wireless not working (dual boot Windows 7) It works in windows.

[briandeyoung]

I have a dual boot Windows 7 Ubuntu (Studio) 11.04 (codename natty) 2.6.38-11-generic in an HP Pavilion dv7 machine. The wireless doesn't work. Wired is slow (Comcast), but fine in Windows.
I am typing, because I am using a different computer to enter this info, so I apologize in advance.

and a bunch of IE: unknown: and some numbers...

[briandeyoung]

I would appreciate any help here. What information should I provide? Where should I look? What am I missing? I had great success with the 32 bit install. I read a bunch and talked to some and it seemed like 32 is getting obsolete. I want to do both movie editing and sound recording and editing. It seemed like Ubuntu studio 64 was the very best choice. Now, I cannot connect wirelessly and have some trouble with wired connections.

Please, help me!

Thanks,

Brian

Hi, Try this and see if it works please, do what is in post 7.
http://ubuntuforums.org/showthread.p...2#post11121782
Thank you

[briandeyoung]

I tried what you suggested. It didn't seem to change my ability to connect. What should I run to see if the changes you suggested worked in the way you thought they might?

i.e. What should I try next?

THANKS!

[wildmanne39]

Hi, if they worked you should be able to connect, please run these commands and post the results here:

cat /etc/lsb-release; uname -a

nm-tool

lspci -nnk | grep -iA2 net

iwconfig

rfkill list all

sudo iwlist scan

lsmod | grep iwl

dmesg | egrep 'iwl|firm|wlan0'

Thank you

THANKS again!


I had to save to a thumb drive as a .doc in order to get this posted. Sorry if there are formatting errors.

[wildmanne39]

Hi, I recommend taking the spaces out of your ESSID.

Please post the results of these commands:

sudo iwlist scan

sudo cat /var/log/syslog | grep -e iwlagn -e firmware -e wlan0| tail -n35

sudo iwconfig wlan0 power off

if this works we will need to make it permanent.
Thank you

Thanks Again for trying to help!

[briandeyoung]

So, although the symbol for internet has a red 'x' and there are no active connections found, the internet seems to be working wirelessly.

THANKS! How do I make this permanent?

[wildmanne39]

Hi, I am guessing the power off is what made it start working.

What is the network you are wanting to connect too?

To make the changes permanent so you do not have to re-enter it after every reboot, run

sudo 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:

#!/bin/sh

/sbin/iwconfig wlan0 power off

Thank you
