Unable to connect to Wi-Fi network after upgrade

[wildmanne39]

Hi, copy and paste this command in the terminal (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 file named wireless-info.tar.gz 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 wireless-info.tar.gz file as a zip file.

If you do not have ethernet either then follow the directions at this link for running the script without internet.

Contents of gksudo gedit /etc/modprobe.d/iwlwifi.c't allow me toonf:

options iwlwifi 11n_disable=1

[wildmanne39]

Hi, please do:

gksudo gedit /etc/modprobe.d/iwlwifi.conf

add

swcrypto=1

like this

options iwlwifi 11n_disable=1 swcrypto=1

Then save and close gedit.

Also if you can ubuntu wireless will work best with wpa2 AES only encryption.

Set the channel to 1 or 11.
Reboot
Thanks

That hasn't worked either.

Hi, did you also do:

Set the channel to 1 or 11.

Thanks

Hi, you have some error messages and my research shows to add wd_disable=1
to

options iwlwifi 11n_disable=1 swcrypto=1

like this:

options iwlwifi 11n_disable=1 swcrypto=1 wd_disable=1

by running this command to open the file then add wd_disable=1:

gksudo gedit /etc/modprobe.d/iwlwifi.conf

then save and close gedit and reboot.
Thanks

[Stretchkev1]

Even after the modification to that file still won't connect to either channel 1 or 11.

[wildmanne39]

Okay before we go further please set your wireless settings in network manager to match the screenshots.
Thanks

[Stretchkev1]

Okay.

IPv6 is set to ignore

and IPv4 DNS Servers is set yo 8.8.8.8, 8.8.4.4

With WPA2 AES security and on channel 11
