ubuntu 19.10アップグレード後、Wifiネットワークマネージャーが機能しない

Question

Intel m7800とIntel Wireless 7260を使用しています。

Do-release-upgradeを使用してラップトップをUbuntu 19.04から19.10にアップグレードしたところ、network-managerが機能しなくなりました。 Windowsで起動したり、19.10 Ubuntuインストーラーを使用したりしても、ネットワークカードは問題ありません。

network-managerは非常に短時間接続します。 systrayネットワークアイコンが「...」に接続し（接続されていない）、インターネットが機能し（場合によっては1分程度、場合によってはそれより少なく）、最後にネットワーク接続が失敗したことを示す通知が届き、接続がダウンします。 gnome設定のwifiパネルに「Wifi-Unavailable」または「Unavailable 802.1x supplicant failed」と表示されます

安定したネットワーキングを取得するには、wicdをインストールする必要がありました。

19.04から19.10へのハードワイヤードネットワークカードのアップグレードでも、同じ問題が発生しました。少なくともインターネットを機能させる（ネットワークマネージャは機能させない）ことがわかった解決策は、イーサネットカード用のコマンド「Sudo dhclient enp3s0」を使用することです。 wifiデバイス用の「Sudo dhclient wlp2s0」を試してみてください。お役に立てれば。 2か月間回答がないため、おそらく別の解決策を見つけました。
