I am a tech enthusiast that really enjoys getting into the works when it comes to my setup, but sometimes I take the easy way out.

For instance, I adore my new RTX rig for gaming and content creation, while I still use an old Dell laptop for work.

The variation arises from a sense of security and convenience. But the devices on my home internet do not stop there.

I needed a home network setup that could seamlessly run devices from different generations.

I learned that ASUS routers led the way with backward compatibility that could run slower 802.11b devices on an 802.11g network.

I knew ASUS for their reputation for making futuristic, high-end routers that often seemed overkill for home users.

But their B/G protection setting made all the difference. It seemed delightful at first, but I knew from experience, there had to be a trade-off to backward compatibility. 

I pondered several questions: How does B/G protection affect overall network performance? Is it temporary, and can it be disabled? Does it require firewall disabling?

Browsing through enough blog posts, articles, and forums, I discovered what I needed to know about B/G protection before sealing the deal with an ASUS router.

So I decided to compile it into a comprehensive article, which you can read on to know almost everything you need to know about B/G protection and its features.

ASUS Router B/G protection is a compatibility setting on the router where older devices running on 802.11b wireless protocol could experience a stable connection with a modern router supporting 802.11g protocol.

I’ve also talked about whether B/G protection is good for streaming, and whether or not you should use settings like UPnP and DFS Channels.

What is B/G Protection on Asus Routers?

B/G protection is a compatibility setting available on particular routers that allows stable connection for older Wi-Fi-enabled devices with modern routers. 

Usually, the older devices such as 802.11b client devices operate on outdated networks to connect, 

Hence, modern routers do not support the devices by default.

With B/G protection, devices over five years old can work on newer network routers, such as those supporting 802.11g.

But the setting is not available on every flashy dual-band router you see at Best Buy.

That’s where Asus has the edge over its competitors.

Asus leads the industry in delivering cutting-edge routers with high reliability and additional features that enhance the internet browsing experience.

B/G protection stands out among the arsenal of customizable settings brought to you by Asus routers.

Older Asus routers often used B/G protection to compensate for the lack of uniform protocols that protect a signal from external interference.

So, it offers more efficiency and compatibility around the network.  

Moreover, the functionality of B/G protection is not limited to backward compatibility. 

It is a pretty cool feature that can change your network performance and resolve several device compatibility issues.

So, I recommend you keep reading to learn more about how it works and affects the network.

How to Activate B/G Protection on Asus Routers?

B/G protection is either set to auto or turned off by default in most modern 802.11g routers.

Older routers have an in-built B/G protection option which works as a protective layer to ensure stable connections despite the varying network protocols.

If you want to change the B/G protection setting, you must access the admin router portal at 192.168.0.1 from a web browser.

Benefits of B/G Protection

We have extensively discussed B/G protection on ASUS routers but have not understood its need yet.

Sure, it’s a setting that can turn on to tweak your router, but what impact does it have on performance and security?

Here are some benefits to enabling B/G Protection on your ASUS router –

• Older devices can connect to new Wi-Fi routers uninterrupted
• Cuts down on time taken for AP to transmit on a client network
• B/G protection conceals the router from electromagnetic interference transmitted by other electronic devices using the same wireless internet protocol
• Reduces network theft or unwanted devices as it creates tight-knit compatibility with the router so that only authorized devices can connect to it

So B/G protection can improve your network quality significantly.

Most Wi-Fi or other wireless signals are transmitted at a 2.4GHz frequency range, so the setting can reduce interference if your router is placed in a cramped area.

Disadvantages of B/G Protection

Sure, B/G protection allows seamless connection between older devices and ASUS routers.

But it comes at a cost.

Despite its benefits in terms of compatibility and reliable connections, you will not experience the same internet experience with active B/G protection.

Here are the few disadvantages of B/G protection –

• It reduces the overall output speed of your connection
• It disables some of the latest features on advanced routers, arising from network throttling

I’d recommend enabling B/G protection only when connecting an older device to your router.

Otherwise, you will not experience the optimum network experience on new devices, leaving performance on the table.

How will B/G Protection Affect Internet Speed?

B/G protection negatively impacts your overall internet speed from your router.

Hence, I always keep it turned off or set to auto so that only when I have an older device can I run it.

We can better understand the impact of B/G protection by touching upon two wireless network protocols – 802.11b and 802.11g.

Older devices use the 802.11b protocol, which slows down modern 802.11g compliant routers as it uses the same or nearby channels.

B/G protection is all about compatibility, so even though your old device will experience a stable internet connection, you’ll find that you’re not getting full internet speed through your router.

So if you value your network performance, it is best to use B/G protection only when a device warrants its need.

