The driver requires firmware:

$ modinfo iwlwifi
filename:       /home/chili/Downloads/backports-3.16-1/drivers/net/wireless/iwlwifi/iwlwifi.ko
version:        backported from Linux (v3.16-0-g19583ca) using backports v3.16-1-0-g87df966

firmware:       iwlwifi-7260-9.ucode
firmware:       iwlwifi-8000-8.ucode

If your linux-firmware package is fully updated, you probably have it; check: Code:

$ ls /lib/firmware | grep 7260
iwlwifi-7260-7.ucode
iwlwifi-7260-8.ucode
iwlwifi-7260-9.ucode

The first command shows what firmware the module depends on. There are a number of such firmware

Then why in the second command, only check firmware containing 7260 in filename? What about other firmware?

Does it also list the firmware not used by the module, such as iwlwifi-7260-7.ucode and iwlwifi-7260-8.ucode?

  • Since the title of the forum message you cited was `Ubuntu 14.04 reports no wireless card with Intel Wireless 7260`, it makes sense that an answer for it would be looking only for 7260 firmware. – Mark Plotnick Apr 13 '15 at 20:40
  • @MarkPlotnick Answers should be posted as answers. – derobert Apr 13 '15 at 20:41
  • @Mark: Thanks. How can I check if all the firmware needed by `iwlwifi` are installed, instead of checking one by one by second command? – Tim Apr 13 '15 at 20:45
  • @Tim I don't know the answer to that part of your question. – Mark Plotnick Apr 13 '15 at 20:48
  • @Mark: to check if a firmware is installed, is the same to find if there is a file with the name under `/lib/firmware`? – Tim Apr 13 '15 at 20:48
  • @Tim I don't know. If you grep for `firmware` in `/var/log/syslog`, do you see any lines referring to iwlwifi firmware being requested and successfully loaded? – Mark Plotnick Apr 13 '15 at 20:56
