一時停止後にWiFiに接続できない
サスペンドから再開した後、Network ManagerはWiFi信号を検出しますが、それに接続しようとすると断念します。
これらの修正は機能しませんでした：
$ Sudo restart network-manager
$ Sudo nmcli nm sleep false
$ Sudo bash -c 'echo SUSPEND_MODULES=\"iwlwifi\" > /etc/pm/config.d/config'
以下は、3つの状況でのdmesg | tail -30の出力です。
ラップトップの電源を入れると、WiFiが接続され動作します。

以下のコマンドを試して、ネットワークマネージャーを再起動します。
Sudo service dbus restart
Sudo service network-manager restart
私はプログラミングについては知りませんが、この問題があり、それを機能させるには、利用可能なときにこのネットワークに自動的に接続するボックスをオフにし、すべてのユーザーがこのネットワークボックスに接続できるようにするをチェックする必要がありました接続->接続の編集->一般
Wi-Fiファームウェアに問題がある可能性があります。これが answer に似た質問への助けになるかもしれません：
Linuxファームウェアgitリポジトリからbrcmfmac43602ファームウェアをダウンロードします
/ lib/firmware/brcmにコピーします
再起動してWiFiをお楽しみください。
MacBook Pro 12,1で試してみたところ、この問題（およびWPA2ネットワークの問題）の解決に役立ちました。
