I'm not saying this is yet another stupid function of the Logitech Harmony 900, but it turns out while it's connected, it breaks Windows Subsystem for Linux.
for some reason the fact it appears as a network device causes WSL to try to route all packets over it, which doesn't work
and yes, I know github is having trouble right now: but this is not related.
all DNS requests fail, all TCP connections fail... except to those going to the remote.
This is probably why the control software keeps telling you to connect the remote when it's about to download new settings... they don't expect you to keep it connected for longer than it takes to update, because it breaks your everything.
the weird thing is that plain windows stuff works fine. It's only the WSL that is failing.
So there must be some difference in how WSL-based networking is done compared to normal windows
