What was the last working kernel version? Can you attach the output of dmesg from both a working kernel and 3.13.10? It was the same result on the prior kernel. I bought the laptop last week so for me it has never worked. Following workaround works: 1: Boot up Fedora 20 (The wireless dont work due to killswitch) 2: Unload all ath9k kernelmodules with rmmod: ath9k 150307 0 ath9k_common 13258 1 ath9k ath9k_hw 448149 2 ath9k_common,ath9k 3: Close the lid on the laptop, wait a minute. 4: Open the lid and do modprobe ath9k and the wifi comes alive.

dmesg
Try with these three WAPF values, adding them to the kernel command line: 1. asus-nb-wmi.wapf=0 2. asus-nb-wmi.wapf=1 3. asus-nb-wmi.wapf=4 Which of them enables WLAN device for the X550CA? e.g. asus-nb-wmi: set wapf=4 for ASUSTeK COMPUTER INC. X75VBP http://marc.info/?l=linux-kernel&m=139819918125110 Soon I'll resend a properly formatted patch to linux-kernel.org. Andreas, if it work and if you are for it, I can append X550CA to a patch. Thereafter we can ask Josh and Stanislaw to urgently apply this to the all Fedora kernels. Wonderful news, good work poma! I confirm that this is a good patch for the Asus X550C. The asus-nb-wmi.wapf=4 added to the kernel on boottime activates the wifi automaticly and it works like a charm. Once again, thanks! and good work. Let me know if you need more tests or feedback from me to be able to commit this patch. Andreas, thanks for testing. The patch has been sent, so let's be patient until someone applies it. Here you can follow the course of events, https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/log/drivers/platform/x86/asus-nb-wmi.c Created attachment 892751 [details]
Set wapf to 4 for ASUSTeK COMPUTER INC. X75VBP & X550CA, so that the wireless network adapter is enabled.
Andreas, can you make a patch for your laptop(X550CA) or I will create it for you? Afterwards you can send it to 'platform-driver-x86.org'. Im sorry i have no C or C++ (kernel programming) skills so i cant provide the patch by myself. So please create it if you are able or instruct me how to provide it.

'WAPF 4 for ASUSTeK COMPUTER INC. X550CA WLAN ON' patch for Andreas
Download "0001-WAPF-4-for-ASUSTeK-COMPUTER-INC.-X550CA-WLAN-ON.patch", attach it to an e-mail and send it to 'platform-driver-x86.org' mailing list.
There already exists a thread "[PATCH] asus-nb-wmi: set wapf=4 for ASUSTeK COMPUTER INC. X75VBP & X550CA", so you only need to replay.
BTW, this patch is far from something really complex like kernel hacking. :)

I have found out that suspending and resuming the machine helps wifi works then. Patch for this bug is applied in 3.16:

asus-wmi: Set WAPF to 4 for Asus X550CA
If you still have problem on kernel newer than 3.16, you probably hit different issue.
Should I create a new bug report for the model Asus X550VB X0016 where wifi only works after suspend+resume otherwise it reports "disabled by radio switch" even with kernel 3.16.3-200.fc20.x86_64? If it can be handle by waps quirk, you do not need to open a new bug report. Does asus-nb-wmi.wapf=4 kernel boot parameter helps ? (In reply to Stanislaw Gruszka from comment #22) > If it can be handle by waps quirk, you do not need to open a new bug report. > Does asus-nb-wmi.wapf=4 kernel boot parameter helps ? Yes, I can confirm adding this boot parameter fixes the issue even on Asus X550VB X0016. Thanks! (no additional info needed) Below test kernel include patch that set wapf=4 by default when X550VB is detected. Please test it without the boot parameter to confirm patch is correct. http://koji.fedoraproject.org/koji/taskinfo?taskID=7820797 (In reply to Stanislaw Gruszka from comment #24) > Below test kernel include patch that set wapf=4 by default when X550VB is > detected.

I'm not the owner of the affected laptop and the owner is a Linux beginner so I'm think about the easiest way how to instruct him to try the kernel above. It's quite simple, just download package for proper architecture (x86_64 or i686) and install it as root by "rpm -i" command. (In reply to Stanislaw Gruszka from comment #26) > It's quite simple, just download package for proper architecture (x86_64 or > i686) and install it as root by "rpm -i" command. Well, I know that, 'yum localinstall' would probably work even better, but aren't multiple packages needed? kernel-modules, etc.? kernel-firmware maybe can be a dependency, but it can be ignored (rpm --force --nodeps) (In reply to Stanislaw Gruszka from comment #24) > Below test kernel include patch that set wapf=4 by default when X550VB is > detected.
