Wireless Access Points: 1xUniFi AC Lite (5 GHz)

The Ubiquity UniFi AC Lite (aka. Salatschüssel) supports both the 2.4 and 5GHz bands as well as 802.11ac. 2.4GHz and 5GHz are currently in use. It’s mounted on a girder, right in the middle of the space, so it provides great coverage. See WLAN Upgrade auf 802.11ac (German) for details.

We’ve deprecated the old TL-WR841Ns because people were complaining about how they are kinda pointless now we have the Salatschüssel.

We build a custom, pre-configured OpenWrt^TM firmware images for all our access points, see its-network-docs/access-points (git repo). There shouldn’t be any need to change settings on the running images, if you want to change something please send a patch.
