Can not switch on/enable wireless connection/using Ubuntu 9.10


Hi,

I am new to Linux and I am enjoying it a lot.

The switch of the laptop (HP pavialion dv2000 if it helps) does not turn on the wireless connection. I have been reading the wireless troubleshooting from Ubuntu documentation (https://help.ubuntu.com/9.10/interne...ireless-device) and it says: “Check that the device is on:
1.Many wireless network devices can be turned on or off. Check to see if there is a hardware switch, some devices can be switched off from Windows and may need to be turned back on from Windows”.

I do not know what it means by Windows, does it mean the Windows OS? I really do not think so.

I do not know how to go on. I checked the device recognition using the terminal and it says it is disable...ok, I can I enable it? It may be a silly question but I am a little ignorant with computers.

This is the information displayed from the terminal:
pablo@pablo-laptop:~$ sudo lshw -c network

I had a ton of problems getting wireless to work in Ubuntu 9.10. I fixed the problem by installing WICD. I read comments on forums from multiple people that this is what solved their problems in 9.10 for them also.

In case you are not aware of how to do it--once you download the .deb package for WICD you install it by going to the directory that you downloaded the file to and...
Code:
sudo dpkg -i wicd_1.5.9_all.deb
Just as a note I have used multiple distros on multiple systems and Ubuntu 9.10 is the first time I have ran into any significant wireless problems.

If you prefer to use Synaptic--I believe this package is available if you enable Universe repositories--but I am not sure and not at home right now to check, the above will work (for installing the program) even if it is not available in the repositories. Hopefully this will resolve your wireless problems.

As I said before I am a little incompetent with computers. I could not install WICD as it seems there are some conflicts:


pablo@pablo-laptop:~$ sudo dpkg -i wicd_1.5.9_all.deb
dpkg: regarding wicd_1.5.9_all.deb containing wicd:
wicd conflicts with network-manager
network-manager (version 0.8~a~git.20091013t193206.679d548-0ubuntu1) is present and installed.
dpkg: error processing wicd_1.5.9_all.deb (--install):
conflicting packages - not installing wicd
Errors were encountered while processing:
wicd_1.5.9_all.deb
pablo@pablo-laptop:~$

What do you suggest? Thanks a lot!

First remove networkmanager
Code:
sudo apt-get remove network-manager
sudo dpkg -i wicd_1.5.9_all.deb

Actually, you can simply use
Code:
sudo apt-get install wicd
It will automatically deinstall the standard network manager and install WICD.

I'm using WICD since years and very much prefer it.

Hi, Thanks a lot,

I installed WICD but still does not detect the wireless connections (also the switch in the computer does not activate/deactivate). As an indicator: My life partner is using Windogs and she detect some wireless connections around the house. I will try moving to a cafe-bar with wireless connection. It might be that the connections are too weak.

Good day!

Pablo

Hello again,

Still the wireless does not work, the wireless connections are not detected by WICD. I have tried to search for the answer in the forum but do not find a similar post. I do not know what to do. what could be failing? I have thought of replacing WICD with other program like Wifi Radar or similar. Do you recommend me that?

Thanks a lot!

Pablo

Hi, thanks,

I am afraid the outputs are not very useful.

There you have the outputs:

pablo@pablo-laptop:~$ ifconfig wlan0 down

SIOCSIFFLAGS: Permission denied


pablo@pablo-laptop:~$ ifconfig wlan0 192.168.2.20

SIOCSIFADDR: Permission denied

SIOCSIFFLAGS: Permission denied


pablo@pablo-laptop:~$ ifconfig wlan0 up

SIOCSIFFLAGS: Permission denied


pablo@pablo-laptop:~$ iwlist wlan0 scan

wlan0 Failed to read scan data : Network is down
