Which two devices are known to commonly affect wireless networks?

The correct answer highlights the impact of cordless phones and microwaves on wireless networks, particularly those operating in the 2.4 GHz frequency range, which is commonly used for Wi-Fi.

Cordless phones, especially older models, typically operate on the 2.4 GHz frequency as well and can emit signals that interfere with Wi-Fi communications. This interference can lead to dropped connections, slower network speeds, or degraded performance for devices that rely on the wireless network.

Microwaves also emit electromagnetic waves in the 2.4 GHz range when they are in operation. When a microwave is heating food, it can cause significant interference in nearby wireless devices, disrupting signal integrity and leading to similar issues as those caused by cordless phones.

These two devices are particularly problematic because their operation can easily coincide with the usage of wireless networks in homes, thus creating an environment where connectivity issues are more likely to occur. Understanding the impact of such devices on wireless networks is critical for troubleshooting and maintaining optimal performance in a wireless environment.
