    Problem with wifi on new laptop

    The specs of the wifi with this laptop are (i.e. The Chipset):

    Vendor & Model
    Foxconn T77H456.20
    1x1 BGN + BT 4.0
    Foxconn T77H525.03 NFA335
    1x1 BGN + BT 4.0

    Chipset Broadcom BCM43142 Qualcomm Atheros QCA9565
    Form factor Half-Mini Card
    Frequency band 2.4 GHz
    Protocols and
    data rates
    supported
    BT:
    1 Mbps, 2 Mbps, 3 Mbps for EDR
    Wi-Fi:
    802.11b - 1-11 Mbps
    802.11g - 6-54 Mbps
    802.11n - MCS 0 to 7 for HT20 MHz and HT40 MHz
    Antennae Yes. Both AUX and MAIN are routed in the display assembly.
    Feature ? Support for BT & WLAN Co-existence
    RoHS Compliance
    Low Halogen Compliance

    The problem with this is that while the card looks like it was added via ifconfig on install, it wasn't configured. It remains unclear to me how to configure it when theres no "add wifi button" in the fault gui of Fedora22. I would appreciate any help anyone could give me.

    From ifconfig:

    I have no idea how to configure this on fedora manually as I'm new to Fedora.

    Re: Problem with wifi on new laptop

    ifconfig 'works' but has been deprecated for years. ip link is a better choice.
    Your ifconfig output is showing your wired enet (the realtek part)

    You generally don't want to manually configure wifi, but will want to use NetworkManager.

    --

    Your wifi part is Qualcomm Atheros QCA9377 (not Broadcom), and is very new and not supported with a Linux driver (afaict). Your device should have a PCI ids 168c:0042 and you should see that in the lspci -nnk output.

    The 'wl' driver is for Broadcom and will certainly not work on your Qualcomm part.
    If it's really claiming the device (see lspci -nnk driver and/or the dmesg output) this will interfere with any correct driver.

    I expect that your part will get driver support (perhaps via the ath9k driver) at some time in the future. Until then these are your options.

    Try ndiswrapper (wraps the Win driver) but I haven't used this in years.
    or
    buy a USB wireless to use for several months.

    Re: Problem with wifi on new laptop

    Can I ask a followup question then?

    I have a usb dongle but, it keeps crashing. I was wondering what would be causing this. Also I was wondering why my touchpad on this laptop keeps crashing also and sometimes doesn't immediately become available when I boot up. Tyvm in advance.

    "Bus 001 Device 002: ID 7392:7811 Edimax Technology Co., Ltd EW-7811Un 802.11n Wireless Adapter [Realtek RTL8188CUS]"

    Also I have windows drivers for the card in .inf format. I'm having trouble setting it up though. The Atheros one. I was wondering if you had any walk-throughs available.

    Re: Problem with wifi on new laptop

    Oh dear, you really are having bad luck with adaptors. That usb realtek 8188cus chip is supported by the kernels but the modules are very buggy and pretty much useless. There is a fix being worked on which will be submitted to the kernel developers shortly and that 'should' be cross distribution. I am only aware of the ubuntu/mint patches on github at present though.

    Re: Problem with wifi on new laptop

    Do you think the driver will be updated automatically in the next week or ...<insert time here> ?

    Re: Problem with wifi on new laptop

    Your guess is as good as mine. The patch is written by a knowledgeable user who is submitting it to the Kernel Developers for inclusion. How long that process will take if it even gets approved I honestly couldn't tell you.

    Re: Problem with wifi on new laptop

    The QCA9377 appears to be more similar to the ath10k driver parts. Atheros generally writes the Linux kernel drivers for their parts, but it's hard to predict when they will get around to it. I don't see any recetn coments on the ath10k and ath9k driver maillists.

    Re: Problem with wifi on new laptop

    The QCA9377 is now working via a patched ath10k module provided by kvolo_at_qca.qualcomm_dot com. The backports have been made as well.

    Here's what I did to get it working under Ubuntu:

    Code:
    sudo apt-get install build-essential linux-headers-$(uname -r) git
    echo "options ath10k_core skip_otp=y" | sudo tee /etc/modprobe.d/ath10k_core.conf
    wget http://filebin.ca/2LVgpjSgiT56/backp...-11-05.tar.bz2
    unzip backp...-11-05.tar.bz2
    cd backports-ath10k-2015-11-05
    make defconfig-ath10k
    make
    sudo make install
    git clone https://github.com/kvalo/ath10k-firmware.git
    sudo cp -r ath10k-firmware/ath10k/ /lib/firmware/
    sudo cp -r ath10k-firmware/QCA9377 /lib/firmware/ath10k/
    cp firmware-5.bin_WLAN.TF.1.0-00267-1 firmware-5.bin
    Reboot
    Problem is, I can't get it to work in Fedora (Yes, I've replaced 'apt-get' with dnf, "build-essentia" with the similar packages from fedora) and 'linux-headers' with kernel-headers. I can't get the backport to compile, as it says:

    Code:
    [whizkidraj@localhost ~]$ sudo dnf install make automake gcc gcc-c++ kernel-devel kernel-headers-$(uname -r) git

    Re: Problem with wifi on new laptop

    The following got the QCA9377 Qualcomm Atheros Device [168c:0042] working under Fedora 23:

    Code:
    sudo dnf install kernel-devel-$(uname -r) make automake gcc gcc-c++ git
    echo "options ath10k_core skip_otp=y" | sudo tee /etc/modprobe.d/ath10k_core.conf

    tar -vxf backports-ath-2015-11-05.tar.bz2
    cd backports-ath-2015-11-05
    make defconfig-ath10k
    make
    sudo make install
    git clone https://github.com/kvalo/ath10k-firmware.git
    sudo cp -r ath10k-firmware/ath10k/ /lib/firmware/

    Re: Problem with wifi on new laptop

    The link in the wget command is broken

    wget http://filebin.ca/2LVgpjSgiT56/backp...-11-05.tar.bz2

    Could you please upload it again?

    Thanks

    Re: Problem with wifi on new laptop

    Try this link

    wget https://www.kernel.org/pub/linux/ker...0151120.tar.gz

    The package there works ... probably a newer version. I ran the commands as suggested two posts above just now and my wireless is on after a reboot.
