Lenovo Zhaoyang e42-80 Qualcomm QCA9377 installation Ubuntu14.04 cannot use Wi-Fi solution

Lenovo Zhaoyang E42-80 Notebook uses the Wi-Fi QCA9377, and the latest Ubuntu 14.04 system kernel uses 4.4, the kernel online a lot of information on the QCA9377 support problems, 4.5 kernel has been perfect support.

Follow the method given by Lenovo Zhaoyang k20-80 installation Solution (http://blog.csdn.net/ssy_neo/article/details/51786044) that is not available for Ubuntu Wi-Fi, upgrade the kernel first and then go to HTTPS ://github.com/kvalo/ath10k-firmware/archive/master.zip get QCA9377 bin, put to the corresponding/lib/firmware/ath10k/qca9377/hw1.0/ Still does not work, DMESG still the error is as follows, possibly because two notebook uses Wi-Fi chip to have the slight difference result:

ATH10K_PCI 0000:02:00.0:direct firmware load Forath10k/cal-pci-0000:02:00.0.bin failed with error-2

Finally in the Arch Linux saw a Acer R11 also encountered the same problem, and then the clues to the Lenovo E42-80 notebook Wi-Fi problem to solve.

The problem is as follows:

First, view the status of the module

sudo rfkill list all can see the status of WLAN hard blocked is yes, note that there is no online said 3:phy0

0:ideapad_wlan:wireless LAN

Softblocked:no

Hardblocked:yes

1:ideapad_bluetooth:bluetooth

Softblocked:yes

Hardblocked:yes

2:hci0:bluetooth

Softblocked:yes

Hardblocked:no

Second, DMESG | grep ath10k See some firmware that are missing QCA9377.

ATH10K_PCI 0000:03:00.0:direct firmware load Forath10k/cal-pci-0000:03:00.0.bin failed with error-2

ATH10K_PCI 0000:03:00.0:direct firmware load Forath10k/qca9377/hw1.0/board.bin failed with error-2

The workaround is as follows:

1, to Https://github.com/kvalo/ath10k-firmware/archive/master.zip get QCA9377 bin, put to the corresponding/lib/firmware/ath10k/qca9377/ hw1.0/, at this point the sudo rfkill list all is still a WLAN hard blocked is yes and does not have 3:phy0

And to view DMESG still has failed:

ATH10K_PCI 0000:03:00.0:direct firmware load Forath10k/cal-pci-0000:03:00.0.bin failed with error-2

2. According to the WiFi issues with Acer R11 (ath10k/qca9377chip) (https://bbs.archlinux.org/viewtopic.php?id=211280) in Arch Linux, To Https://github.com/ajaybhatia/Qualcomm-Atheros-QCA9377-Wifi-Linux Next Qualcomm-atheros-qca9377-wifi-linux-master.zip and then unpack.

3, into the extracted directory, there are two ways, one is the Arch Linux./install.sh directly update the compiled firmware to the corresponding location, not for the Ubuntu system, the other is the way to compile the firmware./install_for_ kernel_4.4-rc2.sh

Note: Directly run the pace of compiling, configuration This step is likely to fail, I was a failure, need to compile step-by-step. After compiling, Makeinstall.

4, after install, restart the computer, but Wi-Fi function is still not good, fortunately, in the upper right corner can see Wi-Fi out, although the display wireless is disabled by hardware switch. Rfkill List all can also see the 3:phy0.

x@x:~$ Rfkill List all

0:ideapad_wlan:wireless LAN

Softblocked:no

Hardblocked:yes

1:ideapad_bluetooth:bluetooth

Softblocked:yes

Hardblocked:yes

2:hci0:bluetooth

Softblocked:yes

Hardblocked:no

3:phy0:wireless LAN

Softblocked:no

Hardblocked:no

5, this reason is because the associative module ideapad_laptop to the hardware is prohibited, after unloading the module, WiFi is normal.

sudo modprobe-r ideapad_laptop

$ ifconfig Wlan0

Wlan0 Link encap:ethernet hwaddrf8:28:19:c8:93:7b

6, after reboot, still have ideapad_laptop, so need to add it to the blacklist can.

To create a new ideapad.conf in/etc/modprobe.d/, the file reads as follows:

Blacklist ideapad_laptop
