Show WLAN users: connected devices

Diese Seite gibt es auch in Deutsch

To find out which devices are currently connected to your WLAN, they can be displayed via the router or a network scan.

Via the router

The connection from the home network to the Internet usually takes place via a router of the Internet provider. Of course, it is possible to display all connected devices via the router: The routers have a small web server for the administration, whichcan be called via thebrowser.

On a Windows device, the easiest way to find out the address for managing the router is to use the ipconfig command. To do this, enter the command "ipconfig"in the command prompt:

The default gateway is usually the address of the router and can be accessed in the browser:

Some routers display information about the network without a username and password. If the router requires login information to display it, it can be found either on the back of the router or in the provider's documents.

Depending on the router model, there are different menu items for the overview of the network: Network, LAN, WLAN, Status, or possibly also under DHCP Leases.

If you own a router with OpenWrt, you will find an overview of the connected devices after login, directly on the start page:

Active DHCP Leases, i.e. devices that have been assigned an address by the router:

and devices that are connected to the WLAN under "Associated Stations":

Network scan

Android

If the smartphone is in the WLAN, the network scan can also be done with a corresponding app.

As an example I tested the app "Network Analyzer":

Windows

If you don't have access to the router, you can scan the network for active devices. The easiest way to do this in Windows without tools is via PowerShell:

Ping with Port | cmd vs. PowerShell: Test-Netconnection
As is well known, the tool ping can be used to test the access to a certain network device and its response time. Not all devices will respond to a ping, but they may respond to a particular Tcp-Port if a particular network service is provided through it. Windows PowerShell allows you to test a specific port using Windows board tools. The psping tool can also measure the response time to a specific port.

OpenWRT hardware recommendation - available devices 2022
OpenWRT provides a uniform and up-to-date software for different network devices like routers or access points and delivers countless additional setting options, software packages and functions. This makes it possible to combine new and old devices from different manufacturers and, among other things, to use low-cost hardware in a common WiFi, see: Setting up a home network: Extending LAN and WLAN | Improving.

Find IP addresses in the network even if their firewall is enabled
If you want to get a quick overview of all active devices in a network, you can do this with network discovery, commands in the command prompt, in PowerShell or with special IP scanners. The PowerShell commands presented at the beginning of this post give a quick overview of all devices on the local network and may make special programs for scanning the network unnecessary.
