Switch to the Least-Congested Wireless Channel: Use a tool like Wi-fi Analyzer for Android or inSSIDer for Windows or Mac to identify the least congested wireless channel for your Wi-Fi network, then change the setting on your router/access point to reduce interference from other wireless networks.If there's a metal file cabinet, microwave oven, or anything else that seems to be obstructing the signal from your router/access point and producing a dead spot, move the obstruction (or your router/access point) and see if that eliminates the dead spot.

Try rearranging your place for ideal signal strength. Identify and Reposition Obstructions: If your Wi-Fi router/access point is sitting next to a metal file cabinet, that's going to reduce your signal strength.Reposition Your Router/Access Point: If your router/access point is in one corner of your building, apartment, or office and there's a dead spot in the opposite corner of your building, try moving the router/access point to a more central location in the middle of your building, apartment, or office.Here are some tips for patching up your Wi-Fi coverage. Now that you've figured out exactly where your wireless dead spots are, you'll probably want to eliminate them. If signal strength drops to zero, you've found a dead spot. Pay attention to the Wi-Fi signal indicator on your device. Just simply pick up your wireless device, connect to your wireless network, and walk around your building, apartment, or office. To be completely honest: You don't really need fancy software to identify dead spots if you don't want to be scientific.

Large metal objects like file cabinets or metal walls may also block Wi-Fi signals. Old buildings may have thick plaster walls that contain chicken wire for support, and this metal wiring can block Wi-Fi signals. Most buildings were built before Wi-Fi was developed, so they may be constructed in ways that interfere with Wi-Fi.

If you have a large building or office and have your wireless router/access point in one corner of the building, there may be a dead spot in the opposite corner of the building where the Wi-Fi signal can't reach. Maybe you're using a smartphone or tablet and walk into a room where there's a dead spot, the Wi-Fi will stop working and you won't receive a signal.Īnything that interferes with Wi-Fi radio waves can produce a dead spot. A dead spot is simply an area within your Building, apartment, office, or any other area that's supposed to be covered by Wi-Fi but it doesn't work there.
