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

#1

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.
