Which of the following is NOT a common cause of slow Wi-Fi?

Router firmware updates are not typically considered a common cause of slow Wi-Fi. While such updates can potentially lead to temporary disruptions or performance changes shortly after installation, they are usually intended to enhance the router’s performance, security, and overall functionality. Thus, if your router is up to date, firmware should not be a factor in consistent slow Wi-Fi speeds.

In contrast, interference from electronic devices, high bandwidth usage, and low signal strength are frequently encountered issues. Electronic devices like microwaves or cordless phones can disrupt Wi-Fi signals, leading to slower connections. High bandwidth usage occurs when multiple devices are streaming, downloading, or using bandwidth-heavy applications, which can saturate the available internet speed, causing slowdowns. Low signal strength often results from distance from the router or physical obstructions like walls, directly impacting Wi-Fi performance. Overall, these factors are much more commonly associated with reduced Wi-Fi speeds compared to firmware updates.
