When a WiFi extender receives a weakened signal, it can struggle to rebroadcast a strong, reliable signal, leading to lag and other performance issues.
Interference from Other Devices
Another reason WiFi extenders can cause lag is due to interference from other devices. WiFi extenders operate on the same frequency band as your router, which means they can be susceptible to interference from other devices that use the same band, such as cordless phones, microwaves, and neighboring WiFi networks. This interference can cause lag, dropped connections, and other performance issues.
Network Congestion
Network congestion is another common issue that can cause lag when using a WiFi extender. When multiple devices are connected to your network, they can compete for bandwidth, leading to congestion and lag. WiFi extenders can exacerbate this issue by introducing additional latency and reducing the overall bandwidth available to each device.
Latency
Latency is a critical factor in network performance, and WiFi extenders can introduce additional latency into your network. Latency refers to the time it takes for data to travel from your device to the WiFi extender and then to the router. This latency can cause lag, particularly in applications that require real-time communication, such as online gaming and video conferencing.
