False wireless connection on startup

[friedsoup]

Whenever I boot up or return from sleep, my laptop automatically connects to my wifi, but no applications have internet access. Once I disable and re-enable wireless, all applications work fine. What can I do to solve this?

I searched as much as I could to avoid posting a new thread, but I couldn't find this specific problem

Hi, copy and paste this command in the terminal when you can not connect wirelessly using a wired connection (ctrl+alt+t) please:

wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script && ./wireless_script

It will download a script and create a text file in your home folder with wireless information so we can see the condition of your wireless at this time and the Mac address, WPA key and WEP key are removed for your security, then reply back, click on the paper clip and attach the netinfo.txt file.
Thanks

The connection to dropbox times out even with the wired connection.
Can I dl that script with an active connection, then run it after a reboot?

Please try:

echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
sudo modprobe -rfv iwlwifi
sudo modprobe -v iwlwifi

Also change encryption in router to just wpa2 if possible.
