Hi,
wireless connection was not working so I past those commands in the terminal
sudo rmmod -f iwl3945
sudo modprobe iwl3945 disable_hw_scan=1
sudo su
echo -e 'alias wlan0 iwl3945 \noptions iwl3945 disable_hw_scan=1' > /etc/modprobe.d/iwl394 col
after that wireless starts working and I browsed internet and there was no problem but after restarting my laptop I couldn't brows internet whoever wireless is working and I can get good signal

It looks like you may have had a typo in your last command. The correct command should be:
echo -e 'alias wlan0 iwl3945 \noptions iwl3945 disable_hw_scan=1' > /etc/modprobe.d/iwl3945
Try that. If it still doesn't work upon reboot, there are other ways to fix it, so please let us know.

That command needs to be run as root, so use sudo:
sudo echo -e 'alias wlan0 iwl3945 \noptions iwl3945 disable_hw_scan=1' > /etc/modprobe.d/iwl3945
Sorry, I should have mentioned that yesterday.

Same problem (bash: /etc/modprobe.d/iwl3945: Permission denied)

Alright, run this:
sudo -s
cd /etc/modprobe.d/
chmod +w iwl3945
chmod +x iwl3945
echo -e 'alias wlan0 iwl3945 \noptions iwl3945 disable_hw_scan=1' > iwl3945
If that doesn't work, please post the output of:
cat /etc/modprobe.d/iwl3945
ls -al cat /etc/modprobe.d/iwl3945

Usually the > command does not work with a protected file because it does sudo the first half before the > but can't for the second half. Another way of doing this is:
echo -e 'alias wlan0 iwl3945 \noptions iwl3945 disable_hw_scan=1' | sudo tee -a /etc/modprobe.d/iwl3945

Alright, it looks like things should be the way they should now. If you reboot do you still have issues with wireless?
