Alternative router firmware: OpenWrt and no longer DD-WRT

Diese Seite gibt es auch in Deutsch

Router manufacturers usually provide updates for their products only for a limited period of time, often leaving security holes on older devices unpatched. One possibility to provide the hardware with an up-to-date operating system (OS) again is offered by the freely available router firmware: OpenWRT. In addition, OpenWRT can extend the functionality of the router with additional services, such as VPN, additional statistics, or when using multiple devices, with WiFi roaming, see also: Set up network for home: Expand and improve your LAN / WiFi.


OpenWrt is not only the oldest open source router project, it is still actively developed and maintained today. OpenWrt offers for devices of different manufacturers beside regular current updates also innumerable extensions.

DD-WRT was the first choice as an alternative router firmware for a long time and still offers firmware images for a variety of different devices. In recent years, however, development has stalled somewhat, and only beta versions have been updated since 2008. DD-WRT offers an alternative especially for routers with Broadcom chips, since DD-WRT has permission to use proprietary, closed-source wireless drivers from Broadcom. OpenWrt, on the other hand, uses only free and open source drivers (FOSS), see:

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.
