WLAN not stable

The WLAN is sometimes not stable on my system.
I’m not sure if this caused by the WLAN system of my laptop or by AVM FritzOS (inl. MESH).

Device-2: Realtek RTL8822CE 802.11ac PCIe Wireless Network Adapter
    vendor: Lenovo driver: rtw_8822ce v: N/A pcie: speed: 2.5 GT/s lanes: 1
    port: 2000 bus-ID: 03:00.0 chip-ID: 10ec:c822 class-ID: 0280

Sometimes I have interruptions of the connection and no WLAN network is shown in the selection dialog.

Does anyone have expierence with this or similar issues?

Seems to be an issue related to your chipset.


The chipset seems to have wifi and bluetooth on one chip, which is cheaper but therefore more error-prone.
You could also buy a better wifi (usb) for your laptop.

Thanks for the information.
I will give it a closer look the next days.

Did you try following the solution in the first link I gave?

Not yet, I will give it a closer look the next days.
I have to read and understand it, before testing.

I’m still a newbie :wink:

It would perhaps be better to do the installations using your ethernet adapter, instead of the wifi. If that is not an option, you have to use a live ISO to boot, and chroot into the installed system and do the updates/installations of drivers from within the chroot-environment.

I agree, installation is better (safer and more stable) with ethernet… but for “normal” use is WLAN more comfortable
