Hello everyone,

since I switched from ubuntu 19.04 to ubuntu 19.10, I can no longer connect to the 2.4 GHz WLAN of my TL-WPA8630P Powerline adapter. Here is my hardware information:
 

•     Network controller: Intel Corporation Wireless 7260 (rev bb)
•     Powerline adapter: TL-WPA8630P which is connected to a
•     Fritzbox: FRITZ! Box 6490 Cable (lgi)

A Windows 10, an ubuntu 19.04 and the ubuntu 19.10 are running on my computer.

The connection works under Windows and ubuntu 19.04.

With Ubuntu 19.10 the password is requested again after a connection attempt (approx. 15 to 20 seconds).

I can connect to the WiFi of the Fritzbox, I can connect to the 5GHz WiFi of the TL-WPA8630P. But the connection with the 2.4 GHz WLAN of the TL-WPA8630P does not work. If I start the ubuntu 19.10 from an installation stick, I can not establish a connection with the 2.4 GHz WLAN.

Does anyone have any idea what else I could try?

Thank you for thinking along. Greeting,

Mathias
