I’m using a small, no-name RT5370 from ebay. It’s not fast but it is compatible and reliable, unlike the other three adapters that I have.
Disable interface renaming:
cd /etc/udev/rules.d; ln -sf /dev/null 70-persistent-net.rules
Note that you can’t just delete the file as systemd recreates it.
allow-hotplug wlan0 iface wlan0 inet dhcp pre-up sleep 2 pre-up rfkill unblock all wpa-ssid "your-ssid-here" wpa-psk "your-password-here"
Note that during the boot, systemd seems to randomly set the rfkill bit
which causes dhcpclient to show ‘300 byte’ errors. The
hack works around this. sleep to work around race conditions FTW!
Update the kernel:
cd /opt/scripts/tools git pull apt-cache search linux-image bone ./update_kernel.sh --kernel 4.1.1-bone9

Adafruit 1.8” display
There seems to be probles with SPI on the 4.1 kernel and the 3.14 kernel is missing the cape manager. 3.8 works fine though.
