Alpha AWUS036H

Created Saturday 25 February 2017

The Alpha AWUS036H, using the RTL8187L chipset, works out the box - but we are gonna tweak it a little for our needs.

Starting the Device

# The device dosen't power up itself once plugged in. Power it up with
# Get the device name with
$ iwconfig
# OR
$ ip link

# In my example the card was named wlp0s20u2
$ ip link set wlp0s20u2 up

Driver

# We'll need a patched version of the driver
$ yaourt -S backports-patches-git

Promiscuous Mode

# To have our monitors catch all packages, we'll need to put it in promiscuous mode
# Create a file in /etc/systemd/system/promiscuous@.service with the following

[Unit]
Description=Set %i interface in promiscuous mode
After=network.target

[Service]
Type=oneshot
ExecStart=/usr/bin/ip link set dev %i promisc on
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

# Then you can Enable/Start Promiscuous Mode for a specific card (Change accordingly)
$ systemctl start promiscuous@wlp0s20u3.service
