Hi Pete,
Pete wrotei have an Edimax USB WiFi dongle which is an AC high gain antenna (EW-7811UAC) but this is not working with this distro (it worked fine with an XBMC distro). if i plug it into the USB port on the Pi no blue light on the edimax and it kills the ethernet connection. Can I gt this dongle to work somehow?
You should first try this command from SSH and then reboot and retest, its possible that the driver has been added:
pacman -Sy linux-firmware
If this has no effect, look at this post:
#13123 I have a feeling it is the correct driver. Follow the instructions up to and including the
depmod command, the rest should not be required. You need to copy it to '/usr/lib/modules/
<your linux version>-ARCH/kernel/drivers/net/wireless'. Look in the directory /usr/lib/modules to determine the linux version.
If it still wont work you will need to download the driver '8812au-4.1.13-v7-826.tar.gz' from the internet (for example here:
http://downloads.fars-robotics.net/wifi-drivers/8812au-drivers/) and work out how to install it. There are lots of instructions pages on internet explaining how to do this.
