HP Compaq Nx 7400 - Wireless Card present, networks present, not connecting

**Tymoteusz** · October 20th, 2013

Hi there - I'm another Linux newbie having wireless problems. I've looked around, and tried some troubleshooting, but I'm still having no luck.
From what I've read in this forum, there is some specific information you need, regarding my computer, so I have tried to include as much info as possible below.
Any help would be much appreciated.

Hi, please do:

Code:

sudo apt-get purge bcmwl-kernel-source

reboot does it connect if not then do:

Code:

gksudo gedit /etc/pm/power.d/wireless

(this will create or edit a configuration file that will override the default power management behavior) and enter the following:

Code:

#!/bin/sh

/sbin/iwconfig wlan0 power off

above exit0, then save gedit, close and reboot.
Thanks

**Tymoteusz** · October 20th, 2013

Thanks for that, although I'm no sure if I'm getting it correctly, After

Code:

gksudo gedit /etc/pm/power.d/wireless

it creates empty text file. What should I enter there? Is it supposed to look like that?

Code:

#!/bin/sh/sbin/iwconfig wlan0 power off

**wildmanne39** · October 20th, 2013

It should look like this:

Code:

#!/bin/sh

/sbin/iwconfig wlan0 power off

**Tymoteusz** · October 21st, 2013

OK, so I did it and unfortunately it didn't solve the problem

lshw -C network still shows network as disabled.

**wildmanne39** · October 21st, 2013

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 file named (wireless-info.txt, or wireless-info.txt.tar.gz) 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, click on the paper clip and attach the wireless-info.tar.gz file as a zip file.

If you do not have ethernet either then follow the directions at this link for running the script without internet.

Thanks

**Tymoteusz** · October 21st, 2013

OK. The file is attached as requested.wireless-info.tar.gz

**wildmanne39** · October 21st, 2013

There is an error in your dns server so please set your wireless settings to match the screenshots.
You have two errors in the information you posted one says hardware error detected please make sure your card is setted good after you do the above repost a new wireless file and lets see if the error messages are still there.

Also power management is still on did you save the file and reboot after you edited it?
Thanks
