Tutorial - Loading Debian (Ubilinux) on the Edison
about 3 years ago
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
Here is the output of restarting wlan0:
root@ubilinux:~# ifup wlan0

No DHCPOFFERS received.
No working leases in persistent database - sleeping.
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:
iface lo inet loopback
iface usb0 inet static
iface wlan0 inet dhcp
# For WPA
# For WEP
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 Is the offer no longer valid?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 :(
