No wireless in Fedora 23

[vinicius]

I have a inspiron 15 5557 which uses a Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter and just installed F23. However I cannot get the wifi to connect. After some research I have found that there appears to be an issue involving my wireless adapter and its firmware, but that this issue has supposedly being resolved. However, for me it just doesn't work. The issue is described here and apparently there is a solution discussed in comment #11 on that thread shown here which implies downloading the firmware from this link. I did all that. First I tried to update the firmware as suggested here and here using both "dnf --enablerepo=updates-testing update linux-firmware" and "dnf update linux-firmware" but no updates were available. After that I try to copy the firmware directly from the link into the folders /lib/firmware/ath10k/QCA6174/hw3.0 and /lib/firmware/ath10k/QCA6174/hw2.1 and restarted the computer as suggested here in "Update Firmware" and again no wireless at all. The output of "dmesg | grep ath10k" is

Thank you all for your help.

[vinicius]

A detail that might be important. I logged in via an Ubuntu 14 LTS live cd and the wireless was also not working.

[Atsuri]

vinicius, do the 'failed to enable...' and 'could not suspend...' messages keep repeating constantly? Also, have you tried powering the NIC down and restarting it? However, it clearly seems that the firmware is not loaded at all, hmm...

Instead of using the testing repo, you could try pulling linux firmware from the bleeding-edge rawhide repo, but that might be risky. Otherwise, I would just file a bug to upstream and wait for a response .

[vinicius]

Thank you Atsuri. I cannot check for some of your suggestions now because I am lost in the middle of the nvidia driver installation and have no X. You suggestion is that I file another error at "bugzilla.redhat.com"? thank you.

[Atsuri]

You can file a bug at Red Hat's Bugzilla or directly contact the upstream responsible for the driver (kernel.org?). I think both are fine, though it's good to let the driver maintainer know .

[vinicius]

I have found the solution on this post here in ArchLinux. Basically what I have done was

1. I have replaced all binary files in both folders /lib/firmware/ath10k/QCA6174/hw2.1/ and /lib/firmware/ath10k/QCA6174/hw3.0/ for the files provided in this link;
2. made all binaries executables doing chmod a+x /lib/firmware/ath10k/QCA6174/hw2.1/* and chmod a+x /lib/firmware/ath10k/QCA6174/hw3.0/*;
3. created the file /etc/modprobe.d/ath10k.conf by doing "echo "options ath10k_core skip_otp=y" > /etc/modprobe.d/ath10k.conf"
4. restarted the computer;

Now both wifi and Bluetooth seems to works fine, although my dmesg output is still not clean

I dont know how relevant this is but my kernel has been updated to a newer version

[vinicius@localhost Desktop]$ uname -r
4.4.2-301.fc23.x86_64

although the problem has only been solved after executing all four steps enlisted above.

[Atsuri]

The error messages in dmesg seem to be unchanged and normally I would say not all warnings are fatal as long as the connection can be maintained and RAM/CPU usage doesn't spike for no clear reason.

Could you please check whether the connection doesn't drop from time to time or overall signal doesn't deteriorates?

I would include such symptoms in an existing bug report or file a new one if those symptoms + dmesg notifications are novel. Also, include the temporary fix you found for Arch Linux!

hi folks!
I've made the steps above and i no have 5GHz wifi. Any ideia? Connections, only on 2.4Ghz.
