Wifi is not working on Xubuntu 15.10. I have tried two different cards (build in (Qualcomm Atheros QCA6174 802.11ac) and external usb card (Netgear A6210). The official troubleshooting guide does not work step one (nm-tools: command not found). I have installed drivers according to corresponding instructions, but that didn't help any.

Please see the output of iwconfig, uname -a, route -n, lspci -nnk: http://pastebin.com/aDcYCanu

The output of lspci -nn, dmsg, rfkill list all: http://pastebin.com/z6w27ECM

I tried to follow advice in kind of similar threads. I've spent two weeks, several times recovered OS from Clonezilla image. So, please don't mark this is a duplicate.

Thank you in advance, Stepan

  • Above is with # blacklist bcm43xx. I will post the output when bcm43xx is blacklisted.

  • bcm43xx has nothing to do with either of your devices. Is ndiswrapper an attempt to get the N1525 internal wireless working? Is the usual native linux driver ath10k_pci blacklisted? I was expecting to see that it is missing firmware so that we could download and install it. Any clues here? dmesg | grep firm?

I believe ndiswrapper will be ineffective as I suspect there are no Windows XP driver files available for your device. Let's erase the installation:

sudo ndiswrapper -e netathr7x
sudo rm /etc/ndiswrapper/*

Next, the driver ath10k_pci doesn't appear to load automatically. Please check to see if it is blacklisted:

gksudo gedit /etc/modprobe.d/blacklist.conf

If it is listed as blacklisted, remove the listing, proofread, save and close the text editor.

Next, we see that you lack the needed firmware:

ath10k_pci 0000:03:00.0: Direct firmware load for ath10k/QCA6174/hw2.1/board.bin failed with error -2

I suggest that you do:

sudo mkdir /lib/firmware/ath10k/QCA6174/hw2.1
cd /lib/firmware/ath10k/QCA6174/hw2.1
sudo wget https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/plain/ath10k/QCA6174/hw2.1/firmware-5.bin
sudo wget https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/plain/ath10k/QCA6174/hw2.1/board.bin

Reboot. Let us see another paste of dmesg | grep ath10.

I can finaly reliably enable/disable wireless with just fn+F2 key. I can even connect to iphone hotspot and unencrypted wireless networks. I can't connect to encrypted network of my home router, but this is a different story (I will post it on AskUbuntu). It is puzzling that I don't know what exactly helped. It seems like disabling ndiswrapper + downloading board.bin and firmware-5.bin did the trick. It would be nice to hear chili555's view on this. Thank you for your help, Chili555. Cheers, Stepan
