How To Get Rid Of Statusbar Notification: "no Internet Connection"

[Wemkon]

Hi,

I post this question here again, since in the ROM-thread it will be overseen.

After I updated my Kate from MIUI 8 to 9 I often get the notification "No internet connection", see image attached. Mostly it occurs after waking the device up.

I use AFWall+ firewall. How can I get rid of this notification?

Thanks.
