If your home’s Wi-Fi is slower than expected, it could be caused by Wi-Fi interference. Here are the most common sources:
1. WALLS AND FLOORS BLOCKING WIRELESS SIGNALS – Denser materials such as concrete, brick, and metal can make it difficult to connect. These materials can also slow your network speed or even completely block wireless signals from reaching certain parts of your home. Large furniture items such as filing cabinets or bookshelves, as well as appliances like stoves or refrigerators, can also interfere with Wi-Fi. You may be able to solve the problem simply by moving your router to a different location.
2. APPLIANCES AND ELECTRONICS EMITTING RADIO FREQUENCY INTERFERENCE – Wi-Fi interference can also come from other electronics and appliances that aren’t connected to your wireless network but use the same 2.4GHz or 5GHz frequencies to communicate. Examples include cordless phones, Bluetooth devices, and baby monitors. Microwave ovens generate radio frequency noise as a byproduct, so if yours is located close to your Wi-Fi router, you may notice a network slowdown or get disconnected only when you’re using your microwave. Again, try relocating your router.
3. OTHER WI-FI NETWORKS USING THE SAME CHANNEL AS YOUR OWN WI-FI NETWORK -Interference from competing Wi-Fi networks is especially common in apartment buildings and other densely populated areas. Wi-Fi networks broadcast on channels, so when nearby Wi-Fi networks are set to use the same channel, they’ll constantly be competing with each other for limited bandwidth. To rectify this situation, see if your router is able to automatically find the least crowded Wi-Fi channel. If not, you may want to upgrade to a new router with this feature.
