It says "Connected" but it's not

[chili555]

should i create one, even if no connection is shown from scanning?!

No, please. 'Create New Wireless Network' creates an ad hoc computer-to-computer network; that's just what we do not want.

Can you confirm you have the needed firmware rt73bin?

ls /lib/firmware | grep rt7

Also, is the interface up?

sudo ifconfig wlan0 up

If there is an error or warning, it will be informative, so please post it.

I'd studying your readings, as I'm sure the Wild Man is, too...

[d21]

ok, i'll stay far from that then :

meanwhile: thanks for your patience

EDIT:

It is up and gives every sign of being a perfectly working wireless interface. Still no scan results?

sudo iwlist wlan0 scan

Are you certain you are near a working wireless access point?

[wildmanne39]

Hi, you can also try:

sudo iwconfig wlan0 power off

see if that brings it to life.
Thank you

[d21]

nuthin'



a guy from italian forum suggested i could check out for "ndiswrapper"... can it be of some help?

BTW, the strange thing is that i installed ubuntu 11 live from CD, and while on live, internet did work!!!

this is awkward...

[wildmanne39]

Hi, you do not need ndiswrapper, and it usually does not work as well.

Unplug your wired connection then run this command and post the results please:

sudo cat /var/log/syslog | grep etwork | tail -n50

Did you try what I suggested in my last post?
Thank you

[d21]

yes i tried that, but still no scan results...

what you mean about "unplugging my connection?"

the machine with linux has only wireless usb pen, and i'm writing this from another machine with windows 7 + wireless usb pen (same model of the other).

What do i have to unplug?


EDIT:

to be sure i gave the command again and now it gave me this:

anna@computer-cucina:~$ sudo iwconfig wlan0 power off
[sudo] password for anna: 
Error for wireless request "Set Power Management" (8B2C) :
    SET failed on device wlan0 ; Invalid argument.
anna@computer-cucina:~$ sudo iwconfig wlan0 power off
Error for wireless request "Set Power Management" (8B2C) :
    SET failed on device wlan0 ; Invalid argument.

i think this means the settings is already given?

now the led is flashing all the time...

[wildmanne39]

Hi, was the light off before?
Try these 2 commands please:

sudo iwlist scan

iwlist chan

if you do not have a wired connection then just run the other command that I gave you and post all the results of that command here, I am looking for more error messages.
Thank you

Hi, the errors you are getting means it is still trying to use ad-hoc.

Go into network manager and click on create a new wireless connection, then make sure your settings look like this, refer to screenshots.

Also while setting up wireless set security or encryption to wpa2.
Thank you
