I am having trouble getting the 8260 card to work with Ubuntu 16.04. I have 2 computers running kernel 4.13.0.38. One computer can connect to my wireless network, and the other cannot.
On the malfunctioning computer - the network interface is up according to ifconfig:
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host

The chipset is an Intel 8260 which appears to have many problems in Ubuntu. According to lshw, firmware v31 is loading:

I have restarted the iwlwifi using modprobe:
sudo modprobe -r iwlwifi
sudo modprobe iwlwifi
I can see wireless networks, but I cannot connect to them. I have duplicated the network settings on the functioning computer, but to no avail. I have also copied the firmware ucode from /lib/firmware, and this also did not work.
Any ideas on how to perform a "diff" between the two computers?

The problem was resolved by setting the regulatory domain on my computers and reflashing my router with country specific firmware. I noticed that I could set my regulatory domain and connect to the router, but once I pinged a device on the network, my regulatory domain would revert to global (00).
I started with the standard discussion of setting the reg domain. I had some problems using crda to set the regulatory domain, so I added options to the cfg80211 module, as other users have done. To make these changes permanent, I had to create the file /etc/modprobe.d/cfg80211.conf and add the following:
options cfg80211 ieee80211_regdom=US
Anyone searching for a diff tool to compare network configurations should use this script.
