    HP Pavilion 590 with RTL8821CE or RT5392 PCIe doesn't see WiFi

    Hi,
    Recently I've bought an HP Pavilion 590-p0008nl at which I've mounted a NILOX wireless PCI express card [1] because I wasn't able to see my WiFi Network.

    I'm using Ubuntu 18.04 with kernel 5.0.0-31-generic and this is the list of my network hardware:
    Code:
    sudo lshw -C network

    I've tried to install the driver for RTL8821CE following the instructions described at https://github.com/tomaspinho/rtl8821ce and even disabling the SecureBoot I can't use my WiFi [2]. I think that procedure doesn't work properly with kernel 5.*.

    Why I can't use my wireless PCI card? Do you think there is any kind of conflict between drivers?


    [1] I used this PCI card with my previous PC under Ubuntu 16.04.
    [2] The WiFi is seen only for a couple of seconds as soon as I turn on the PC.


    Thanks.

    Installing the driver RTL8821ce from that branch doesn't solve the problem.

    I'm still wondering why an external PCI card is not completely recognised?
    Do you think the problem is just its driver, the RT5392? Maybe I'll try the step *How to update the driver after a Linux kernel upgrade* reported at https://github.com/agerwick/RT28XX-RT539X-Linux-driver

    At the end I've been able to install the driver for RTL8821CE following https://github.com/shubham151/rtl8821ce

    Code:
    git clone https://github.com/shubham151/rtl8821ce.git
    cd rtl8821ce
    sudo make all
    sudo make install
    Then it's neccessary to save the name of the module in /etc/modules. Finally restart.

    Since every now and then I still had some issues with the internet connection, Today I've decided to move from ubuntu 18.04.1 to 18.04.4 and to install https://packages.ubuntu.com/bionic-u...rtl8821ce-dkms, which can be found in Synaptic. The wifi has been recognized immediately!!
