Inssider signal2/25/2024 Furthermore, using a plot, inSSIDer will allow you to monitor the quality of the signal as a control. That article covers the subject much better than I can in this answer, so if my answer disagrees with the article, I would urge you to trust the article before my word. Specifically, inSSIDer can detect any wireless networks that offers coverage in your area and will list all the details in the main user interface: SSID, MAC address, channel, RSSI, security and network type, speed and intensity of the signal. This seminal work from TomsHardware provides an enormous amount of insight into the physical characteristics of WiFi and why most implementations of it are terrible. Simply changing it from one angle to another can completely change its wireless reception characteristics. Since you said "laptop", I surmise that you probably change its orientation and position quite frequently. Even if you have no sources of interference, simply rotating a device, such as a laptop or the wireless router, may destabilize the signal strength. WiFi, operating in a high radio frequency spectrum, is also very sensitive to orientation, direction, and polarization. You'll then also need to detect any sources of internal interference inside of the rooms themselves, which may be affecting the signal. One of the coolest new features is the rapid Signal Strength updates that we are able to retrieve for APs AND clients. If you want to avoid sources of interference, you will need to construct a Faraday cage around the room(s) that you want to isolate from external interference. Other WiFi users or misbehaving WiFi devices.
