I have an XPS 13 9380, 2 months old.
my problem is that when I connect to monitor through type-C adapter and HDMI cable, my wifi disconnects, or sometimes it connects but I have no internet.
I've been connecting to a monitor since I had my laptop, but this problem started lately, and became worse over time.
how can I fix this?
What monitor are you connecting the laptop to? Have you reseated the cables? Have you reset your router? Have you tried other cables? Does the wifi work when not connected to the monitor?
It's connected to PHILIPS E234 monitor,
connected with type C adapter that has 3 ports: 1. HDMI 2. normal USB 3. USB type C.
if I disconnected the monitor, the wifi works perfect.
I heard it's something with the HDMI type C and the frequency of the wifi.
the solution that is working for me is connecting port #2 (normal USB) to a stereo and the aux also, everything is fine after doing that.
