Wifi Problem with Dell Inspiron Laptop
Hey guys,
I just loaded Ubuntu 12.04 on my computer and I'm having some trouble. For some reason it seems like it's not able to detect wireless signals.
I was able to access the internet with an ethernet cable at my fathers house, but I was unable to do it at my apartment. I'm not sure if this is relevant but I figured I'd mention it.
I think my problem is fairly similar to the one found in the following thread, but I'm too ignorant to know the difference. :-/
http://ubuntuforums.org/showthread.php?t=1946445
When I opened terminal and typed "rfkill list" It said
0; dell-wifi: Wireless LAN
Soft blocked: yes
Hard blocked: yes
1: dell-bluetooth: Bluetooth
Soft blocked: yes
Hard blocked: yes
I also tried the FN+F2 key combination with no effect.
Please help.
Thanks,
Joe
Re: Wifi Problem with Dell Inspiron Laptop
Hi, looks like you have 2 problem, hardblocked hardware and software
you had to have pressed the F2 key to get into bios to tell the machine where to boot
from. So...press Fn/F2 ONE time and then..
post the results please.
thanks
Re: Wifi Problem with Dell Inspiron Laptop
in terminal:
lspci
also is the wifi switch in the on possition? (I know but it happened to me once.)

Thanks for the advice. Here are the results
bigjoey@bigjoey-Inspiron-5720:~$ rfkill list
0: dell-wifi: Wireless LAN
Soft blocked: no
Hard blocked: no
1: dell-bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
Looks like there's some improvement, but the computer still isn't picking up any signals. There's also a little light on the bottom left hand corner the comes on when it's picking up a wifi signal. That light is still off.

I tried putting that in terminal and this is what it said.
No command 'Ispci' found, did you mean:
Command 'lspci' from package 'pciutils' (main)
Ispci: command not found
bigjoey@bigjoey-Inspiron-5720:~$
There is no one and off switch for the wifi
Re: Wifi Problem with Dell Inspiron Laptop
Hi, I wanted to clear the hardware block first,looks good now
lets take a look at which wifi card you have to get your wireless working.
please enter and post the results of..
Code:
lspci -nn | grep 0280
thanks.
*note lspci ....means ls (list) pci.. (devices attaching to the PCI buss)
the command lspci needs "stuff" after it
Re: Wifi Problem with Dell Inspiron Laptop
Hi, copy and paste this command in the terminal (ctrl+alt+t) please:
Code:
wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script && ./wireless_script
It will download a script and create a text file in your home folder with wireless information so we can see the condition of your wireless at this time and the Mac address, WPA key and WEP key are removed for your security, then reply back and attach the netinfo.txt file.
Thanks
