Public bug reported:
wifi card with beaglebone black on ubuntu is working good. But on next
boot after an abnormal shutdown I can not connect to wifi. I have to run
iwconfig and find out wlan interface and update the
/etc/network/interfaces with appropriate wlan interface - mostly wlan0
becomes wlan1 becomes wlan2 .... -. Here is my iwconfig
$ iwconfig
wlan3 IEEE 802.11bg ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=0 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Power Management:on
ppp0 no wireless extensions.
lo no wireless extensions.
eth0 no wireless extensions.
usb0 no wireless extensions.
In the above on next abnormal shutdown wlan3 becomes wlan4.
