[SOLVED] No Wifi interface when booting of USB

[damianv]

Hi Guys,

I have setup my PI up to boot from my USB flash disk and its working great! except I can't get my wlan going..
If I boot from SD it works fine no config needed but from USB its a no go?

Here are some outputs:

Terminal

$ lsusb

$ cat /etc/network/interfaces

iface lo inet loopback
iface eth0 inet dhcp

allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
wireless-power off
iface default inet dhcp

$ sudo ifconfig -a

I'm running beta 1.1

I'm still very new to linux but learning as I go along

@damianv

this sounds like power issue. do you have both wifi dongle and usb storage device attached through powered usb hub?

[damianv]

Hi mk

Thanks for the reply. Yes it seems to have been a power issue. Used the powered usb hub and it has created an interface for the wlan0 now

Thanks for the help!
