![]() With the Pi 4 housed in each enclosure, connected via both WiFi and Ethernet. I’d like to replace this with some Ubiquiti PoE access points at some point in the future, but that’s for another day.Įach Pi test configuration was positioned in the same place, tests were then conducted as close together as practically possible to avoid influence from atmospherics and other external sources Testing method This setup came to be after eventually deciding to standardise on one manufacturer to aid with device roaming between AP. 2 x Apple AirPort Express (802.11n 2nd generation), 1 x Apple AirPort Extreme (802.11n 5th generation) and 1 x Apple AirPort Extreme (802.11ac). ![]() My home is probably an atypical setup, with the home WiFi coverage provided by 4 dual (2.4Ghz & 5Ghz) access points. I’d wanted to follow on from my post looking at the impact on cooling from different cases by examining their impact on WiFi signal strength.īluetooth testing is out of scope. Whilst I only have a small number of different cases to test with. The option number, 3 and 4 are only displayed when the wireless controller supports noise level information.Note: You may want to check out a more recent article I wrote on WiFi performance: Raspberry Pi WiFi Performance Revisited (Feb 2021)įollowing a comment from Geir on a previous blog post, where he asked if the metal enclosures which may help assist in cooling the hot Pi 4, could impact WiFi signal strength. In the Levels section, you can see up to four bar charts that show: To do this, select a parameter with and then change the value with e. ![]() This allows you to change all the program options, such as level and interface scale parameters, and save the new settings in the configuration file. Station-specific information includes station type (ESS for access point, IBSS for Ad-Hoc network), station count, and channel usage. The colorless information that follows the MAC address lists relative and absolute signal strengths, channel, frequency, and station-specific information. It is classified according to the sort_order.Įach entry begins with the ESSID, followed by the color-coded MAC address and signal / channel information.Ī green / red MAC address indicates an access point (not) encrypted, the color changes to yellow for non-access points (in this case, the mode is shown at the end of the line). When executing this command, a list will appear which is the following:Ī regularly updated network scan, showing access points and other wireless clients. Sudo apt-get install wavemon Using WavemonĪs said before, Wavemon is a tool that we are going to use via the terminal, so we are going to use everything on the command line.Īll you need to do is run the following command and follow the instructions according to the shortcuts and what you want to check on your WiFi. Once the terminal is open, we are going to type the following commands: sudo apt-get update Now we are going to do the Wavemon installation, to install this utility we must open a terminalYou can do it manually or if you prefer you can use the keyboard shortcut Ctrl + Alt + T. ![]() How to install Wavemon on Ubuntu and derivatives? But in particular I prefer to use the keys that go from F1 to F10, it is much more practical. For example, the "info" screen shows current levels as bar graphs, while the "level" screen represents the same levels in a moving histogram.Īt startup, you will be able to see (depending on the configuration) one of the different monitor screens.Īt the bottom, you will find a menu bar that shows the screens and activation keys.Įach screen is activated by the corresponding function key or by the key corresponding to the first character of the screen name. The wavemon interface it is divided into different 'screens'.Įach screen displays information in a specific way. Record levels in real time, in addition to displaying information about wireless and network-related devices.
