Details

Description:
On wine 6.1-1 (x86_64), network connectivity inside Wine stopped working.
Applications such as WinSCP, Navicat, etc. stopped being able to connect to any network devices, updates didn't work, etc.

Setting "setcap cap_net_raw+epi /usr/bin/wine-preloader" resolved the issue for me.
I'm assuming this used to be a default previously?

Steps to reproduce:
tobias@tobias-arch-laptop ~ % sudo pacman -S wine
tobias@tobias-arch-laptop ~ % wine cmd
Microsoft Windows 6.1.7601

Z:\home\tobias>ping 8.8.8.8

Z:\home\tobias>ping google.de

AFAICT wine-preloader never had the capability bit set. The 6.1 changelog [1] does mention a few network related changes, but nothing which should require the extra cap.
Might be good idea to do a bisection [2] to find the regression and report the findings upstream.

Both wine 7.4 and 7.5 work as expected over here.

Since wine does not require any capabilities, there might be some network-related magic on your end. I would suggest opening a bug upstream - they know the exact workings better than us.
