    Default AW: rtl8821ce wireless

    What I have done:
    Fresh Installation of Tumbleweed, switched from btrfs to ext4 in / to get a fresh formatted disk, /home is the old one.
    No extra driver installed, only conecting by networkmanager with WPA2 passwort:,

    Code:
    hp-laptop:/home/stephan # ping -c5 8.8.8.8

    last night i failed to get it working using dkms or by using ndiswrapper with realteks driver. the problem, i think in both cases, was errors that my kernel headers werent right. so i wasnt able to actually compile ndiswrapper, and ive never had to mess with kernel headers before. your solution seems a lot easier if it will work, but im a little bit cautious because in my case it was never working without using your/variations of your driver(s).

    /sbin/lspci/ -nnk | grep -iA3 net

    Code:
    02:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8821CE 802.11ac PCIe Wireless Network Adapter [10ec:c821]	DeviceName: WLAN
    	Subsystem: AzureWave Device [1a3b:3040]
    	Kernel modules: rtw88_8821ce, rtw_8821ce, wl
    looks like another release to download. ill try that, and try again after removing rtw88, if that doesnt work. if still no working wireless adapter, ill grab the new tumbleweed .iso and report back without installing any other drivers.

    Post:
    Code:
    zypper se -sir sauerland
    That shows all installed packages from my Repo (if it is installed and enabled)
    Also:

    PS:
    sudo is in openSUSE not as working as in Ubuntu.
    Better is to login as root with
    Code:
    su -l
    (su space minus el) to get a loginshell.
