Are you looking into turning your Raspberry Pi into a Wireless router? Then I’ve created a tiny Arch Linux ARMcreate_ap (by oblique) based setup, packaged into a downloadable image that may interest you. Once booted the access point will create SSID ArchWiPI  via network address translation (NAT). UPDATE: Today I received my LB-Link long Range WiFi USB Antenna which replaced my Edimax EW-7811Un If you prefer mini dongles the best I’ve tested so far is TP-LINK TL-WN725N Wireless N Nano USB Adapter. These were manufactured for two very different purposes, I still love both. The LB-Link has more than double the range while the Edimax is about the length of a finger tip! But for the this project of turning the Raspberry Pi into a wireless router the LB-Link is a must have! Here are some comparisons of signal strength from about 20 feet away in another room. The LB-Link is on the left and Edimax on the right….

Arch-WiPi usb dongle signal strenght comparison

Arch Linux Raspberry Pi WiFi AP Requirements

  • Raspberry Pi Model B Revision 2.0
  • Power adapter with at least 1500 mA (2 amp recommended)
  • Minimum 2GB SD Card Fat32 formatted
  • Wifi USB dongle running rtl871xdrv. Eg. Edimax EW-7811Un. (I recommend this or this)
  • Network Cable with Internet access. (eg. Internet cable from your cable modem)

Image Installation and Access Point Setup

  • Download my Arch Linux Wireless Raspberry Pi image: archwipi.img.tar.gz (252MB)
  • Extract it. eg:  sudo tar zxf archwipi.img.tar.gz
  • Write the extracted image to your SD card. eg: sudo dd if=archwipi.img of=/dev/sdb …change sdb if necessary. Don’t run this command if unsure!!!
  • Optional – extend partition to use all of disk. You can use gparted.
  • Plug your internet cable and new Arch WiPi SD card into your Raspberry and power it on.
  • Everything is automated so after a minute or so scan for a new network SSID = archwipi
  • If you don’t see the archwipi SSID, then it means you need to manually install your WiFI dongle drivers.
  • The wifi password password is: 1010101010
  • If you need to login to the Pi the credentials are: root | archwipi
  • You can change the WiFi password to what ever you like by editing: /usr/lib/systemd/system/create_ap.service
  • Check CPU speed, temperature and more using ./bcmstat.sh
  • You can also view graphs of Pi stats, browse to this address 192.168.12.1:8080/archwipi (powered by Monitorix)

Example from the built in stats page (I was still tweaking and rebooting as well as swapping SD’s to compare different settings which the graphs reflect).

Arch WiPi Stats

Note: There’s absolutely no over volting. However, the image comes with with modest over clocking to 800Mhz. I have plans for “under volting” in future updates which will help keep the Pi’s temperatures even cooler 24/7. However, with current settings the Pi’s arm will drop right down to 200Mhz when idle. Here’s speedtest.net results from my Laptop via Raspberry Pi WiFi router which is connected to ISP cable modem (pay for 25Mb/s plan):

Please let me know if you do try this. Your feedback will help ensure that this works plug-and-play for everyone.

  2. hello,
    thank you for your great work. I can not install the driver for the TP LINK TL-WN725N wifi adapter. Could you integrate? thank you

  3. Hi James

    Super image !! Just what i need.
    Thank you

  4. I’m happy this is useful. Let me know if you find any issues or have any suggestions. I will be updating it shortly.

  5. Well done! Works out of the box! Will be my router for travelling now :)

  7. Hi Hayden,
    thank you very much for your work. Nice and slick little image you got there.
    Well, I’ve tried to get another Wifi-Adapter to work (since I’ve got several laying around) and ran into a little issue. The root-partition seems to be a little bit too little to install new drivers – (in my case it’s the rtl8188 – driver here in AUR: https://aur.archlinux.org/packages/dkms-8188eu/)
    Pacman drops out at #pacman -Syy dkms-8188eu

    Repartitioning doesn’t help since Arch is using the free space for /home/ and not for system /.
    I don’t know what your plans are – but holding a few drivers for common wifi-adapters (ath9k ?!) in the system would give the image a nice push ;D

    Thanks again, have a good one

  8. Hi Hayden,
    Great work! Long range LB-Link does not work on default Raspbian or ArchLinux, yours image is the only one working for LB-link as I know.
    Can you give us detail description on how did you build the image?
    Thanks in advance.

  9. Thanks for confirming that it works. Much appreciated. If users find this useful I can keep it up to date. The image is for those who don’t want to spend the time building one.

  10. Great image! How can I install Samba to make it a NAS?
    apt-get install samba samba-common-bin does not work.

  11. This image is based on Arch Linux which does not use the apt-get package manager like Ubuntu/Debian does. Instead it uses pacman (https://wiki.archlinux.org/index.php/pacman). So should be able to install using: sudo pacman -S samba for more see: https://wiki.archlinux.org/index.php/Samba

  12. Hi Hayden James,

    Thanks for the great tutorial and image..

    How about if i want to connect to the internet via wireless 3G/GPRS rather than the Ethernet cable, how do i go about this? is there a a simple cheap Rpi 3g shield or dongle out there and how can I modify your image accordingly?

    Thanks

  13. You’ll need something like this:

    I’ve not attempted this yet sorry.

  14. Hi Hayden,

    Arch is a great distro and what you’ve done with it is great! Because of this I bought the LB-Link, since it works and the range is remarkable. But is there a way to hide the access point? I’ve edited /usr/lib/systemd/system/create_ap.service:
    ExecStart=/usr/bin/bash create_ap wlan0 eth0 [AP] [pass]

    No dice, and changing HIDDEN=1 in /usr/bin/create_ap doesn’t do the trick as well.

    Is this card not capable of hiding it’s SSID? Or am I looking in the wrong places?

    Thanks!
