I've got a Wi-Pi WiFi USB dongle and a Raspberry Pi model B with Raspbian wheezy (updated/upgraded) but I can't get the wipy to work.

Every single time I connect the wipy the Raspberry Pi reboot.

I see these messages on boot:

wifi errors

and of course I don't see wlan0 in wpa_gui.

I've also tried connecting the Wi-Pi a the active/powered usb port of a D-Link USB hub powered at 5V/3A. The RPi didn't reboot this time but still didn't work (same "Failed to bring up wlan0" message when I manually reboot).

How can I get the Wi-Pi working ?

  • Q: What's a "wipy"? – goldilocks Sep 6 '13 at 23:37
  • sorry, meant WiPi, edited the question now. – George Profenza Sep 6 '13 at 23:42
  • Plug wifi adapter before boot.if you plug it after boot it will reboot because lack of power. For failed wlan0 messages, please update your question with contents of /etc/network/interfaces file. – gurcanozturk Sep 7 '13 at 7:36
  • Do you have a DHCP server on your network? The DHCPDISCOVER message indicate that your Pi is trying to obtain an IP address and isn't getting a response back. What does iwconfig display on your system? – HeatfanJohn Sep 7 '13 at 16:09
  • @HeatfanJohn We should do, all other computers get they're IPs assigned by a DHCP server. The problem with iwconfig is I get a segmentation fault when I run the command which is worrying – George Profenza Sep 7 '13 at 17:53

Get ride of that... Get this: Edimax EW-7811Un 150Mbps 11n Wi-Fi USB Adapter

Plug it in, will work fine.

When the command prompt comes up type:

sudo nano /etc/network/interfaces

Then add whatever is missing from this to what you see:

auto lo

iface lo inet loopback
iface eth0 inet dhcp

allow-hotplug wlan0
auto wlan0

iface wlan0 inet dhcp
wpa-ssid "ssid"
wpa-psk "password"

This will be worry free forever.

  • have ordered, one. In the meantime, I've made sure /etc/network/interfaces looks like the above(with the correct ssid and pass of course). This time in the boot sequence things looked better, and the WiPy's led turned on, but once I started wpa_gui I noticed wlan0 still wasn't available. Same result with wicd – George Profenza Sep 9 '13 at 18:29
  • Yea, sounds like the dongle you have is a dud. While it is possible to get the driver for it and install it in the right directory, the one I recommend is going to be totally problem free. – Chase Westlye Sep 9 '13 at 21:26
  • Perhaps, although I have ordered two and it's a bit weird that two would be duds – George Profenza Sep 10 '13 at 9:16
  • Then its probably a driver issue... You can try to tackle that... OR... Just get something that works out of the box ; ) – Chase Westlye Sep 10 '13 at 15:58
  • The WiPY eventually worked, although I'm not happy that the RPi reboots every single time I plug it back into the USB port. The Edimax came today as well and it worked just fine. The RPI doesn't reboot if I remove it/plug it back in and wifi connection is back on, where as the wipy needs a reboot to work. Sticking with the edimax for now. The above config was also handy (thanks (+1)) – George Profenza Sep 10 '13 at 18:08
