Hi everyone,
I’m experiencing issues with my wifi adapter when the network manager has been restarted. The wifi connection works without any issues until the service is restarted.
The OS tries to reconnect with the known wifi network, the circle turns in the statusbar and the connection can’t be established.
I’m using following wlan adapter:
02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8821CE 802.11ac PCIe Wireless Network Adapter
This is the output of the systemlog:

Has anybody experienced a same strange behaviour on an idea how to fix the issue?
Currently a reboot is the only solution from my side.
