It's been a long time since I last blogged. But nevertheless, here a guide on how to install the Asus N13 Wireless USB Adapter. This may also apply to other WLAN adapters that use the rt2800usb kernel module.

The easiest way to fix this regression in the kernel is to downgrade the kernel:

Go to http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.2-precise/ and download the packages

linux-headers-3.2.0-030200-generic_3.2.0-030200.201201042035_amd64.deb
linux-headers-3.2.0-030200_3.2.0-030200.201201042035_all.deb
linux-image-3.2.0-030200-generic_3.2.0-030200.201201042035_amd64.deb

You can do that with wget:

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.2-precise/linux-headers-3.2.0-030200-generic_3.2.0-030200.201201042035_amd64.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.2-precise/linux-headers-3.2.0-030200_3.2.0-030200.201201042035_all.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.2-precise/linux-image-3.2.0-030200-generic_3.2.0-030200.201201042035_amd64.deb

Then install them:

sudo dpkg -i linux-headers-3.2.0-030200_3.2.0-030200.201201042035_all.deb
sudo dpkg -i linux-headers-3.2.0-030200-generic_3.2.0-030200.201201042035_amd64.deb
sudo dpkg -i linux-image-3.2.0-030200-generic_3.2.0-030200.201201042035_amd64.deb

Then you need to reboot into the 3.4 kernel. You do that by selecting Advanced and then selecting the 3.4 kernel in the boot menu of Grub. If it works you need to configure Grub to use that kernel.

I'm just doing this myself, so I may post a follow-up of how to...

Try Set "older" kernel as default grub entry .

EDIT: Try the kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-quantal/ It worked better for me, because I had a problem with sound with my headset with the earlier version.
