I'm asking for some feedback from people using the Intel Ultimate-N 6300 wifi card, which uses the iwlwifi kernel module. My experience with this module has been, less than pleasant.
In 2011, I built a laptop with this wireless card, and though I did not know it at the time, it was causing random kernel lockups. (The laptop also had Nvidia Optimus graphics, which I had attributed to the lockups). This was with Ubuntu 11.04, shortly after it came out, not sure what version of iwlwifi it had.
Now, I'm running the same wifi card in a different laptop, on Fedora 17 presently. I'm experiencing the same random lockups as before.
I didn't find the grass greener with Fedora, so I'm migrating back to Ubuntu shortly, and I'd like to hear from people running the aforementioned card: has there been any improvement in the driver as of 12.10? How about in 13.04 testing?
