After a system update on 16th Dec 2020 I discovered I had networking problems when I was using WINE. I have determined the issue is NOT WINE but something else in the system. When I do a system downgrade using the Arch Linux Archives for 13th Dec 2020 the networking problems with WINE disappear. System upgrade to 14th Dec 2020 WINE networking problems appear. The only new packages that are upgraded on my system are: egl-wayland-1.1.6-1-x86_64.pkg.tar.zst 14-Dec-2020 11:02 24K gtkmm3-3.24.3-1-x86_64.pkg.tar.zst 14-Dec-2020 00:28 1M python-importlib-metadata-3.3.0-1-any.pkg.tar.z..> 14-Dec-2020 02:46 566 xorg-xwayland-1.20.0.r797.g5d73a8b59-1-x86_64.p..> 14-Dec-2020 12:16 898K The egl-wayland and xorg-xwayland packages do not appear to be causing the problem. The gtkmm3 should not raise this type of issue. Close inspection of the python-importlib-metadata should not cause any issues either. The only possible solution I can possible consider is creating a new partition and installing the Dec 2020 Arch iso then doing a system upgrade to 13th Dec to get a problem free system. I decided to try the list to see if anyone else may have a solution. Regards John
