Have you tried installing WICD and removing network manager? On my installs I have never managed to get network manager to work. So sometimes WICD is a helpIf you find WICD does make your system work please report a network manager bug.

Install WICD from the software centre using your cable. Then type the following in the terminal

sudo apt-get remove network-manager
sudo /etc/init.d/wicd restart

Hey that didn't work either. So i uninstalled WICD.. I have tried tons of things. It is weird because my little wifi light below my screen has yet to turn on.....Iknow my wireless card is supported i just cant get it to work..

peter b (b1pete) said : #3

- pls reinstall network manager; AFTER it is done reboot WITH a WIRED connection (ethernet cat5 cable with rj45 terminals) made between pc and your router

- after boot process complete do you have a net connection ?

- pls open a terminal and run commands as follows (in order listed)

lspci -vnn
sudo ifconfig
sudo iwconfig

- pls post the output of above cmds here. either me or somebody else will help you further.

Travis (t-neu07) said : #4

Okay I connected the ethernet cable and typed in those commands .... I do have a connection via ethernet to modem

broadcom wifi interface is not there. proper drivers should b installed

first url should take care/resolve your problem. second url is just interesting reading - it also refers to first url that sorted out the problem for other users (#30, 31 ...)

Okay so on the first url i did what it told me to do and the Ubuntu software center popped up and said..." A later version is already installed" the wireless still did not work and the button for INSTALL was shaded out so i could not click on it...... Then i tried the alternate method number 2 and that did not work either.....I am pretty sure i did everything right .........

peter b (b1pete) said : #7

before anything else pls consult and see if

http://ubuntuforums.org/showthread.php?t=1745681&page=3

is applicable to dell 1505 too ; it has to do with alt-F2 not being mapped on dell's 1501 and quite possible with1505. see if after removing and blacklisting the module the wifi works. if it does not then

there is a driver conflict/s somewhere; pay special attention to

.......
open the ‘Synaptic Package Manager‘ and search for ‘bcm’
uninstall the ‘bcm-kernel-source‘ package
make sure that the ‘firmware-b43-installer‘ and the ‘b43-fwcutter‘ packages are installed

type into terminal:

cat /etc/modprobe.d/* | egrep '8180|acx|at76|ath|b43|bcm|CX|eth|ipw|irmware|isl|lbtf|orinoco|ndiswrapper|NPE|p54|prism|rtl|rt2|rt3|rt6|rt7|witch|wl'

(you may want to copy this) and see if the term ‘blacklist bcm43xx‘ is there
if it is, then type cd /etc/modprobe.d/ and then sudo gedit blacklist.confput a # in front of the line: blacklist bcm43xxthen save the file (I was getting error messages in the terminal about not being able to save, but it actually did save properly).
........

instructions as shown on url 1 above. ALSO pay attention to ALL user feedback on url 1 ; they are v specific and solved this issue for quite a few users.

Travis (t-neu07) said : #8

okay that didn't work either however I think it does actually have something to do with my keys nto being mapped...I followed your Url you most recently sent me but I didn't really understand what they wanted me to do. I tried but I dont thikn i did it right.

Travis (t-neu07) said : #9

Hey I got it Thanks so much!!!
