In 2023 we will also have a backup wifi/router in Austria, a £20 TL-WR841N belonging to Wookey which is configured identically to the Netgear device except that the username is 'root' not 'admin'. It would be good to test this so we could give ARM their WNDR4000 back, and the TP-link router can become expo's.

One important difference is that the ethernet cable from the netbook is plugged into the blue socket on the WR841N (it is yellow on the Netgear), and the 4 white sockets on the Netgear are 4 yellow sockets on the WR841N. A word of warning: the WR841N has been flashed with new firmware (openWRT) and so any documentation you may read in online manuals for it will be wrong: notably the reset and wifi on/off buttons don't have any effect, and the lights don't flash in the way the manuals say they do. There is also no USB socket, no 5Ghz, slower ethernet (100Mbps not 1Gbps) and the wifi range out to the tents is probably worse than the Netgear wifi. - + +

Alfa wifi device

+

The Alfa AWUS036ACH is a high-power external wifi aerial to connect across the campsite to the gasthof. It uses the Realtek RTL8812AU chipset. Annoyingly this does not have a mainline kernel driver so we have to use a dkms driver '8812au'. This is not properly debianized so if you upgrade the kernel on the aspire it has to be rebuilt. The source and the rebuild scripts are in /home/expo/alfa-driver/morrownr. installing the kernel headers for the runing kernel, then running /home/expo/alfa-driver/morrownr/install-driver.sh NoPrompt will update it. +

I recommend not updating the kernel for the duration of expo. +

IP6

While you can use 5Ghz wifi and IP6 to connect within the hut, there is no IP6 connectivity to the external internet. Sorry. We are dependent on the Gasthof system for this. Use a phone and data roaming if you want it.
