For some reason, my Manjaro ARM install on the Raspberry Pi 4 is missing my 5GHz WiFi. It can scan some 5GHz networks, but not my home network. This never happened before on my Arch Linux install, and is very weird. I am aware that this is probably due to wireless country code being set up incorrectly.
Update Mar 23 ‘21: Improve the stability of IPv6 tunnel. I like IPv6, but Cox’s IPv6 network is suboptimal. I like the idea of a VPN providing millions of IPv6 addresses to its clients. Wireguard, it seems, is the obvious choice for creating an IPv6 VPN. Yes, I did set up Wireguard servers before using Debian, /etc/network/interfaces and wg-quick.
So I was testing some code on my loyal Raspberry Pi 4, ver. 1.2. The Pi is directly connected to my router in another room. Cuz, like, Pi’s ethernet is so much more stable than its wireless. The downside is that every time the Pi had an issue, I had to run over to the other room to recover it.
