I have installed the v4.18.rc8-generic kernel (uname: 4.18.0-041800rc8-generic) Unfortunately the problem remains. Although the driver reports itself as the exact same version as in the Ubuntu kernel (info: MWIFIEX VERSION: mwifiex 1.0 (15.68.7.p154) it produced a slightly different dmesg output which might be of help here. I do not know how to set tags here, I would ask you to set 'kernel-bug-exists-upstream'.

After a varying amount of time the wifi connection is gone. The driver does not seem to respond anymore to any action invoked by the gnome ui. My only known workaround for this is to reboot. In this state the shutdown process may take several minutes.
