Wifi Abbrueche und System Crash

[Guiste]

Hi,

ich hab vor kurzem Debian Stretch installiert neben Windows 8 und hab jetzt 2 Probleme:

1. Die wifi Verbindung wird staendig unterbrochen, das nervt insbesondere, wenn man mit ssh verbunden ist und staendig rausgeworfen wird, schaetze das ist mal wieder ein Firmware Problem? Als ich noch Debian Jessie neben Windows installiert hatte, hatte ich das Problem nicht.
2. Ich hatte gerade einen Crash, also der PC ist in irgendeinen Modus gegangen und danach ins Loginmenue hat aber saemtliche Fenster geschlossen, also als wenn er neu gebootet haette. Den Fehler hatte ich davor auch schon, als ich noch Jessie neben Windows installiert hatte.

Ein paar logs und outputs mal hier

Bit Rate=86.7 Mb/s Tx-Power=20 dBm

Link Quality=55/70 Signal level=-55 dBm

55/70 sieht eigentlich gut aus,
8MB/s (trotz firmware iwlwifi-7260-17.ucode) scheint verwunderlich.

Irgendeine Meshing-Technik o.ä.? ZBsp. der (eine) WLAN-Router in einem speziellen "Zweinetz"-Modus?

Vielleicht mal mit den iwlwifi-Optionen spielen?
