Can't Connect to Wireless Networks

[dinodxr]

First of all, hi guys! i'm new to Ubuntu, used to be a Windows / Mac user for ages. So.. i wanted to try Ubuntu 12.04 (i tried also 13.04 i was curious) on an old laptop that i have before installing ubuntu as my primary OS in my desktop. i have a Toshiba Satellite M70-191, it runs ubuntu just fine but i can't connect to any of the available wireless networks (free or locked ones) i searched for a driver (probably Intel 915GM) but nothin'. i also saw here in the forums that other users experience problems when trying to connect to a wifi network. Any kind of help or advice?

Hi dinodxr. Welcome to the forums

Could you open a terminal run this commands and paste its results back?

sudo lshw -C network

lspci -nnk | grep -iA2 net

ifconfig

route -n

Regards.

i run the commands, as you said, but didn't had my wifi on. (also sorry for my bad english, italian here)

[papibe]

Thanks.

Your wireless interface is disable.

I have a Toshiba laptop and the button on the keyboard that turns on and off the wireless interface actually works. With that in mind, check if you can enable it from a hardware button, or a custom keyboard shortcut.

Let us know how it goes.
Regards.

[dinodxr]

ok, i found that switch. i got a red light and the network at the status bar shows me some wifi networks. but still can't get on anyone, even mine.

[papibe]

Glad you are making progress.

Try unplugging your ethernet cable and try to connect your own network. What error do you get?

Regards.

[dinodxr]

an error doesn't pop up, it just doesn't connect to any wifi network, even mine. it asks for my password i type and then nothing.

Hi dinodxr, Install ubuntu 12.04 again & driver install in your laptop.

sudo apt-get update
sudo apt-get install linux-backports-modules-wireless-lucid-generic
sudo reboot
create a the file /etc/modprobe.d/ath9k.conf and add the following line to it and reboot
options ath9k nohwcrypt=1

Hi dinodxr, Install ubuntu 12.04 again & driver install in your laptop.

options ath9k nohwcrypt=1

This will not help, because of

a) 12.04, the backports are for lucid (and they contain older drivers)

b) he uses an Intel device, not Atheros

Unfortunately, the ipw2200 device driver is not further developed. Please show the outputs of

lsmod
rfkill list
iwconfig
dmesg | grep ipw
cat /etc/udev/rules.d/70-persistent-net.rules
