Failed to bring up wlan0
Hi folks,
I have a Dell Latitude D620 laptop that dual boots WinXP and Ubuntu 6.10. I'm trying to get the built in Intel wireless card to work using 'ndiswrapper'. I can see the wireless card in a 'lspci'. I've downloaded and installed the Windows driver using 'ndiswrapper -i', and a 'ndiswrapper -l' shows 'driver installed, device installed'. I have also added the following to /etc/network/interfaces: Code:
iface wlan0 inet dhcp Code:
root@ubuntu:/etc/network# ifup wlan0 Thanks for reading. Admins - Sorry for the double post :S |
sudo modprobe ndiswrapper
iwconfig sudo ndiswrapper -m On iwconfig, check to make sure your card is listed. If it isn't, don't run ndiswrapper -m, post back here. |
Hi AstronomyDomine, thanks for getting back to me.
I've already run the 'ndiswrapper -m' as part of the install process from the tutorial I originally followed. I can see it in there: Code:
modprobe -c | grep -i ndiswrapper Code:
iwconfig Code:
lspci | grep Wireless Do I now need to remove ndiswrapper from modprobe? Thanks again for your help. |
Try this:
modprobe -r ndiswrapper reboot ndiswrapper -l modprobe ndiswrapper iwconfig Reboot will of course reboot your computer. On ndiswrapper -l make sure is says that the drivers and hardware are present, copy the output to this thread. If it does say that both are present, try to modprobe ndiswrapper, then check iwconfig for your card. Have you updated your kernel recently or modified anything that may have broken ndiswrapper? |
I haven't updated my kernel, uname shows '2.6.17-10-generic'.
Here's the output, I'm getting an error from modprobe: Code:
root@ubuntu:~# ndiswrapper -l Code:
root@ubuntu:/lib/modules/2.6.17-10-generic/kernel/drivers/net/ndiswrapper# ls -la Do I need to remove and regenerate this somehow? Thanks. |
Don't know if this is worth mentioning, but I just found something about the wireless card in /var/log/messages:
Feb 8 21:25:16 ubuntu kernel: [17179588.980000] ipw3945: Detected Intel PRO/Wireless 3945ABG Network Connection There's a few that look like that.

This must have come with Ubuntu. |
Hmm. I've had error before and it was because adept updated my kernel and ndiswrapper was only installed under the old one. How did you install ndiswrapper? With apt or through make install? Either way, I'd try uninstalling it and reinstalling it. You may need your kernel headers/source though, so I'd suggest hooking up your laptop to the internet with an ethernet cable and using apt to install everything.
Good luck. |
I just reinstalled Debian Etch and i figured out that for some reason the interface has changed its name to eth1. Just replace wlan0 in /etc/network/interfaces with eth1 and retry. You need to write 'ifup eth1' and/or 'dhclient eth1' instead of 'ifup wlan0' and 'dhclient wlan0' if you want to bring it up manually.

I had an issue similar to this. I would get the message "No wireless extensions". I had to recompile my kernel, the support for wireless cards was not enabled.
|
I've managed to fix this. After finding the ipw3945 processes, I read up on this.
I removed all traces of ndiswrapper and restored all the config files I had changed. I then used Synaptic to download and install network-manager-gnome, and rebooted. After the reboot I could see several wireless networks from within network-manager, chose mine, and everything is OK! Thanks for everyone's help with this though! ** RESOLVED ** |
HELP!!!!
I tried using Vista x86 and x64 drivers with ndiswrapper. Neither appeared to work.I thought I had to use ndiswrapper, but as I was browsing around the web to find the windows driver, I found a linux driver, so I began to follow the directions, but got stuck while running a command didn't work. I have no experience with wireless in Linux. Code:
chris@ubuntu:~/Desktop/rtl8185_linux_26.1027.0823.2007$ ls /etc/network/interfaces Code:
iface wlan0 inet dhcp |
Start a new thread, add a real title
fakie_flip:
Why are you tacking onto a 10-month old thread? Start a new thread and please use a meaningful title. "HELP" is not helpful to anyone. |
I did start a new thread a long time ago, and no one replied. That is why I am saying HELP!!!!!!!!!!!!!!!! I don't want to have to switch back to Windows just to have internet.
|
And I'm having a very similar problem. People always say to search the forums before posting, and that's what I did. I found this thread, so I'd like to know what the solution is. I also get this error.
wlan0: ERROR while getting interface flags: No such device |
Fakie, PLEASE stop spamming the forum with your problem. You have multiple threads on this and you are actively getting help. For Pete's sake, keep it in one place.

one solution..
I was playing around with b43 drivers on ubuntu (lucid, BackTRack 5 R1, hp presario notebook) and I got the same error "wlan0: ERROR while getting interface flags: No such device" . I think I had run $modprobe -r b43 , at some time.
Resolution: $modprobe b43 , fixed the error |
I have just one question: why you want to use ndiswrapper and windows driver, when you have native linux driver?
