What Is B/g Protection?

B/G protection, also known as backward compatibility protection, is a feature implemented in wireless devices to ensure smooth communication between old and new technology. With the rapid evolution of wireless technology, it is important to maintain compatibility between older devices and new ones. B/G protection helps to ensure that older 802.11b devices can communicate with newer 802.11g devices without causing interference.

The protection scheme works by allowing the router to recognize and support both the older b and newer g (or n) protocols. When a b-capable device connects, the router automatically switches to the b standard. This protects the b device from interference from the faster g/n signals. B/G protection ensures solid connections and maintains network performance for all devices, while providing greater flexibility for users to connect and communicate with each other, regardless of the technology generation.

What is B/G protection?

Background/Group (b/g) protection is a feature that allows wireless devices to communicate with older devices that use the 802.11b standard, while still maintaining compatibility with newer devices that use the 802.11g standard.

– It is a wireless networking feature that ensures compatibility between devices that operate on different wireless standards.
– The b/g protection feature is commonly used in devices that support both 802.11b and 802.11g wireless standards.
– When b/g protection is enabled, a device that supports 802.11g standard automatically adjusts its transmission rate to communicate with an 802.11b device.
– Without b/g protection, communication between an 802.11g device and an 802.11b device can be degraded or completely lost.
– Enabling b/g protection can reduce the overall throughput of a network by slowing down the transmission rate of faster wireless devices.
– In some cases, it may be necessary to disable b/g protection to improve the performance of an 802.11g wireless network.
– Overall, b/g protection is an important feature that can help ensure wireless networking compatibility between older and newer devices.


1. What is b/g protection?

B/G protection is a wireless networking feature that allows devices using the 802.11b wireless standard to communicate with devices using the newer 802.11g standard by slowing down the transmission rate of the latter.

2. Why is b/g protection important?

B/G protection is important to ensure compatibility and connectivity between devices with different wireless standards. Devices using the older 802.11b standard may not be able to connect to a network with only 802.11g devices without b/g protection.

3. How does b/g protection work?

B/G protection works by slowing down the transmission rate of devices using the newer 802.11g standard. This allows devices using the older 802.11b standard to also access the wireless network and communicate with the faster devices using the b/g hybrid mode.

4. Can b/g protection be disabled?

B/G protection can be disabled, but it is not recommended if devices using the older 802.11b standard need to access the wireless network. Disabling b/g protection can also cause interference and slow down the performance of the wireless network.

5. Do all wireless routers support b/g protection?

Not all wireless routers support b/g protection. It is important to check the specifications of the router to ensure that it supports b/g protection if compatibility with devices using the older 802.11b standard is needed.


In conclusion, we have discussed the concept of b/g protection and how it works to ensure that wireless devices can connect to a network seamlessly despite varying standards. This feature is crucial in ensuring that older devices are not left behind as new technology emerges. With b/g protection, networks can accommodate a wide range of devices and maintain reliable connectivity for all users. As technology continues to evolve, b/g protection will remain an important consideration for network administrators and wireless device manufacturers alike.
