Re: [Gumstix-users] connecting to wifi

[Chris C. <chr...@gm...>]

vikrant,

It sounds like you are using an SD card or Image that has been booted
before on a different gumstix. For example, if you write a freshly made
image to an SD card and boot it, you will see wlan0. If you then pull that
SD out and boot it on a different gumstix, you will see wlan1 and so on.
This happens because the interface name "wlan0" is being associated with a
physical wireless chip using its unique identifier or UID, which is saved
in "/etc/udev/rules.d/70-persistent-net.rules". Now, if you want to set the
name of your wireless interface back to wlan0, just run "rm
/etc/udev/rules.d/70-persistent-net.rules" then reboot and you will see
that your wireless interface is now wlan0.
