Software Access Point

Just your basic bridge and hostapd setup. I am doing this with a raspberry pie and a alpha AWUSO36NH. One of the biggest issues is understanding the new systemctl methods of archlinux.

hostapd

Concern rests with the file (Most of these are default):

/etc/hostapd/hostapd.conf

Notes

systemctl and the /etc/conf.d dir? I edited dhcpcd and added -t 30
