On my Lenovo laptop the Debian 11 works perfectly. Once it was upgraded to the 12 the networking stopped. What happens is it seems like every networking applications gets caught into an infinite loop. For example, using ping it just sits there. The upgrade on the desktop went perfectly. After doing some research, I found the resolv.conf file is now a symlink to a file that does not exist.
This is the information from lshw before the upgrade.
