Ich bekomme keine Verbindung mit meinem 5GHz WLan zustande. Mit der 2,4GHz SSID verbindet sich mein Notebook dagegen ohne Probleme.
Hardware Thinkpad X250 mit Intel 9260 Wifi.
Debian Stretch mit Kernel und intel-firmware aus den Backports (das Problem bestand aber schon mit der Intel 7260 ohne Software aus den Backports)
5GHz WLan funktioniert unter Windows und Ubuntu.
IPv6 habe ich am Router mal deaktiviert: keine Wirkung.
Verschiedene 5GHz Kanäle am Router probiert: keine Wirkung.
Auch ohne Verschlüsselung keine Verbindung.

und Verbindungsversuch in dmesg
