Wireless connection problem

Asked by Sean Chung

I have just installed Ubuntu 10.04 netbook version on my laptop.
I do not know how to connect it to my wireless router.
I ve tried 'Connect to Hidden Wireless Network...' I ve entered network name and password but it did not work.
When Vista was installed before it would give me available connectable networks.
My laptop is Dell Inspiron 1501.

Can you give the output of:

sudo lshw -C network

I suggest you use a wired connection and get updated, after a reboot you may just find the OS offers you the driver.

Hi,

Please first connect your network card to the wireless router using an ethernet cable (also known as a LAN cable).

In order to gather essential troubleshooting information about your wireless card, please follow this procedure:

Step 1: Open Terminal from "Applications->Accessories->Terminal"

Step 2: Please copy-paste the following command from the https://answers.launchpad.net/ubuntu website in Firefox into the Linux Terminal. Do NOT copy-paste from the Email message into the Terminal, as that will only copy PART of the command. The command STARTS with the word sudo and ENDS with the word restart. So please copy-paste the ENTIRE command below from Firefox into a Terminal, press <enter>, then enter password when sudo asks for password, then press enter again.

Tip: If you have a wheel mouse or 3 button mouse you do not need to type commands into the Terminal. Highlight the command written on the page. Move your cursor anywhere in the Terminal and press the wheel or middle button. Automatic Copy and paste! No spelling mistakes! No Typos! No other errors!

sudo apt-get update; sudo apt-get install hwinfo grep; sudo lshw -C network; rfkill list; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; sudo lshw -short; uname -a; dmesg | egrep 'acx|at76|ath|b43|bcm|CX|eth|ipw|irmware|isl|lbtf|ndiswrapper|NPE|ound|prism|rtl|rt2|rt3|usb|witch|wl'; iwconfig; grep b43 /etc/modprobe.d/*; grep wl /etc/modprobe.d/*; sudo hwinfo --netcard ; sudo lsmod; cat /var/lib/NetworkManager/NetworkManager.state; sudo /etc/init.d/networking restart

Step 3: Please post results (copy/paste terminal output) on this thread. The troubleshooters here need to see the full Terminal output from running the above command.

Regards,

Mark

After reboot it did offer me the driver for the wireless card.
I installed it and it is working now.

I have just newly installed my first Ubuntu 10.04 LTS on my laptop Compaq Presario V5000, as alternated OS. Win is XP.
My wireless network deos not work at all but LAN is ok. On windows it will start automatically when enabled.
I have already tried to follow the troubleshooting instructions but no use.

Kindly advise me best.
