9) Restarting the network:

* Running /etc/init.d/networking restart is deprecated because it may not enable again some interfaces
* Reconfiguring network interfaces...
But my internet works fine with Windows 7 which is the other OS in my laptop. Kindly help me in solving this problem. Thanks in advance.

I think you need to install the drivers manually.

pdc
September 13th, 2011, 07:59 AM
have a read at this guide;

it seems the most detailed around

http://www.techytalk.info/ralink-rt3090-ubuntu-driver-ppa/

(I understand that from 2.6.38 version, the driver is included in the kernel)

let us know how it goes;

fdrake
September 13th, 2011, 09:46 AM
before playing around with the drivers can youn please post the results of:



sudo ifconfig wlan0 up
rfkill list all
nm-tool


from the following results that you posted it looks like your card is switched in "OFF" mode.

There are two drivers loaded rt2860sta and rt2800pci, the latter is in better development right now. Unload both, reload the right one, and blacklist the wrong one:


echo "blacklist rt2860sta" | sudo tee -a /etc/modprobe.d/blacklist.conf
sudo modprobe -rf rt2860sta rt2800pci
sudo modprobe -v rt2800pci
This


wlan0 IEEE 802.11bgn ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=off
means, that there is a button/switch, etc, the card is "off". Also check the BIOS settings.

Please show:


rfkill list

Thanks a lot for your reply. Unfortunately my wireless was off. Sorry for not checking that.



I have edited my original post(ifconfig and sudo lshw -C network) with updated results after ensuring that the wireless is On.Here are the outputs of few other commands. Kindly help me in fixing this.

cab you try:


sudo rfkill unblock all

and see if there is any improvement. you may need to reboot. if nothing happens try to follow praseodym steps.

praseodym
September 13th, 2011, 07:45 PM
Try


sudo rfkill unblock all
You may unload the module acer_wmi:


sudo rmmod acer_wmi

Thanks for your quick replies. Even after trying these steps, the problem remains. After executing the commands, i rebooted to machine and still unable to connect to internet.

I am yet to try post 4 and post 6 by pdc and praseodym. Just want to update you with the results after turning on the wireless.

pdc
September 14th, 2011, 02:59 AM
praseodym is right: do as he says:

you have two drivers available;

You will not have wireless with two drivers competing.........

.....do as prasedym told you to do: blacklist rt2860sta as he said below


echo "blacklist rt2860sta" | sudo tee -a /etc/modprobe.d/blacklist.conf
sudo modprobe -rf rt2860sta rt2800pci
sudo modprobe -v rt2800pci



and after doing that, I think you should again tell the forum what you get with


rfkill list all

if all is unblocked, you should be able to configure;

if not repeat the commands and copy and paste the results back to the forum

SyncMr
September 15th, 2011, 02:31 AM
Here are the results

after you have done the commands in the previous post (you may need to reboot for the last one to take effect) in case of negative results, can you post the outputs of

can you run this :


sudo modprobe -r acer-wmi
echo "blacklist acer-wmi" | sudo tee -a /etc/modprobe.d/blacklist.conf
sudo rm -R /sys/devices/platform/acer-wmi/*
sudo modprobe -r ideapad_laptop
sudo modprobe -v ideapad_laptop

reboot


sudo rfkill unblock all

if the problem still persists post results for


rfkill list all
lsmod
less /etc/modprobe.d/blacklist.conf

And I am unable to find devices folder. Should I try some different commands as ideapad_acpi is not found. Would you like to see results of any other commands.?

I did a kernel upgrade by following the link, http://marcin.juszkiewicz.com.pl/2011/06/20/linux-3-0-under-ubuntu-natty-11-04/

The kernel upgrade ended up with Black screen. http://www.thinkdigit.com/forum/images/smilies/icon_sad.gif I installed Linux 3.0 kernel image, module init tools and procps. Then did a reboot and chose ubuntu in bootloader. After that am stuck with black screen.

So I logged into the earlier kernel version of ubuntu to recover from the blackscreen and found that Wireless network works. http://www.thinkdigit.com/forum/images/smilies/icon_smile.gif

Now shall I proceed with removing the older kernel (as internet is working here).? Will the wireless connection work in the upgraded kernel too.?

make sure you install backposrts package first this should prevent the kernel upgrade from editing your wireless modules


sudo apt-get install --reinstall linux-backports-modules-wireless-generic


i am a little bit confused how did you exactly managed to fix the problem? what did you do?

But I have already done the kernel upgrade. I thought of upgrading the kernel and giving it a try. After that when I logged into the older kernel version, my wireless popped up stating that wireless connection are available. I was able to connect successfully.

But the internet is very very slow. It is proceeding in bytes per second. And frequently am getting Problem loading page.

And I am still unable to log into the upgraded kernel. Wondering if I should remove the earlier kernel version as internet works fine here.

i don't think the problem has nothing to do with the old kernel but you can try this
login into your old kernel and run


sudo aptitude purge linux-image-3.0-1-generic linux-headers-3 linux-image-3
echo "deb http://archive.ubuntu.com/ubuntu natty-backports main universe multiverse restricted" |tee >> /etc/apt/sources.list
sudo aptitude update && sudo aptitude upgrade

then upgrade again the kernel to 3 if you wish. This time you should be able to login normally.

Now am not able to connect to internet. i.e.Am able to see the wireless connections. On giving connect, the wifi icon on the top right keeps connecting and prompts for password. I am giving the exact password but in vain. And not able to browse internet.

Now am able to connect to internet. i.e.Am able to see the wireless connections. But not able to browse internet.

are you using the new kernel, right?
edit: i edited after seeing your edit... so there is a problem with the password. are you able to connect to an open network?
can you post the result for



nm-tool
sudo iwlist scan
less /var/log/syslog | grep -i network | tail -100


also with a wire connection can you install the following package


sudo aptitude install wpasupplicant
