Qualcomm Atheros Device [168c:0042] (rev 30) With Ubuntu 14.04 is not working
I bought a Lenovo ideapad 300 laptop and installed Ubuntu 14.04 on it. The laptop's wifi card is Qualcomm Atheros Device [168c:0042] (rev 30).
I don't want to upgrade to 15.04 or 15.10 as I am running software that later will run on 14.04 servers, so I want to keep my development environment as close to run time environment.
I read that Ndiswrapper will not work here - Ndiswrapper won't work
I then found Jeremy31 answer here - install backports
I ran the commands in Jeremy31's answer and rebooted, but I saw no change. After I ran the commands, I dmesg | grep ath10k gave me nothing. sudo modprobe ath10k_pci && dmesg | grep ath results are not relevant:
[ 0.643855] Loaded X.509 cert 'Magrathea: Glacier signing key: e09b1e7e9841e9cfef256b70ab210562dab1ef68'
[ 4855.547585] [<ffffffff81074dea>] warn_slowpath_common+0x8a/0xc0
[ 4855.547587] [<ffffffff81074e66>] warn_slowpath_fmt+0x46/0x50
I'll appreciate some help solving this issue. Thanks in advance
