Intel Dual Band Wireless-AC 7260 for Desktop on Linux

I just bought new wifi card for my desktop computer. Like in topic, it’s Intel Dual Band Wireless-AC 7260 for Desktop.

I was searching for card that:

  • support AC standard
  • have 5GHz network support (2,4GHz channels are cluttered heavily in my neighborhood
  • have PCI/PCIx or USB3 connector
  • is Linux friendly (no modules compilation by hand, support for aircrack-ng, kismet)

This one is the only I found that comply my expectations.

I found time to play with `kismet` and `aircrack-ng` and it was working fine. Card works without problems on kernel 4.2.0. Highest transfer on my net I could get from my NAS – about 23 MB/s (megabytes per second) – much better than on my old N router (approx 6,5 MB/s).

Here’s information from lspci -vvv:
