Lost wireless connection after upgrading to 11.04

Asked by Cary Devlin on 2011-06-25

I upgraded from 10.10 to 11.04.
  With 10.10 both wired and wireless connections worked perfectly.
11.04 wired only works.
   I have a Dell Inspiron 1520 with a BCM 4311 802.11b/b Wlan internal wireless card.
I have tried everything I know to get the connection to work.
  This is probably a simple issue and I am stumped.
Thank You

Please run to give us an idea of what hardware you have and what driver you are trying to run:
lspci -vvnn -d 14e4:*
sudo lshw -C network
lsmod

it seems that 11.04 has problem connecting to certain wireless routers. i have a linksys wireless and it won't connect to it. however, 10.04 works fine.

Ubfan (ubfan1) said : #5

Choices are wonderful, but having two drivers to choose from can lead to configuration problems -- you appear to have parts of the b43 driver configuration and parts of the Broadcom wl (or STA) driver. The b43 driver is present by default, and all you had to do was load the firmware for it. The way to load this firmware is to either install package firmware-b43-installer (for your chip) OR to install package b43-fwcutter with an internet connection and accept the offer to download the Broadcom files. That should have given you a working connection. By loading the "Additional Drivers" Broadcom STA driver, you also SHOULD have gotten a working connection, but it looks like the process didn't successfully remove all the b43 pieces. See the link for details on setting up wireless for b43 chips:
https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx#b43%20-%20Internet%20access
  You didn't post the output of the lsmod command, so we don't know what driver (wl or b43) is actually loaded.
Why don't you disable the Additional Drivers Broadcom driver, and install the firmware (as described above). I run the b43 and use the open firmware from the firmware-b43-installer package on a linksys router with no problems. I don't run natty much, but it works fine with my hardware.
Good Luck

Here is the output of the ismod command.
The first command was previously sent.
  Sorry, I am not meaning for this issue to be getting so confusing.
I am not an expert, which I have mentioned.
Thank You for your help.

That's not the output from lsmod (not ismod!).

I copied and pasted the command right from the link.
Sorry, I will do it again and send it and remember, I am not an expert
at this and having to deal with a wireless issue in a stable, not beta
release, is a hassle.

Cary Devlin (crdevlin1) said : #9

I am not how I did it and I downloaded BCM 43 wireless and firmware cutter
again and my wireless connection works.
