ubuntu wireless card config...
 

hey all, i got a fun one this time. i am running ubuntu 6.06 dapper drake on a compaq presario 2100. I have a Linksys Wireless-G card. The model number is: WPC54G Ver. 3.

I have been looking at tutorials online for almost 3 weeks now, and I just can't figure out how to make this thing work. If I plug my ethernet cable into my laptop, the internet does work.

Right now, I can configure my eth0 and eth1 settings via /etc/iftab and /etc/network/interfaces.

so, here is the two files i know that control it:
------------------------
/etc/iftab:
# This file assigns persistent names to network interfaces.
# See iftab(5) for syntax.

eth0 mac 00:13:10:F7:66:6E arp 1
eth1 mac 00:0b:cd:55:f0:50 arp 1


/etc/network/interfaces:
auto lo
iface lo inet loopback

#auto eth0
iface eth0 inet dhcp

auto eth1
iface eth1 inet dhcp

auto wlan0
iface wlan0 inet dhcp



and here is my ifconfig output:
eric@eric-laptop:~$ ifconfig
eth1 Link encap:Ethernet HWaddr 00:0B:CD:55:F0:50
inet addr:192.168.0.6 Bcast:192.168.0.255 Mask:255.255.255.0

wire
and here's my iwconfig output:
eric@eric-laptop:~$ iwconfig
lo no wireless extensions.

eth1 no wireless extensions.

sit0 no wireless extensions.


i know iwconfig should have something in it. my wireless card does work under windows, so i know the card is good.

thanks for any help!

Okay, seems you should check to see if ndiswrapper is installed,

"lsmod | grep ndiswrapper"
should return some thing like this:

ndiswrapper 177364 0
usbcore 130692 3 ndiswrapper,uhci_hcd

Then do

"ndiswrapper -l"
should return something like this:

Installed ndis drivers:
<your w32 driver> driver present, hardware present

-where <your w32 driver> is the <driver>.inf taken from the CD that came with the card. (According to the hardware compatability page here:

https://help.ubuntu.com/community/Wi...CardsSupported
)

(If you're not able to find ndiswrapper at this point...well, there are a lot of good how to's out there. Install ndiswrapper and driver, then see what happens.)

After that I can either do:

"ifdown -a"
"ifup -a"

or find/configure from 'Applications' menu (using Ubuntu /GNOME-flavored linux distro) using whatever network tools are available. Further problems have since been handled by diabling the interface, unplugging/replugging the card, and re-enabling the connection from task bar.

Hope this helps.

Thanks for the reply. I ran the commands you told me to run, and this is what it came up with. I noticed ifup -a returned something about eth0 not being able to come up.

eric@eric-laptop:~$ lsmod | grep ndiswrapper
ndiswrapper 177364 0
usbcore 130820 3 ndiswrapper,ohci_hcd

eric@eric-laptop:~$ ndiswrapper -l
Installed ndis drivers:
lsbcmds invalid driver!
lsbcmnds driver present

eric@eric-laptop:~$ ifdown -a
ifdown: failed to open statefile /var/run/network/ifstate: Permission denied
eric@eric-laptop:~$ sudo ifdown -a

First problem I see with that; "ndiswrapper -l" should return 3 pieces of information: driver name, and the presence of BOTH the driver and the DEVICE!! Seems you don't have your card plugged in properly or something; it's missing the ever-important "hardware present". Linux should see the card like this:

>
>Installed ndis drivers:
>rt73 driver present, hardware present
>

This is where you lose me a bit. My card is a USB-type. There is a command to list the USB-connected devices, "lsusb". Not sure, but if you know/can find an analagous one for CardBus... At a guess, try "lspci" at the command line. Other places you can find if a device is seen at a basic level are in 'System'->'Administration'->'Device Manager'. You need to get the card physically recognized before going further.

Now second problem, you have two drivers installed. Simple, in terminal, type:

sudo ndiswrapper -e <driver>

where <driver> is the Win32 *.inf, MINUS the .inf part. For now take them both out.

Luck to ya. Get that card recognized, then you can get it online.

http://www.broadcom.com/support/ethernet_nic/4401.php this is where you can download a native linux driver and compile it to work for your system. May have better luck doing so. never had much luck with ndiswrapper.
