5GHz Wi-Fi is not always better than 2.4GHz Wi-Fi

Do you have problems with your Wi-Fi connection? Try 5 GHz instead of 2.4 GHz. Sure, 5GHz Wi-Fi is newer, faster and less congested ̵

1; but has a weakness. 2.4 GHz is better suited for covering large areas and penetrating solid objects.

5 GHz vs. 2.4 GHz: What's the difference?

Wi-Fi can run on two different bands: 5GHz and 2.4GHz 5GHz Wi-Fi became mainstream with 802.11n (now called Wi-Fi 4), introduced in 2009. Before that, Wi-Fi was largely 2.4GHz.

This was a big upgrade! 5 GHz uses shorter radio waves, which means faster speeds. WiGig goes further and works in the 60 GHz band. This means even shorter radio waves, resulting in even faster speeds over a much smaller distance.

There are also a lot less congestion at 5 GHz. This means a more stable, more reliable wireless connection, especially in dense areas with many networks and devices. Traditional cordless phones and wireless baby monitors also work at 2.4GHz. That said, they only disrupt 2.4GHz Wi-Fi – not 5GHz Wi-Fi.

In summary, 5 GHz is faster and provides a more reliable connection. It's the newer technology, and it's tempting to constantly use 5 GHz and write off 2.4 GHz Wi-Fi. However, shorter distances can be covered thanks to the shorter 5 GHz Wi-Fi radio waves. By penetrating solid objects, penetrating solid objects is not as good as using 2.4 GHz Wi-Fi. In other words, 2.4 GHz can cover a larger area and penetrate walls better.

You can use both with a router.

Modern routers are generally dual band routers and can simultaneously operate separate WLAN networks on the 5 GHz and 2.4 GHz frequencies. Some are "tri-band routers" that can provide a 2.4GHz signal along with two separate 5GHz signals to reduce traffic jams on 5GHz WLAN devices.

This is not just a compatibility feature for legacy devices Supports only 2.4GHz Wi-Fi. Sometimes you will be equipped with a modern device that supports 5 GHz with 2.4 GHz Wi-Fi.

Routers can be configured in two ways: they can obscure or expose the difference between 2.4GHz and 5GHz networks. It all depends on how you name the two separate Wi-Fi networks.

For example, you could name both networks "MyWiFi" and give them the same passphrase. Theoretically, your devices would automatically pick the best network at any time. However, this does not always work quite right, and in the end, devices connected to the 2.4 GHz network can be connected if they use 5 GHz or vice versa.

You can instead have one network as "MyWiFi – 2.4 GHz" and the other "MyWiFi – 5 GHz". The names do not have to refer to each other or contain the frequency – you can call a "peanut butter" and a "jelly" if you want. With two different names you can choose between the networks on the device. You can still give them the same passphrase to make things easier.

If you have problems with your wireless network and are connected to the 5 GHz wireless network This is always a good idea Connect to 2.4GHz and see what happens.

5GHz may sound newer and faster – and it is – but it is better in smaller rooms If you want to cover a large open space, 2.4GHz is better, so if you want a better Wi-Fi signal outdoors, you can connect to 2.4GHz instead of 5GHz GHz. Or if your WiFi needs to cross some dense objects before you reach it, 2.4 GHz of it will be much more than 5 GHz.

2.4 GHz Wi-Fi should work better than before. If more people switch to 5 GHz, the 2.4 GHz band in your area should be less congested. For annoying devices such as old cordless phones and wireless baby monitors that are being retired for modern smartphones and wireless baby monitors, there should be fewer devices that can disrupt 2.4GHz at home.

There are other ways to do that, of course. You can get a wireless Wi-Fi system and position access points anywhere in your home. However, if you only want a reliable Wi-Fi signal, simply connect to the 2.4 GHz Wi-Fi before expanding the 5 GHz Wi-Fi anywhere.

Wi-Fi 6 makes 2.4 GHz better [19659005] 2.4 GHz was neglected. 802.11n (Wi-Fi 4) supports both 2.4 GHz and 5 GHz. But 802.11ac (Wi-Fi 5) only supports 5 GHz. If you have a dual-band 802.11ac router, you will be running a 5 GHz 802.11ac network and a 2.4 GHz 802.11n network. 5 GHz uses a more modern Wi-Fi standard.

Wi-Fi 6 will fix this problem. The next generation Wi-Fi standard will support both a 2.4 GHz and a 5 GHz network. Various enhancements that give a faster, more reliable signal also reach the 2.4 GHz Wi-Fi. 2.4 GHz is not just old technology left behind.

How to choose between 2.4GHz and 5GHz [19659005] To select between 2.4GHz and 5GHz, go to your router's web interface and look for the wireless network settings. Specify separate SSIDs or names for the 2.4 GHz and 5 GHz networks. You can type "2.4 GHz" and "5 GHz" in the name to make it easier to remember. And you can use the same Wi-Fi passphrase for each one.

Your router may be configured to use the same name for both by default. That means you can not vote for yourself. Your devices automatically choose between them. Separate names give you the choice.

Now you can easily choose between the networks on your device. Go to your device's Wi-Fi connection menu and select the network you want to join.

Once you're logged in to any network, your device remembers the passphrase, and you can simply click to connect to the item you want in the menu. Switching becomes easy and fast.

If 2.4 GHz Wi-Fi does not solve your problems and you still have problems getting a solid Wi-Fi if you have If you're connecting anywhere in your home or business, consider using a Wi-Fi system. This will give you multiple access points that you can place throughout your home and do an excellent job of adding reliable coverage. And unlike a traditional wireless repeater or extender, the wireless network setup process is much simpler for the mesh network.
