I have a D-Link DWA-160 Wireless adapter, and the current driver (carl9170) has some really, really, really frustrating bugs. (Well, just one, but it's a real showstopper.)

Whenever I'm in Puppy Linux, this bug doesn't occur. The difference is, Puppy Linux says it's using ar9170. I'd like to use that for Ubuntu and see if it works better there, as well. I'd like to know the exact procedure for doing this.

The modinfo on the other Linux distribution shows me it's still on Linux 2.6.33. The driver you refer to is removed in recent Linux versions:

ar9170usb: purge obsolete driver



git branch -a --contains b0006e69615868
  remotes/origin/HEAD -> origin/master
  remotes/origin/linux-3.0.y
  remotes/origin/linux-3.1.y
  remotes/origin/linux-3.2.y
  remotes/origin/linux-3.3.y
  remotes/origin/linux-3.4.y
  remotes/origin/linux-3.5.y
  remotes/origin/linux-3.6.y
  remotes/origin/linux-3.7.y
  remotes/origin/master

This indicates to me that ar9170usb was removed from 3.0 onwards. I think it will be hard to get this module into a recent Ubuntu release.

So, taking a step back, getting the newer driver fixed seems a bit more constructive. In case you're on Ubuntu 12.04, try the backported Quantal kernel linux-image-generic-lts-quantal package. If that doesn't fix it or if you're on Quantal already, try a more recent "mainline" kernel to see if your issue is fixed "upstream". This answer explains how to install pre-built mainline kernels in Ubuntu.

Try the suggested workaround in this answer for similar hardware (same chipset). It seems to have fixed it on my system today, also with this DWA-160 adapter. Check it out and see if it helps. I also downloaded the latest firmware file I could find. (version 1.9.7)

I also found major bugs with using the carl9170 driver. If it is anything like mine then it bombed out the internet connection when downloading or even surfing media rich sites.
