Unable to access wireless in Ubuntu 10.10

thirstonlinux · 06-10-2012, 12:40 AM

Hi All,

I bought a new Dell Vostro 3550 which has Ubuntu 10.10 pre-installled in it.

It was working fine since it was last updated. After the automatic update, when I enable the wireless on my laptop, Blue-tooth turns on but Wireless still not coming up. It gives a pop up saying wireless disconnected...

I there any service which needs to be runnig for this.

When I do iwconfig the following comes up..

lo no wireless extensions.

eth0 no wireless extensions.

I am very worried about this. Looking for your advise on this..

Do this:

$ lspci -vvv | less

hit the space bar until you get to the wireless adapter. Look what module it uses, or if it's even listed.

For bluetooth:

$ hcitool dev

lists local bluetooth devices. Determine which kernel module to use and load it.

$ modprobe module_name

I'm 99% sure the module for the wireless device is not loaded, but hardware failure can cause this thing also.

When I do lspci it does not show any details about Wireless. What do I do now

What version did you upgrade to? What version did you upgrade from? (I assume from 11.10 to 12.04 LTS) This clearly means that your wireless card is not being detected by the kernel.

I had the same issue on my Lenovo laptop ... I had reinstalled and then the driver for the wireless got installed and started working fine. Trust me nothing else worked - installing the driver manually, upgrading the kernel .. I almost wasted a day ...

I Am using Ubuntu 10.10, It was saying Ubuntu 11 is available for Upgrade. for some reason Upgrade did not take place at all. But I do updated the updates that came for 10.10.

Why dont you upgrade to 12.04 ??? I think do-release-upgrade will take care of everything. But for this, you need ti be connected to internet. Can you connect to internet via your ethernet port now that your wireless is not working?

Please post the output of:

$ lspci | grep -i network

$ lspci | grep -i network

09:00.0 Network controller: Intel Corporation Device 008a (rev 34)

This is wat I get

This is your onboard ethernet card. Reinstall is my choice - from my past experience.

I leave it to others to jump in here though.

How to do it. Could you let me know

abi0909 · 06-19-2012, 12:12 AM

How fast is your internet connection? You will need to do the following:

1) http://www.ubuntu.com/download/desktop --> Download Ubuntu 12.04 ISO from here.
2) http://www.ubuntu.com/download/help/...tick-on-ubuntu --> Use these instructions to burn that ISO into an USB.
3) http://www.ubuntu.com/download/help/...re-you-install --> Boot off from the USB and then "Install" from there.

Remember that you will need internet to download the ISO.
