You can walk around in your house with this tool to locate the interference and detect wireless channel that is full of noise. This tool will make your notebook as a simple spectrum analyzer. If you want to know how it happens, have a look on Wispy from Metageek. This is because it will create interference and affect the wireless signal strength. If the signal is not good, reposition it again and test the signal strength again.ĭon’t place your wireless device near to cordless phones, microwave ovens, bluetooth cell phone and other devices that using 2.4 GHz radio frequency if possible. After repositioning the device, you should check the signal strength by connecting to it. I usually place my access point as high as possible, so that can reduce the signal blocking. Usually the effective wireless range would be 100 feet (30 meters), however be aware that each wall and ceiling could reduce the coverage from 3-90 feet (1-30 meters) or total blocking depending on the thickness. You should reposition wireless router or access point at a clearer area and minimize the blocking from thick wall and other obstacles. So, here are some tips you can use to resolve coverage problem in your wireless network: Exceed the effective coverage range of wireless router and access point (AP) Wireless signal is blocked by thick wall, metal door, ceiling and other obstacles Interference by other electronic devices that using 2.4 GHz radio frequency The problems might be caused by following factors:
