USB WiFi Adapter

Here’s a link to the USB WiFi adapter I used while testing HSMM-Pi.  The adapter uses the Ralink 5370 chipset and is supported out-of-the-box on the Raspbian Wheezy 2013-05-25 release.  I plan on testing it with a high-gain directional antenna soon, and will post a follow-up with my findings.

  1. Thanks for the posts! I’ve ordered the same chipset based usb stick on ebay for $5.
    Will see if it’s compatible with RPi.

    Some good and simple designs of homebrew high-gain wifi antennas (omni and directional) can be found here: http://pe2er.nl/

  2. Thanks VA3PAW, please let me know how your installation goes. I also appreciate the link to the antenna designs. I noticed that you forked the project on GitHub; I’m looking forward to any additions or fixes you might have!

    • Hello Eric,

      Here are some recommendations for troubleshooting USB WiFi:

      1) Login to the Raspberry Pi, either through SSH or a console session. Next, run the following command:
      ifconfig -a

      That will list all of the network interfaces, their device names, and IPs. You should see the WiFi adapter listed as wlan0. If the device has a different name, then configure HSMM-Pi with that device name through the web interface.

      2) Get a listing of the USB devices on the Pi by running lsusb. Example:

      pi@raspberrypi ~ $ lsusb
      Bus 001 Device 002: ID 0424:9512 Standard Microsystems Corp.
      Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
      Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp.
      Bus 001 Device 004: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter
      Bus 001 Device 005: ID 0d8c:0008 C-Media Electronics, Inc.

      In this case, the RTL8188CUS device is the USB WiFi adapter.

      3) Do some web searches for the USB WiFi adapter. What is the manufacturer/model? Are there Linux drivers available for the model and its chipset? You might need to download and compile drivers from the manufacturer in order for the adapter to work.

      I hope this helps, 73,

  4. Thanks Eric. It sounds like your WiFi adapter has the chipset (Ralink 5370) as the adapter I tested with. Did you specify ‘wlan0’ as the WiFi device name in the HSMM-Pi Web UI? Also, are you using the July 2013 distribution of the Raspbian Wheezy image?

  5. hi Scott
    you had reason i used an old raspbian distribution. Morning just put latest distribution and all seems ok. Better i received one raspi ordering last week and installed the program…But always no lucky hi i have now 2 rpi and one wrt54 and nobody see other !…but the usb dongle run , i can update raspian distribution and second no…I think it would be cool to have screen copy for cfg 2 pi both .these screen copy could be help some oms.

  6. Hi Eric, it sounds like upgrading to the July 2013 distribution of Raspbian Wheezy made the difference. Feel free to leave another comment if you encounter additional issues.

    Best,
