Interference from Other Devices

As mentioned earlier, 802.11g operates on the 2.4 GHz frequency band. This band is also used by a variety of other devices, including microwaves, cordless phones, Bluetooth devices, and even some older baby monitors. This overcrowding could lead to interference, which would impact the performance and stability of the Wi-Fi connection. The interference could manifest as slow speeds, dropped connections, and an unreliable connection. Users in areas with many other 2.4 GHz devices often experienced these issues, which was a significant drawback.

Security Concerns: Outdated Encryption Protocols

Security is also a big deal. 802.11g used older security protocols, such as WEP (Wired Equivalent Privacy), which are not as secure as newer standards like WPA2 or WPA3. WEP is known to be vulnerable to hacking, making the network susceptible to unauthorized access. This is a very serious concern. If your data is intercepted, it could lead to identity theft, financial loss, and other types of cybercrime. Because of these security vulnerabilities, it's not recommended to rely on 802.11g for modern networking needs, especially when dealing with sensitive data.
