# 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.
