wlan0: no probe response from AP 00:18:39:6a:ff:57 - disassociating -> wireless internet automaticly disconects within 5 minutes

Hi,

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

Regards,

Mark

THE LAPTOP MODEL IS: TOSHIBA SATELLITE M45
I HAVE A BUILT IN WIRELESS.
THANKS FOR YOUR HELP MARK!

Please read the following related bugreport:

https://bugs.launchpad.net/linux/+bug/414560

For me, your wireless issue has to do with a regression/bug in the kernel or wireless driver or both (kernel+driver) in Ubuntu 9.10

So I suggest testing the Ubuntu 10.04 LiveCD and see if the issue occurs in Ubuntu 10.04 as well.

I know that the bugreport 414560 is about the ath9k drivers and your card uses the ath5k drivers, but the behavior and log output is still the same in both cases....
