no wireless icon / option after updating ubuntu 12.10

[praseodym]

Try to add the product and vendor ID to the driver rt2800usb:

echo 'install rt2800usb modprobe --ignore-install rt2800usb ; /bin/echo "2001 3c1e" > /sys/bus/usb/drivers/rt2800usb/new_id' | sudo tee /etc/modprobe.d/rt2800usb.conf

This is one line, you better copy/paste it. Reload the driver:

sudo modprobe -rfv b43
sudo modprobe -v rt2800usb

Check:

iwconfig
lsmod
dmesg | grep rt2
rfkill list
sudo iwlist scan

To uninstall the wrong driver:

sudo dkms remove -m Ralink_5370sta -v 2.5.0.3 --all

I have no words, great thank you
can you explain what I just did and how to avoid it on the next update

[shaital]

oops, after restart the wireless is gone again

[praseodym]

Please show after rebooting:

lsmod
egrep 'rt2|b43|rt5|rt7' /etc/modprobe.d/*
cat /etc/modules

You added the ID of the stick 2001:3c1E to the native driver rt2800usb, when this stick is plugged in.

[praseodym]

Open the file:

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

and remove the line:

blacklist rt2800usb

Save and close. After that open this file:

gksu gedit /etc/modules

and remove b43. Save, close and reboot. Or instead of rebooting, load the driver:

sudo modprobe -rfv b43
sudo modprobe rt2800usb

Check again:

iwconfig
dmesg | grep rt2
sudo iwlist scan
rfkill list

I had this SAME PROBLEM AND FIXED IT! Stop using the Windows/Proprietary driver and use the generic one included with Ubuntu. BAM! Should work....