Is B/G Protection Good for Gaming?

The straightforward answer is negative.

B/G protection is not recommended for gaming.

It brings down the down speed for your network, and you are likely to experience ping spikes and latency.

So if you are Warzone on B/G protection, don’t be surprised if your clear headshot did not register.

Moreover, B/G protection also limits the capabilities of a gaming router by disabling particular features that improve your network performance in-game.

However, if you are a casual gamer looking to connect your old laptop to play some Quake, you will require B/G protection for a reliable connection.

While it compromises the performance, you will at least have a stable Wi-Fi connection.

Is B/G Protection Good for Streaming?

Like gaming, streaming requires a decent-performing network to push transcoded audio-visual data from your PC or laptop to the Twitch servers.

While streaming itself is a CPU-intensive task, you need a reasonably high speed to stream in FHD.

B/G protection should be exclusive to older devices that otherwise experience connection issues with the router.

So unless your streaming setup comprises an initial B/G era device from over five years ago, I advise you to keep B/G protection off or set to auto.

While it does protect your network from interference and stabilizes it, the trade-off for speed may not offer an entertaining stream experience for your audience.

Does B/G Protection Affect NAT Type?

NAT, or Network Address Transmission, is a networking process where local IP addresses are translated to one or more global IP addresses.

It provides internet access to local hosts and interacts with the firewall and router.

NAT offers extra protection for your network by hiding it from unknown devices and authenticating incoming packets of information.

NAT type is a specific setting that determines how you are connected to the local network.

Whether you are connected directly to the internet or through a router with limited functionality – the NAT type decides the nature of the connection.

With active B/G protection, you may experience network throttling and a hindered internet experience. 

Hence, considering using standard IPv4 routing by disabling NAT –

1. Open 192.168.0.1 in your browser URL bar to configure the ASUS router from the admin portal
2. Navigate to Networking, then Local Networks, and finally, Local IP Networks
3. Select the IP network where you want to disable NAT
4. Click on “Edit”
5. Select IPv4 Settings
6. Change the IPv4 Routing Mode to “Standard.”
7. Save the changes

Should you use UPnP?

UPnP refers to Universal Plug-and-Play – a network protocol that allows you to quickly connect devices to a network without any manual configuration.

So if you are a gamer or use peer-to-peer applications and VoIP which require port forwarding, it is best to use UPnP for a seamless experience.

UPnP automatically allows compliant devices to set their port forwarding rules.

Hence, with UPnP, all local programs are trustworthy, which could pose a security threat.

It means malicious programs can manipulate the ports, and hackers can tap into your network.

Disabling UPnP is a trade-off between convenience and security.

If you are not a heavy driver of peer-to-peer apps, you can disable it.

The router will now shut down your LAN ports for automatic connection and reject all incoming requests, including the legitimate ones.

You will need to manually set up a device each time you want to connect a new one.

Is Using DFS Channels a Good Idea?

DFS, or Dynamic Frequency Selection, increases the number of Wi-Fi channels you can use.

That’s a mouthful of words, but do more available channels make a difference for you?

Wi-Fi channels are sub-channels within a frequency band, such as 2.4GHz and 5GHz, to transmit and receive data.

DFS extends the number of available 5GHz channels by using 5GHz Wi-Fi frequencies reserved for satellite communication and military radar.

Usually, the standard consumer does not use a DFS channel, so these don’t have a lot of traffic.

DFS channels offer a better network performance with far lesser electromagnetic signal interference.

Hence, DFS channels are strongly recommended for users living in crowded neighborhoods or apartments, away from a radar installation.

However, on the flip side, using the DFS channels legally requires a Channel Availability Check, which could take up to 10 minutes.

Your router will seize connection with any non-DFS channel while it searches and verifies the preparedness of a DFS channel.

So you will go offline temporarily unless you activate auto-DFS channel selection.

Final Thoughts on B/G Protection

The final question as to whether you require B/G protection or not relies on your nature of usage.

B/G protection ensures that both 802.11b and 802.11g radio signals can co-exist in the same space.

It does not disable your firewall and ensures a secure connection for older devices at the cost of some performance.

Frequently Asked Questions

Which is better, 802.11 b or g?

802.11g has advantages over 802.11b. It combines features from both 802.11a and 802.11b to deliver bandwidth up to 54 Mbps and uses 2.4GHz to cover more network area. Moreover, 802.11g access points are backward compatible with 802.11b.

Should I turn off 802.11b?

Stats indicate a significant network performance loss when 802.11g routers are compelled to connect with older 802.11b devices.

Therefore, while you may have backward compatibility active on your router for connection convenience, it is only recommended when you need to use older devices.
