7) Ubuntu Version:

Code:

8. Kernel/architecture (including 32 vs. 64 bit):

Code:

uname -mr
  2.6.38-8-generic x86_64

9) Restarting the network:

Code:

  sudo /etc/init.d/networking restart
   * 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.

gentle bounce...

**psrdotcom** · September 13th, 2011

I think you need to install the drivers manually.

**pdc** · September 13th, 2011

have a read at this guide;

it seems the most detailed around

http://www.techytalk.info/ralink-rt3...tu-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

before playing around with the drivers can youn please post the results of:

Code:

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.

**praseodym** · September 13th, 2011

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:

Code:

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

This

Code:

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:

Code:

rfkill list

**SyncMr** · September 13th, 2011

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.

**fdrake** · September 13th, 2011

cab you try:

Code:

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

Try

Code:

sudo rfkill unblock all

You may unload the module acer_wmi:

Code:

sudo rmmod acer_wmi

**SyncMr** · September 13th, 2011

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.
