i lost my wireless connection on my ubuntu 10.4

Asked by bard

My wireless connection suddenly disconnected and I cant reconnect anymore on my wireless network. I have been using this laptop to connect to the internet via wireless for almost 5 months now and now I cant. I have cable internet and my router is a dovado umr.

It is not the router nor the cable modem is the problem because I am able to connect to my wireless network using my other laptop which also has ubuntu 10.10 on it.

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.

Step 4: Please also specify the exact model and make of your PC (if known) on this thread

Regards,

Mark

Hi Guys,

While I was waiting for a reply in this forum yesterday, I was able to resolve the issue. I'm not really sure if this was the problem. But what I did was I uninstalled the wireless drivers in the ubuntu software center and reinstalled them (i.e., compat wireless linux modules for version 2.6.32 & backported wireless drivers for generic kernel image). I tried to reconnect afterwards and I got connected.

If the problem occurs again, I will copy paste the commands in the email and post the results. (But I can still post the results if you still want it, just tell me).

Thanks for the help.
