  • I did try the wpa-ssid without quotes - no success in connecting to wifi.

    Here is the output of ‘uname -a’:

    root@ubilinux:~# uname -a Linux ubilinux 3.10.17-yocto-standard-r2 #7 SMP PREEMPT Thu Feb 26 09:57:06 UTC 2015 i686 GNU/Linux root@ubilinux:~#

    Here is the output of restarting wlan0:

    root@ubilinux:~# ifup wlan0 Internet Systems Consortium DHCP Client 4.2.2 Copyright 2004-2011 Internet Systems Consortium. All rights reserved. For info, please visit https://www.isc.org/software/dhcp/

  • Yes, definitely running WPA on my network. In your section on enabling WiFi, I reverted back to the quick and dirty way and used the 11 character password, in plain text. I also tried your suggestion to disable IPv6 - all to no avail.

    I’ve reflashed the image 3 times and spent several hours browsing the internet for a solution.

    As I mentioned in my first comment, wifi on the latest Yocto image works very well, so I believe I have the issue narrowed down to Ubilinux.

  • Unable to connect to WiFi network after loading Ubilinux. As a reference, WiFi was working as expected under the Yocto installation. When I run the ifup wlan0 command I get a message stating “No DHCPOFFERS received.”

    Running ifconfig shows wlan0 with no inet addr but it does show an inet 6 address.

    Running iwconfig shows ESSID as “off/any” and Encryption key as “off”

    My interfaces file has the following contents:

    interfaces(5) file used by ifup(8) and ifdown(8)

    auto lo iface lo inet loopback

    auto usb0

    iface usb0 inet static address 192.168.2.XX netmask 255.255.255.0

    auto wlan0 iface wlan0 inet dhcp # For WPA wpa-ssid “A…………Z” wpa-psk c9………..4e10fe05 # For WEP #wireless-essid Emutex #wireless-mode Managed #wireless-key s:password

    And the following 4 lines are for when using hostapd…

    Any help would be greatly appreciated. Thank you.

  • $74.95 seems a bit expensive. I try to support SparkFun whenever I can, and I usually don’t mind spending a small premium on products to support their good work, but Frys has the same product for $59.99 and free, same-day shipping.

  • I guess I’m late to the party. I don’t see how I can acquire this product. Is the offer no longer valid?

No public wish lists :(
