Bringing OpenWrt to the Mikrotik hAP lite (RB941-2nD-TC)

In a previous post I described the Mikrotik hAP lite (RB941-2nD-TC) and its RouterOS and already suggested that I prefer to run OpenWrt on it. Because Mikrotik routers behave a bit different than the usual TP-Link, GL.iNet etc. devices and because there were some pitfalls I had to master myself, here’s some advice to keep… Continue reading Bringing OpenWrt to the Mikrotik hAP lite (RB941-2nD-TC)

In a recent post I mentioned that the Linux kernel has a dedicated API for LEDs. This API is composed of the drivers/leds/ directory and the additional <linux/leds.h> include file, Documentation exists in form of the Documentation/leds-class.txt file.

Netgear-specific information in here, of course.
