Dell XPS 9550 wifiの問題

低速と低信号が最も明らかないくつかのタイプの問題が発生しています。さらにまれに、切断されるか、wifi-managerがワイヤレスキーを要求し続けます（ただし、正しいキーを入力しています）。また、一時停止後、network-managerにネットワークがなくなり、すべての選択がグレー表示されます。

また、dmesgには以下がたくさんあります。
brcmf_cfg80211_reg_notifier: not a ISO3166 code (0x30 0x30)
そして
brcmf_inetaddr_changed: fail to get arp ip table err:-23

私の問題を解決する方法を研究するのに多くの時間を費やした後、私は最良の解決策がインテルのカードで私のワイヤレスカードを変えることであることに気づきました。
この方法で、ワイヤレスネットワークの問題だけでなく、Bluetoothの問題も解決しました。

この答えは私が期待していたものではなかったことを知っていますが、もしそれを知っていれば、ずっと前に20ドルと2分を費やして変更していたでしょう。

そのため、Dell XPS 9550のWi-Fiに問題がある人への私のアドバイスは、Wi-Fiカードを変更することです（Intel Wireless Dual Band AC 8260NGW 867Mbps WIFI Card Bluetooth 4.2 8265NGWを使用しました）。

また、@ chili555に感謝します。
