私TP-LinkAV-500電源コードアダプタキットは、家の中の1つにワイヤレスAPを提供します。電源コードを介してプライマリルータに接続されます。しかし、私のラップトップは64ビットArch Linuxを実行していますが、接続できません。
他のデバイス（Android携帯、iPhone、Androidタブレット）は問題なく接続されています。ラップトップはルーターや他のアクセスポイント（5GHzネットワークを含む）に完全に接続されていますが、TP-Linkアクセスポイントは表示されますが、接続することはできません。関連部分は次のとおりですdmesg。

私もwlドライバーを試してみました。
$ sudo modprobe -r brcmsmac
$ sudo modprobe wl
$ sudo modprobe lib80211
これも接続に失敗しますが、他のエラーが発生します。

ipv6.disable=1GAD3Rの提案に従って行optionsを追加し、/boot/loader/entries/arch.confIPv6行をコメントアウトし、再起動して/etc/hostsIPv6を無効にしてみました。変わりません。
