I am currently facing issues after installing Windows 11 into a VM. When I try to navigate to websites with both Firefox and Edge, or when a applications tries to establish a connection to a remote server, in about 2/3 cases the connection fails. In the browser I get the usual
unable to connect messages from both browser and the applications complain that they can not connect or need very long to run before they timeout.
I am currently cicumventing the issue by spamming reconnect and rerunning the tasks. Every second or third try works. First I thought it has to do with the drivers for the virtio network interface, but then I passed through a wireless dongle and still the same issue occurs.
Network settings as well as the Troubleshooting option can not find anything wrong. Even though no other devices on the network have connectivity issues I tried to change the settings in Windows to use Google DNS. Also does not help.
I am thankful for any useful advice!
