+# MacBook Pro 12,1
+
+## Wireless won't get reconnected after resume/hibernate
+
+The wifi driver is unloaded before suspend/hibernate to workaround driver issues.
+This means it might be required to restart your wifi deamon i.e. wpa_supplicant:
+
+```nix
+powerManagement.powerUpCommands = ''
+  ${pkgs.systemd}/bin/systemctl restart wpa_supplicant.service
+'';
+};
+```
+
+You can apply this to your network management software of choice.
