Your home may have everyday items that surprisingly interfere with your WiFi signal-from electronics to structural features, these culprits can cause slowdowns and dead zones. Understanding their impact can help you optimize your network.
Microwave ovens are one of the biggest sources of WiFi interference, as they emit signals in or around the 2.4 GHz spectrum-the same band used by many routers. When on, a microwave can greatly hinder WiFi performance, especially if your router is close by. Keep your router away from the kitchen or switch to the 5 GHz band.
Other older versions of cordless phones, especially, operate within the same 2.4 GHz frequency. This congestion interferes with WiFi. Replacing them with DECT 6.0 phones that run on a different frequency solves the problem. Baby monitors commonly use 2.4 GHz to communicate and become the unexpected disruptor. Seek versions with different frequencies or newer models that are WiFi friendly.
Devices like Bluetooth speakers and headphones operate on the same 2.4 GHz band as WiFi, causing interference when Bluetooth devices are used along with WiFi. The router settings can be changed to mitigate Bluetooth interference or reduce the number of Bluetooth devices. Other smart home devices, such as plugs, bulbs, and cameras, are also overloading the 2.4 GHz spectrum. This can be helped by using dual-band devices or relegating these gadgets to a separate network.
Other physical features in your house may also impact WiFi signals, including fish tanks, mirrors, and thick walls. Aquariums absorb the signal, while mirrors scatter it, weakening your connection. WiFi, on the other hand, is blocked by concrete or brick. Locate your router higher and centrally with minimal or no interference from the aforementioned objects.
Refrigerators and metallic surfaces are added appliances that further reduce WiFi by creating dead zones because of the blockage of signals. Wireless security cameras, which work on similar frequencies, can also contribute to interference. Using wired options or assigning cameras to a separate network helps reduce this impact. Even fluorescent lights and festive Christmas lights can disrupt your network by emitting electromagnetic interference. Replacing fluorescent lights with LEDs or relocating your router away from holiday decorations can also help.
External factors like your neighbors’ routers may also cause problems. Overlapping WiFi channels can congest the airwaves, especially in apartment complexes. Using a WiFi channel scanner to identify and select less crowded channels can make a noticeable difference.
Lastly, outdated routers lack the capacity to handle modern demands and may struggle with interference. Upgrading to a dual-band or WiFi 6 router ensures better connectivity and faster speeds.
