Question #77436 on Ubuntu changed:
https://answers.launchpad.net/ubuntu/+question/77436

    Status: Open => Answered

Mark Rijckenberg proposed the following answer:
Did you follow steps 1 to 5? Did you first enable SSID broadcasting and
disable encryption on the router before testing the wireless connection?
Are you using wicd instead of networkmanager?

You could also try changing the router parameters so that it transmits
on a different channel, for example: channel 3

If wireless still does not work after testing all that, please connect
the pc to the wireless router using an ethernet cable and then follow
this procedure, in order to replace the ath5k driver with the ath_pci
driver (madwifi driver) :

You need a working wireD internet connection to be able to execute the
following procedure:

Step 1: Open Terminal from "Applications->Accessories->
Terminal"

Step 2: Run the following commands (copy-paste each line into the
Terminal, press <enter> after each line)

sudo aptitude update

sudo aptitude install build-essential subversion

cd ~

wget http://snapshots.madwifi-project.org/madwifi-trunk-current.tar.gz

tar xvf madwifi-trunk-current.tar.gz

cd madwifi-trunk-r4079-20090712

make

sudo make install

gksudo gedit /etc/modules

# Now add the Atheros kernel module ath_pci to the list of modules to be
automatically loaded at boot by adding

ath_pci

# to the end of the /etc/modules file. (Gedit editor automatically
opens)

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

# Now add the following 3 lines at the end of the
/etc/modprobe.d/blacklist.conf file:

blacklist ath5k_pci
blacklist ATL1E
blacklist ath5k

# Now you can reboot and it should work.
