View Full Version : [ubuntu] [SOLVED] Need help with wireless on Dell Inspiron 1505

I've tried all the advice I can find on this forum, including using ndiswrapper to install a fresh driver for the wireless card and editing the network interfaces file, but the wireless connection just won't work (I'm using a wired connection now). I'm a noob (cf. my user name!) and am at wit's end. Any help from those more experienced much appreciated.

Thanks. Details:

The command ~$ sudo lshw -C network gives the following (note the "Network DISABLED" statement near the end):

*-network

ifconfig gives me (keeping in mind that I'm wired in):

And the network interfaces file reads as follows:

auto lo
iface lo inet loopback

iface eth0 inet dhcp

auto eth0

OK, found a possible clue. I went back to the live CD, and it identified a missing piece of firmware, which I installed. Then, voila! I had wireless networking--all the nearby networks were visible, and I was able to log onto mine and access the Internet, use Firefox, etc.

However, when I removed the live CD and rebooted from the hard drive, I was back to the same non-wireless status (also, oddly, my sound stopped working, and again, it was fine with the Live CD).

Would a reinstall from the live CD be indicated? If so, will I be able to save my Windows partition (which I still need for some purposes)?

Thanks.

Use sypnatic to remove Network Manager (including the gnome counterpart) and wicd.

Try these commands at the terminal & post the output here


dmesg | grep ndiswrapper
ndiswrapper -l


dmesg | grep wlan
cat /var/log/messages | grep wlan


ifconfig
cat /etc/network/interfaces


iwlist wlan0 scan
iwconfig wlan0

Are you trying to connect to an encrypted wireless network? Is it WEP or WPA?

Thanks for the reply. Yes, the network is encrypted with WEP, but I don't think that's the issue. First, when I connect with a cable, the encryption isn't a problem. Second, I turned the encryption completely off and still had the same problem.

Here are the answers to the terminal commands--any clues?

Can you also post your lshw -C network? The information you posted in your earlier post should now be different since you have installed NDISwrapper.

Your wireless adapter is not picking up any wireless network at all.

Please run each of these commands at the terminal & post the output here

dmesg | grep ndiswrapper

dmesg | grep wlan

cat /var/log/messages | grep wlan

uname -mar

Here is the result of lshw -C network:

Still showing network as DISABLED. (The card is ENABLED in the BIOS, I already checked that).

Solved, kind of. All my playing around hosed my Windows partition (luckily everything is backed up), so I just reinstalled Ubuntu on the entire disk. I then reinstalled b43-fwcutter, which was the firmware the Live CD identified, and voila, my wireless network appeared.

I'm finding the computer to be clean, quick, and fast, which is great. If I decide to reinstall Windows, I may do so via Parallels or a similar solution.

Thanks to everyone who responded.
