Ubuntu - Wireless Realtek Card - Mostly installed but can't connect to wep network
 
I'm not 100% sure where to start - It's been kind of hit and miss. I used ndiswrapper on a windows xp driver to get this as far as I have - on the suggestion of another site I added the following line ...

blacklist bcm43xx

to the /etc/modprobe.d/blacklist file

I hope some of this below helps...

Code:

user@laptop:~$ sudo lsusb

user@laptop:~$ sudo iwconfig eth0 essid virus
Error for wireless request "Set ESSID" (8B1A) :
    SET failed on device eth0 ; Operation not supported.
user@laptop:~$

The problem is that it appears to be seeing my network but I can't connect to it. I have a Netgear AP (Not real old) and I have it set for WEP 128 - Mix - Even tried it w/o WEP just to see if that was the issue and I still couldn't get connected.

I have the SSID in the Network manager applet correctly and the key is correct as well... the above was an attempt to do it manually per some other advice but that just errored out.

I also noticed that after I installed the driver (w/ndiswrapper) that when you go to Administration>Windows Wireless Drivers
it shows under currently installed windows drivers:
Hardware Present: No
(yet oddly the hardware seemed to be able to sense my wireless network as well as one that must be barely in range if the signal strengh is accurate)

Any suggestions? (More of a newbie at this point as well if that gives you any indication)

Thanks

BTW - New Gateway Laptop (wubi install of Ubuntu 7.04 with Vista)

EDIT : AND I just rebooted and now the wireless connection disappeared from my network settings box

I would connect using wlan0, something like;
modprobe ndiswrapper
ifconfig eth0 down
ifconfig wlan0 up
iwconfig wlan0 essid virus
iwconfig wlan0 key whatever
dhcpcd wlan0

ugh
 
comprookie2000 - those didn't make any difference,unfortunately.

Update : have reinstalled Ubuntu (clean) and followed the guidance in the following 'how to' but the only difference this time is that I can reboot and my wireless configuration doesn't disappear altogether.

It looks like it's trying to connect but it just never does. Even if I turn off the WEP on the AP.

I've been at this for SO LONG - Anyone have any other suggestions?

Some more information that will hopefully help...
 
Using a netgear access point with WEP128 and no ssid broadcast

Code:

lsusb -v | grep Wireless
    iConfiguration          4 Wireless Network Card

and

dmesg | grep Wireless
[  24.948000] wlan0: ethernet device 00:c0:a8:f2:17:b0 using NDIS driver: net8187b, version: 0x1, NDIS version: 0x500, vendor: 'Realtek RTL8187 Wireless LAN USB NIC                                    ', 0BDA:8189.F.conf

Is there anything else I can post that might make this easier for someone to troubleshoot?

Thanks

What guide did you use, this one;
https://help.ubuntu.com/7.04/interne....html#wireless

ryanbelv 09-15-2007 04:00 PM

No this one...
 
This is the one I was looking at...I know it's for a dell with a different card but the procedure seems like it should be the same. Obviously I substituted my winxp driver for the one they're showing as a dell driver

Change this (if Feisty) - yes, even if you have the SSID in the Nework mangler on the client. Seems the devs decided to require this and not tell anyone. My wifi that worked on Edgy stopped after Feisty install - broadcasting SSID was the fix.

Yeah I saw that on the Ubuntu forums and tried it already...didn't change anything...but I'll turn it back on again if you think it'll continue to cause problems. (i.e. maybe that's only part of the issue?)
