Place the extender in a location where it can receive a strong signal from the router, but not so close that it causes interference. You can also try changing the WiFi channel on your router or extender to one that’s less congested.
How Do WiFi Extenders Work?
WiFi extenders work by receiving the WiFi signal from your router and rebroadcasting it to extend the coverage area. They usually have two WiFi antennas: one that receives the signal from the router and another that transmits the signal to devices in the extended area. This allows devices that are too far from the router to connect to the network and access the internet. WiFi extenders can be wired or wireless, with wireless extenders being the most common type.
Wireless WiFi extenders are easy to set up and don’t require any cables, making them a convenient solution for extending WiFi coverage. However, they can introduce some latency and may not provide the same level of performance as a wired connection. Wired WiFi extenders, on the other hand, offer a more reliable and faster connection, but they require a cable to be run from the router to the extender.
What Causes WiFi Interference from Extenders?
WiFi interference from extenders can be caused by several factors, including overlapping WiFi channels, physical obstructions, and device conflicts. When the extender is set to the same WiFi channel as the router, it can cause interference and reduce network performance. Physical obstructions like walls, floors, and ceilings can also block or weaken the WiFi signal, leading to interference. Additionally, having multiple devices connected to the network can cause conflicts and reduce network performance.
To minimize WiFi interference, it’s essential to optimize your network configuration and reduce physical obstructions. You can try changing the WiFi channel on your router or extender to one that’s less congested, or use a WiFi analyzer tool to scan for nearby networks and identify the best channel.
