I have solved this issue after finding this page: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi/core_release Thank you for your documentation. It is very friendly and easy to read. If I may, I suggest that you please point https://wireless.wiki.kernel.org/en/users/Drivers/iwlwifi to the core_release page in some equally friendly way. Thanks again, and keep up the great work .

And while I can see both cards, only the top card (in the physical location) is actually getting assigned the logical (interface) name. This seems to be interment (though I've only had this computer running for two days) because there has been at least one occasion that I have seen both cards assigned an interface name at the same time (via ifconfig and NM). However, when I've had to restart the computer, the names are not always assigned for the 2nd (bottom) card -this is the case most of the time. Attached is the dmesg for the case where I was able to get both cards to work (dm.txt) and the case where I am not able to get both cards to work (dmbad.txt) I've switched out the cards (with other 7260 cards), move the cards to other locations, exchanged the locations of the cards, BUT only the top most device is ever assigned the an interface name. I'm running: 4.7.0-040700-generic GNU/Linux Ubuntu 16.04.1 LTS The two cards are the same Intel Corporation Wireless 7260: # cat /sys/bus/pci/devices/0000\:01\:00.0/uevent DRIVER=iwlwifi PCI_CLASS=28000 PCI_ID=8086:08B1 PCI_SUBSYS_ID=8086:4070 PCI_SLOT_NAME=0000:01:00.0 MODALIAS=pci:v00008086d000008B1sv00008086sd00004070bc02sc80i00 # cat /sys/bus/pci/devices/0000\:02\:00.0/uevent DRIVER=iwlwifi PCI_CLASS=28000 PCI_ID=8086:08B1 PCI_SUBSYS_ID=8086:4070 PCI_SLOT_NAME=0000:02:00.0 MODALIAS=pci:v00008086d000008B1sv00008086sd00004070bc02sc80i00 Only one of the devices is getting assigned a logical name: #sudo lshw -class network .... *-network description: Wireless interface product: Wireless 7260 vendor: Intel Corporation physical id: 0 bus info: pci@0000:01:00.0 logical name: wlp1s0 version: 73 serial: 7c:5c:f8:d2:6c:52 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=iwlwifi driverversion=4.7.0-040700-generic firmware=16.242414.0 latency=0 link=no multicast=yes wireless=IEEE 802.11 resources: irq:32 memory:f7d00000-f7d01fff *-network description: Network controller product: Wireless 7260 vendor: Intel Corporation physical id: 0 bus info: pci@0000:02:00.0 version: 73 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: driver=iwlwifi latency=0 resources: irq:33 memory:f7c00000-f7c01fff dmesg does not show that the 2nd device on bus 0000:02:00.0 has been detected by the wifi driver {Attached as dmbad.txt} and ifconfig only shows one device (obviously since lshw showed that only one was getting assigned a logical name) #ifconfig ... wlp1s0 Link encap:Ethernet HWaddr 7c:5c:f8:d2:6c:52 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) #ls /lib/firmware | grep 7260 iwlwifi-7260-10.ucode iwlwifi-7260-12.ucode iwlwifi-7260-13.ucode iwlwifi-7260-14.ucode iwlwifi-7260-16.ucode iwlwifi-7260-7.ucode iwlwifi-7260-8.ucode iwlwifi-7260-9.ucode #modinfo iwlwifi filename: /lib/modules/4.7.0-040700-generic/kernel/drivers/net/wireless/intel/iwlwifi/iwlwifi.ko license: GPL author: Copyright(c) 2003- 2015 Intel Corporation <[email protected]> description: Intel(R) Wireless WiFi driver for Linux firmware: iwlwifi-100-5.ucode firmware: iwlwifi-1000-5.ucode firmware: iwlwifi-135-6.ucode firmware: iwlwifi-105-6.ucode firmware: iwlwifi-2030-6.ucode firmware: iwlwifi-2000-6.ucode firmware: iwlwifi-5150-2.ucode firmware: iwlwifi-5000-5.ucode firmware: iwlwifi-6000g2b-IWL6000G2B_UCODE_API_MAX.ucode firmware: iwlwifi-6000g2a-6.ucode firmware: iwlwifi-6050-5.ucode firmware: iwlwifi-6000-6.ucode firmware: iwlwifi-7265D-21.ucode firmware: iwlwifi-7265-17.ucode firmware: iwlwifi-3168-21.ucode firmware: iwlwifi-3160-17.ucode firmware: iwlwifi-7260-17.ucode firmware: iwlwifi-8265-21.ucode firmware: iwlwifi-8000C--21.ucode firmware: iwlwifi-9260-th-a0-lc-a0--21.ucode firmware: iwlwifi-9260-th-a0-jf-a0--21.ucode firmware: iwlwifi-9000-pu-a0-lc-a0--21.ucode alias: pci:v00008086d00009DF0sv*sd00002A10bc*sc*i* alias: pci:v00008086d00009DF0sv*sd00000710bc*sc*i* .... depends: cfg80211 intree: Y vermagic: 4.7.0-040700-generic SMP mod_unload modversions parm: swcrypto:using crypto in software (default 0 [hardware]) (int) parm: 11n_disable:disable 11n functionality, bitmap: 1: full, 2: disable agg TX, 4: disable agg RX, 8 enable agg TX (uint) parm: amsdu_size:amsdu size 0:4K 1:8K 2:12K (default 0) (int) parm: fw_restart:restart firmware in case of error (default true) (bool) parm: antenna_coupling:specify antenna coupling in dB (default: 0 dB) (int) parm: nvm_file:NVM file name (charp) parm: d0i3_disable:disable d0i3 functionality (default: Y) (bool) parm: lar_disable:disable LAR functionality (default: N) (bool) parm: uapsd_disable:disable U-APSD functionality bitmap 1: BSS 2: P2P Client (default: 3) (uint) parm: bt_coex_active:enable wifi/bt co-exist (default: enable) (bool) parm: led_mode:0=system default, 1=On(RF On)/Off(RF Off), 2=blinking, 3=Off (default: 0) (int) parm: power_save:enable WiFi power management (default: disable) (bool) parm: power_level:default power save level (range from 1 - 5, default: 1) (int) parm: fw_monitor:firmware monitor - to debug FW (default: false - needs lots of memory) (bool) parm: d0i3_timeout:Timeout to D0i3 entry when idle (ms) (uint) parm: disable_11ac:Disable VHT capabilities (default: false) (bool) Please let me know if there's anything I can do or if this is a known issue.
