Does 5GHz WiFi Go Through Walls?

Will it go through walls? Or, is this what is destroying everything? Within this guide, you’re going to learn more about the 5 GHz Wi-Fi band and whether or not it can go through walls.

  • Dual Bands

First, you’ll want to learn more about the different Wi-Fi bands. In the early days, most routers worked on one band and that was the 2.4 GHz frequency. Today, most routers are dual-band but there are some that work on three bands. The two frequencies include 2.4 GHz and 5 GHz.

While they can help you access the Internet, there are some minor differences between the two. It is pertinent to learn as much as you can about these differences. For instance, the 5 GHz band is an upgrade.

If you need faster speeds, you’ll want to stick with this one. Either way, having dual bands is very beneficial since this can help you avoid interference problems. With the 2.4 GHz band, many devices operate on this frequency. This includes wireless routers, baby monitors, telephones, and other things. By staying on the 5 GHz band, you will be able to avoid these issues and get the fastest speeds.

  • Selectable Or Simultaneous

When browsing the market, you will find routers that offer selectable bands. This is a good option for some but not many. With these routers, you will have to choose a band. The only problem is that you’ll only be able to use one band at a time. If you want to use the 5 GHz band, you’ll have to flip the switch and all of your devices will need to switch to this band.

This can be a problem since older devices may not be compatible with this band. Alternatively, you should consider buying a simultaneous dual-band router since these models are much better.

With this device, you’ll be able to access both bands simultaneously. The router will send out a signal on both lanes ensuring that all of your devices can connect to the Internet. Furthermore, you’ll be able to use the slower 2.4 GHz band for browsing the net and reading books. You can use the faster 5 GHz band for streaming movies and gaming online. Ultimately, it is best to buy a router that fits into the simultaneous dual-band department.

If you’ve got extra money to spend, you may want to consider upgrading to a tri-band router though. With this type of router, you’ll have access to 1 2.4 GHz signal and 2 5 GHz signals. This is even better for eliminating network congestion and interference.

  • 2.4 GHz Vs 5 GHz

While the 5 GHz signal is superior in many ways, its range is slightly limited. This is why many people suspect that the 5 GHz signal cannot pass through walls. Before moving forward, you’ll want to learn more about the differences between the two bands. Once you’ve done that, you’ll have an easier time figuring out which band is going to work well for your device.

First, you should know that the 2.4 GHz band is significantly slower. When using this band, you’ll be able to get maximum speeds up to 600 Mbps. However, the range is going to be better.

If you’re staying further away from your router, you may have to use this band no matter what. Alternatively, you may need faster speeds. If so, you’ll want to make sure that your device is connected to the 5 GHz band. This band can provide you with maximum speeds up to 1300 Mbps. The only downside is that this band’s signal is weaker. So, you’ll have to stay closer to your router to maintain a steady and reliable connection.

When browsing the web or chatting on Facebook, you’ll want to use the 2.4 GHz band. If you’re going to be download or uploading massive files, you’ll want to use the 5 GHz band since it is faster. Gaming would be best on the higher band as well.

  • Signal Comparison

The 5 GHz band is better in many areas but it may not be the best. If you’re trying to get the longest range, you’ll want to stick with the older 2.4 GHz band. The truth of the matter is that the lower frequencies can pass through solid objects must easier. This means that the 2.4 GHz signal can penetrate walls, doors, and other objects. This may not happen with the 5 GHz band. With the higher band, you’ll have to take steps to eliminate objects that may interfere with the signal.

For instance, you may need to keep your door open. You might have to remove mirrors from the room. It is best to keep the router in view at all times. This is the best way to ensure that you’re going to maintain a reliable signal when using the faster band. Also, you have to realize that the 2.4 GHz band is more common since it is used by a variety of other devices.

While you may not experience any interference on the 5 GHz band, you probably will on the lower band. If you’re experiencing interference issues at home, you can likely eliminate this problem by connecting on the 5 GHz band frequency.

Does 5GHz WiFi go through walls? It likely will. However, it is not as good in this category as the 2.4 GHz WiFi alternative. When you need the longest range, you’ll want to use the 2.4 GHz band.

  • Compatibility

You’ll want the fastest speeds possible. After all, you don’t want any lag when streaming 4k videos from Netflix. And, you don’t want to be fragged in your favorite online game because of network lag. So, you should take advantage of the 5 GHz band when possible.

The only problem here is that some devices are not compatible with this frequency. This band is slightly newer so some older devices will not work with it. If you own a device that was made in 2009 or earlier, it may not be compatible with the 5 GHz frequency.

By accessing the device’s Wi-Fi settings, you should be able to choose the band that you want to use. If you do not see an option to switch to the 5 GHz band, there is a good chance your device is not compatible with it. Then, you’ll have to continue using the slow 2.4 GHz band. The good news is that you’ll get a better signal anyway.

  • Know The Difference

There are two main types of wireless routers, the 2.4 GHz and dual-band. It really depends on your wireless needs as to which router will work best for your home. However, it is almost always recommended to go with the dual-band router. Why you may ask? Well, because it has two frequency bands, the 2.4 GHz and 5 GHz.

What is the difference between these two frequency bands? Both have pros and cons, which is why the dual-band wireless router will always be your best option. With this router, you can say “you get the best of both worlds.”

Which Option Is Best For Congested Wi-Fi Systems?

Which Option Is Best For Congested Wi-Fi Systems

If you classify your Wi-Fi system as “congested”, it is likely you have a lot of connected devices that are utilizing bandwidth around the clock. With the introduction of smart home systems, a lot more pressure has been put on the wireless router to perform at its maximum potential.

One smart home system could have anywhere from one to 15 or more connected devices. First and foremost, the smart home system must have a hub. This is the gateway from the wireless router to the connected devices. From here, you probably have a smart thermostat, Bluetooth surrounds sound, security system, and so on.

With so many connected devices, your wireless router will surely experience interference signs at some point in time. The option may be the 5 GHz frequency band. This is mainly due to the fact that this Wi-Fi frequency is generally not as congested as the 2.4 GHz frequency band. With this said, there are a few cons to utilizing the 5 GHz frequency band. One con worth nothing is the inability to penetrate solid objects.

While the 5 GHz frequency band may be considered the faster option, the 2.4 GHz frequency band will offer a longer wireless range in homes with a lot of physical barriers, such as walls, ceilings, and concrete.


Will the 5 GHz frequency pass through walls? In most cases, it will. However, the 5 GHz band is weaker in terms of range and signal strength. If you’re going to be venturing further away from your router, you’ll want to use the 2.4 GHz band. This will help ensure that you maintain a reliable connection with every step.
