wlan0 No scan results -> DISABLED Wireless Network controller [0280]: RaLink RT3090 Wireless 802.11n 1T/1R PCIe [1814:3090] not working on MSI CR420 when using built-in rt3090sta driver in Ubuntu 10.04 LTS

Pleae execute these steps and get us the requested informations...

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 aptitude update; sudo aptitude 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 'ound|irmware|eth|ath|wl|ipw|b43|witch|ndiswrapper'; iwconfig; grep b43 /etc/modprobe.d/*; grep wl /etc/modprobe.d/*; sudo hwinfo --netcard ; 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

You love pasting that :D
(seems to work though)

((((((These r shown which i have already tried but not still working...I have even tried with ur full commands in single hit though its not working... Thank you so much for help & wish for more of this solution again...is there any other ways to check???

MSI CR420
CPU : Intel Core i3-330M
wireless adaptor :802.11bgn 1T1R Mini Card Wireless Adapter

Please help for the solution in Ubuntu 10.04.... not detecting & can't scan too

No, that is NOT the full output.

We need the output of this command:

sudo aptitude update; sudo aptitude 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 'ound|irmware|eth|ath|wl|ipw|b43|witch|ndiswrapper'; iwconfig; grep b43 /etc/modprobe.d/*; grep wl /etc/modprobe.d/*; sudo hwinfo --netcard ; sudo /etc/init.d/networking restart

Post the output here

I think we both having the same problem

Command seems worked without any errors. But its not working still. there is a pop-up for wireless in the topmost status bar but its disabled/not functioning except eth0. So, how to search for wireless or how to check whether there is problem of hardware compatibility....Wating for your response & thank you so much guys fo reply..

I am not going to help you any further if you refuse to follow the instructions I gave you....

I have tried with installing qgrubeditor to remove boot menu lists as there are more than 5 options to choose GRUB/boot loader option as i also have windows7 (Dual Boot). this happend after update UBUNTU 10.04 where existing previous GRUB. So, can anyone help me to make listed only 2 operating system that i have installed?
I have installed that software but couldn't make it work as error comes as:::
"it was unable to read/write in one of the following files - /boot/grub/menu.lst, boot/grub/device.map & /etc/mtab.

So, please mention how to remove, modify or something that needs to remove the listed options...PLZ THIS IS JST ATTACHED WITH MY PREVIOUS MSG...

I never said the command would solve your issue right away.

I wrote the following

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

and the following:

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.

But you refuse to follow the instructions.....

Dear Mark,

I am not refusing to your instruction. I have tried but not working still with the command that you mentioned. So, i request for your further help. If you can, plz try in core i3 processors, intel MSI CR420 brand laptop. because in this laptop, i have tried lots of things & only this 10.04 is able to install but only the wifi-problem & i have not yet tried webcam inbuilt. May it works. In this laptop, other previous OS doesn't support where something defects shows some errors while install. So, please i need you & all who r experts. help na...

While trying to your instruction "sudo aptitude update; sudo aptitude 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 'ound|irmware|eth|ath|wl|ipw|b43|witch|ndiswrapper'; iwconfig; grep b43 /etc/modprobe.d/*; grep wl /etc/modprobe.d/*; sudo hwinfo --netcard ; sudo /etc/init.d/networking restart" which i hav tried before too, its shows like ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
root@manae:/# sudo aptitude update; sudo aptitude 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 'ound|irmware|eth|ath|wl|ipw|b43|witch|ndiswrapper'; iwconfig; grep b43 /etc/modprobe.d/*; grep wl /etc/modprobe.d/*; sudo hwinfo --netcard ; sudo /etc/init.d/networking restart

my special thanks goes to Mr. Mark Rijckenberg. I have tried installing the driver "RT3090_LinuxSTA_V2.3.1.4_20100222.tar.bz2" & its worked...Its so gud to feel your help is higher than my expectation...Thanks Mr. Mark!!!

It seems you got it solved by following this procedure:

http://www.halibutdepot.org/how_to_build_rt3090_for_ubuntu_lucid/

Through your inspiration of using the commands that u made me try, i found the driver details & searched driver which i got tar file from "http://www.ralinktech.com/license_us.php?n=2&p=0&t=U0wyRnpjMlYwY3k4eU1ERXdMekF5THpJekwyUnZkMjVzYjJGa09Ea3pOalE1TlRBd09DNWllakk5UFQxU1ZETXdPVEJmVEdsdWRYaFRWRUZmVmpJdU15NHhMalJmTWpBeE1EQXlNakl1ZEdGeUM%3D". So, i extracted it & install with some commands :::

ar xvjf file.bz2
cd file
./configure (This doesn't work.)
make
su
make install

THANK YOU FOR YOUR INSPIRATION...You really helped me to solve my problem & wish to get some more which i gonna drop in this forum like "removing menulists while boot ...
