Ubuntu 11.04 on Dell Inspiron... Wireless Completely Disabled


I recently upgraded from Ubuntu 10.4 to 11.4 on my Dell Inspiron laptop, and now my wireless is completely disabled, and I do not have an ethernet cord I can use. (I do not have internet access at home, I rely on public wifi.) Anyone have any suggestions?

Thank you!

I recommend using the Additional Drivers application to see if a "restricted" driver is available/necessary for your hardware. A lot of Dell laptops have Broadcom wireless...

Thank you! But I'm wondering how I would be able to get the necessary driver without internet access?

Also, my wifi worked fine pre-upgrade....

If you have Broadcom wireless (just a guess on my part) then you might find these instructions helpful, they have a "no internet access" section:

I believe I do have Broadcom, however I am confused as to how to locate and install b43-fwcutter. it seems to me that the location specified is online?

First things first, you need to find out which card you have using:

Code:
lspci -vvnn | grep 14e4

According to the wiki your card is supported by either (your choice) b43 or STA:

Thank you! But how would I navigate to the "install media"? I cannot locate ../pool/main/b/b43-fwcutter/ or ../pool/main/p/patch/ on my computer. These files are there, and not online?

The "install media" is the Ubuntu 11.04 CD in your CD-ROM drive (or mount the .iso file directly).

I'm sorry.... You're going to have to break this down for me further... I'm a n00b. I do not have 11.4 on a CD, I upgraded from 10.4, which I had on my system. This has been such a pain for me, I'm about to see if I can reinstall that on my system and just never update Ubuntu again, haha. But I really appreciate all of your help.... If you're able to speak in Ubuntu baby language, then maybe I won't have to reformat my entire drive.... Ha!

Honestly I do it by plugging in to a wired ethernet connection, I have never had to do it without a working internet connection, so best I can do is point you toward the official instructions.

In the off-chance you already have the driver installed from before, but not activated, you could try:

Code:
sudo modprobe b43
or

Code:
sudo modprobe wl

Well, how about this:

So I downloaded the patch discussed here: http://www.linuxquestions.org/questi...l-2-6-37-3558/

It's a .tar.gz file. I unpackaged it, and I thought I almost had it installed, but the ./configure command just wouldn't work. Anyway you could give me detailed directions on how to apply this patch?

Thanks!

I clicked the patch link but it meant nothing to me, sorry.

Did you try "sudo modprobe b43" or "sudo modprobe wl" yet?
