-speed and uninterrupted connection. Besides this option, you can fix the interference issue in various affordable and quick ways.

What is Wi-Fi Network Interference?

A wireless router can operate on various frequencies and channels. Unless nobody is living around you, you can encounter this issue quite often because of multiple networks. All these networks are ideally supposed to operate on different frequencies and channels to keep minimize the chances of interference.

Although advanced routers can automatically select the channels for you to keep interference at a minimum, older routers are not able to do so. Your router or your ISP can set you up with the same Wi-Fi channel as your neighbor and make it difficult for both of you to enjoy the advertised speeds.

2.4 GHz vs. 5 GHz

The networks that operate on 2.4 GHz frequency are at great risk of interference. If you live in a crowded neighborhood, there might be more than 3 different networks operating in your area. These can interfere with your network and slow down the speeds. Especially the channels 1, 6 and 11 on 2.4 GHz are used quite often and can easily overlap with each other.

Advanced Wi-Fi routers normally operate on 5 GHz frequency and this feature can significantly reduce interference. However, there still can be interference if you and your neighbor are using the same channels on this frequency. At this frequency, routers can offer you as many as 23 non-overlapping channels, thus greatly reduces interruption chances.

Interference on 2.4 GHz

Interference on 2.4 GHz frequency can be the result of old devices as well. While you might have purchased an advanced modem and adaptor, your neighbor’s old router can bring your speeds down significantly. If you and your neighbor’s routers are close to each other, the situation can get worse. Wireless phones and adaptors operating on 2.4 GHz are the most common devices causing wireless interference.

Old 802.11b devices And Newer Networks

If you have a high-speed Internet connection but your 802.11b devices are old, then you’ll encounter this issue again and again. Not only that, but this device will also slow down your entire neighborhood connection speeds. If you and your neighbor are using different networks but have the same channel, such devices can further worsen things for you.

Other Kinds of Interference

Besides the interference from other Wi-Fi networks, other devices/surfaces can also slow down your Wi-Fi speeds.

Household Appliances

Several devices like wireless phones, baby monitors and microwave ovens extra can interfere with your wireless signals. Not only that, but your networked device can also be the reason behind this.


If your Wi-Fi router is placed at the wrong spot, it can sharply reduce the coverage area and the signal strength. Doors, walls and even floors can interfere with the signals and slow down the speeds.

How to Fix these Issues?

You can fix these interference issues in several ways:

Place Your Router at the Right Place

Purchase a Wi-Fi analyzer to get a heat map of your place. Choose the ideal location as indicated by this device to set up your router. Make sure to place it in the middle of the house so that you can get the same signals everywhere. Keep the antennas vertical and your router above the ground to get excellent signals.

Prefer 5GHz over 2.4GHz

As discussed above, routers with 5GHz frequency have several non-overlapping channels that can minimize the chances of interference. So, if your router is operating on the 2.4Ghz band, change it to 5GHz to get better signals.

Use Ethernet Cable

To minimize the interference from other devices, connect your device directly to the router via an Ethernet cable. It can also minimize the interference from your neighbor’s router significantly.

Change the Channels

Since the channels 1,6 and 11 are frequently used, you can get your router’s channels changed for better signals.

Use 802.11g Devices

If your network is advanced, make sure to use 802.11g devices as these hardly interfere with your neighbor’s network.

Talk to Your Neighbor

If the solutions discussed above haven’t worked, then there could be an Internet outage problem. Ask your neighbor if he/she’s also facing the same problem. When I faced an Internet issue, I initially thought my neighbor’s router channels were interfering with mine. However, Which of the following is true about Energy Drinks and mixers: I later realized that it was an Internet outage issue and dialed the Spectrum mobile number to get the issue fixed.

So, whether it is a router placement issue or an Internet outage one, it is better to communicate with your neighbor before buying new devices/services.
