What Is Asus Router B/G Protection And Should You Use It?

Asus routers have gained a household brand over the years, which is understandable given how reliable they have gotten on high-quality internet connections.

While there are numerous alternatives on the market, today we will look at the Asus router and its well-known B/G protection and features. You may not be aware of this great function, but many people are curious about what it is for and whether or not they should use it.

Because this is about wireless networks, we will go through certain concepts that you need to be familiar with in order to properly grasp the Asus B/G protection.

What is a Wireless Network Mode?

Wireless is currently featured in nearly all gadgets for your home and workplace since it is the easiest way to connect to the internet. Wireless signals are carried by routers and modems and reach devices in two bands: 2.4GHz, and 5GHz.

Both are utilized on a daily basis and have somewhat different characteristics. The 2.4GHz one has a lower frequency and is better for covering greater regions because it can send the signal farther. However, in comparison to the higher 5GHz frequency, the internet connection might be a little sluggish.

On the other side, we have the 5GHz band, which is ideal for shorter distances and offers incredible speeds and responsiveness.

Remember that most gadgets run on the 2.4GHz range, which is one of the reasons why this band and its channels might become congested and even slower than usual.

Aside from the operating bands and channels, you can access and alter several extra characteristics with wireless networks via the router interface. This may involve switching Wi-Fi modes and encrypting data.

Wireless modes vary for each device that connects to the router and maybe switched between G, BG, and N and combined. Wireless modes are analogous to radio stations, and you pick the best one for your equipment. 

Most devices currently use the same data range and frequency, however, it is adjustable.

Furthermore, certain routers, such as the Asus, have extra wireless options that allow or deactivate B/G protection.

What is Asus B/G Protection?

B/G protection is integrated into certain routers, such as Asus, and acts as an additional layer of security against Wi-Fi signal interference.

You can utilize 802.11b client devices in 802.11g networks with B/G protection. To put it another way, this safeguard exists to allow older devices that utilize certain protocols to connect to the internet.

So, if your devices are more than 5 years old, they are unlikely to be able or compatible with modern routers, which is one of the reasons why Asus still offers wireless B/G protection.

Is it necessary to enable the Asus Router B/G Protection?

Many consumers come across this command or function on their Asus routers and are unsure if it should be turned off or on. The answer is really dependent on the user’s choices and whether or not any devices will use this protocol.

The router’s default option for this function is off or auto, and you may enable it manually. While it is a nice alternative to have in case any older devices are unable to connect to the internet, it is generally recommended that this function be turned off.

The rationale for this suggestion is simply to leave the functions as they are because tinkering with the router and its settings might wreak havoc on the entire network’s connectivity

Toggling this option on will significantly slow down the internet for all devices, which cannot be considered a positive thing.

As a result, we recommend using the B/G protection function only if you have devices older than 5 years and cannot access the internet otherwise.

Tips for Using Older Devices

We can now explore this issue further now that we are familiar with the term B/G protection and understand that it is utilized for older devices. We said that this function can be a great addition to your router, but we also know that it might cause the entire network to slow down.

After going through this article you might wonder, are there any additional dangers when it comes to older gadgets?

Mobile phones

Mobile phones are becoming an integral part of our everyday lives, serving as more than simply a method of communication. 

Because competition is strong, this is one of the reasons firms are spending so heavily on new models. However, because new models can be rather expensive, many individuals keep their older smartphones and use them on a daily basis.

Although this may be a more cost-effective alternative, it is not the safest choice for the device or the network to which this phone is connected. Major security updates are missing since older models are not updated on a regular basis or at all. 

This could give malware and other dangerous applications easy access, allowing them to penetrate not only your phone but also the whole network.

Furthermore, older devices only support weaker encryption methods, which might be detrimental to an internet connection. Although encryption methods may be adjusted, adopting weaker ones may result in less network and data security.

This is why we recommend that you get newer mobile devices or, at the very least, maintain your present ones as up-to-date as possible. Although purchasing new ones is expensive, it may save you a lot of headaches in the long run.


Routers are another important piece of equipment that should be no more than 5 years old, ideally less. Because these devices represent the network’s link, they must be updated on a regular basis to ensure peak performance.

Updates are critical not just for internet speed, but also for security and firewalls. Because this is the initial line of protection for your whole system, it is critical that it runs smoothly.

The absence of updates is the issue with older routers. Every new router is optimized, and upgrades are issued for a few years until something new is introduced. Because teams are dedicated to developing solutions and firmware for new models, older models fall behind.

Without a suitable security patch, the older router compromises all network devices as well as your personal data.

Why are Asus routers so popular?

You may be asking why we are discussing Asus routers, but the answer is simple. They are highly popular, with many people owning one and in search of the right answers. 

It is not unexpected given that they work with a variety of internet service providers and have a reputation for producing high-quality equipment.

Asus routers are among the oldest on the market, although new versions are released each year to meet consumer demands. They are well-known for being secure, quick, and dependable, and even the most demanding users like gamers and engineers endorse them.

Asus routers are excellent for wireless connections because they include many antennas that cover wide areas and offer a strong signal on both the 2, 4GHz, and 5GHz bands. 

In addition, there are other options available on the router, such as wireless mode B/G protection, which can really come in handy when you don’t have the newest model available.
