 This HOWTO shows you how to replace the WiFi element of your home network setup with a Raspberry Pi running Slackware.  Other HOWTOs explain how to setup DHCP and so on for your wireless devices, but this tries to keep things really simple and just give you an ethernet->Wifi bridge.  This is very close to the config I ended up with when I configured a TP-LINK ADSL router to do the same thing, only this way I get to patch stuff a lot more easily. This HOWTO shows you how to replace the WiFi element of your home network setup with a Raspberry Pi running Slackware.  Other HOWTOs explain how to setup DHCP and so on for your wireless devices, but this tries to keep things really simple and just give you an ethernet->Wifi bridge.  This is very close to the config I ended up with when I configured a TP-LINK ADSL router to do the same thing, only this way I get to patch stuff a lot more easily.
  
 +Although I've originally written this HOWTO for a RPi 3, I've since tried it on an RPi2 and it works just as well.  Interface wlan1 will obviously change to wlan0 because the Pi2 has no on-board WiFi however.

 +===== QR Codes =====

 +
 +No home WiFi network setup is complete without a QR code that you can wave at all your mates when they are round your house wanting to connect.  You can create one of these from your WiFi settings using the **qrencode** program, available from [[https://slackbuilds.org/repository/14.2/graphics/qrencode/|Slackbuilds]], or alternatively, get the build from [[http://www.slackware.com/~alien/slackbuilds/qrencode/build/|Alien Bob]] for a slightly later version.
 +
 +Type the following to create a PNG file with the code, which you can print, copy to your mobile, put on a local webpage or whatever.
 +
 +<code># qrencode -t PNG -o wifi-setup.png "WIFI:S:MYSSID;T:WPA2;P:MYPASSWD;H:true;"</code>
 +
 +The above assumes WPA2, MYSSID should be replaced with your SSID, MYPASSWD replaced with your password.  For my Android phone I installed a piece of software from the Play store called [[https://play.google.com/store/apps/details?id=com.google.zxing.client.android|Barcode Scanner]] by the [[https://play.google.com/store/apps/developer?id=ZXing+Team|ZXing Team]].  It works very well for reading these codes.
 +
 +At a pinch, the following bash script should pull your SSID and passphrase out of the hostapd.conf file, and automatically use them to create a new QR code, so you can quickly keep it up to date after any changes.
 +
 +<code>#!/bin/sh
 +
 +SSID=$(cat /etc/hostapd/hostapd.conf | grep ^ssid= | cut -d= -f2)
 +PASS=$(cat /etc/hostapd/hostapd.conf | grep ^wpa_passphrase= | cut -d= -f2)
 +
 +qrencode -t PNG -o hostapd.png "WIFI:S:$SSID;T:WPA2;P:$PASS;H:true;"</code>
