Chances are if you have a newer ASUS router, you’ve probably never heard of B/G protection. Regardless, can it be advantageous to turn the setting on?

The ASUS router B/G protection feature is designed to protect older devices on the same network as newer technology. The B/G protection setting can be turned ‘Off’ or on ‘Auto’ for qualifying routers (usually 5 years or older). To further improve your router’s signal, try moving it to an elevated area with no obstructions.

This ASUS router system, in particular, is designed to help you check what devices are connected to your network and how much bandwidth they’re taking up. This way, if a device exceeds its limits of usage or otherwise causes a problem, you can quickly identify which one is responsible for the issue.

What is B/G Protection?

B/G protection is like a guard for your network to help ensure compatibility and efficiency. It also reduces interference to your WiFi network in congested 2.4GHz areas.

The purpose of B/G protection is so both newer and older devices on a 2.4 GHz band can work on the same frequency with little to no interruptions. If you live in a location with little 2.4 GHz WiFi use and no wireless G devices nearby, it may not need to be enabled at all.

Here’s how it works:

B/G Protection ‘On’: Priority is given to older devices for connection (although this may slow down the data transmission speeds of other devices on the network and tamper with updated features).

B/G Protection ‘Off’: Data speed is reduced for older devices.

More About B/G

B wireless networking technologies are more dated, and thus they struggle to run on the same network as a more updated G standard.

The WiFi standard G is currently the most common in today’s world. It uses a 2.4 GHz frequency to communicate and transfer data. Furthermore, because it’s significantly more advanced, G is more tolerant to signal interference compared to the older A/B.

Wireless B

The first commercial wireless router that was released was wireless B in 1999. It had an internet speed of 11 Mbps and could support a distance from the router up to 150 feet.

Since Wireless B was released two decades ago, it’s no longer manufactured in the market today.

B/G protection is a feature of outdated routers that modern ones do not have. This serves as a barrier to interference, which is safeguarded by the same internet protocols that are used in every system’s operation.

Wireless G

Wireless G was the second wireless router on the market, and it uses the same frequency (2.4 GHz) as wireless B. However, with increased internet speeds of up to 54 Mbps, it is considerably quicker. Even at a distance of 125 feet, you can still get a stronger WiFi signal than with wireless B.

If you want the latest and greatest router, consider purchasing a wireless N. With internet speeds of over 450 Mbps, it’s the most advanced model on the market for networks that have an abundance of users.

Should You Enable or Disable B/G Protection on Your ASUS Router?

This is the million-dollar question. If you have an older router, should you enable or disable the B/G protection feature?

If you have a more dated router model, I would say yes. The reason is that your device will be able to send information more quickly due to a protected gateway that will be reserved for your router’s signal only. For newer models, it’s likely not necessary (or even an option at all).

When the feature is turned on, it prevents hackers and other detrimental viruses from muddling in your network. Ultimately, the reliability and compatibility of your router’s speed will be more guaranteed.

How do you enable B/G Protection on an ASUS Router?

If you’ve decided that you want your router to have B/G protection, there are steps you can take to ensure the feature is turned on.

It’s important to first note that whether or not this feature can be activated will depend on how old your ASUS router is and the network you’re connected to. Typically, if your router is 5 years or older, the B/G protection feature is available.

To enable B/G protection on your ASUS router, call your network service provider to have them help you address this issue based on your router model.

Typically the options for this include having it ‘Off’ or on ‘Auto.’ Some devices may have a button on the router itself, while others may require you to manage the feature via your account online.

How Do I Make My ASUS Router Signal Stronger?

If you’ve enabled B/G protection on your router and the connection is still weak, there are a few things you can do.

Tips to making your ASUS router signal stronger:

  • Move your router to an unobstructed, elevated location.
  • Consider swapping out the antenna.
  • Add a WiFi booster or extender to your system (these can usually be purchased on Amazon).
  • Swap WiFi frequency bands or channels.
  • Check your outlets and power cords. Sometimes, one or both are failing.
  • Maintain your equipment with regular updates and fresh firmware.
  • Rule out other device interference by creating a distance between appliances like the microwave.

You can go to the ASUS website for any additional information about your router’s particular needs. Here, you can also play with toggling the B/G protection feature.

If all else fails, you may need to upgrade to a newer ASUS router- they only last around 5 years anyways. If you have a rental through your network provider, they can usually send a replacement free of charge!

While ASUS routers are often more expensive than their competitors, they still deliver unrivaled benefits that you won’t find anywhere else.
