Wifi dropping when connecting to a Dell monitor I have got a Mac Book Pro (13-inch 2020) running macOS Catalina, and the WiFi keeps dropping when connecting to a Dell monitor (DELL P2720D). I'm using a USB C to HDMI Cable https://www.amazon.co.uk/gp/product/B07CL2RHX5/ to connect the Mac to the monitor. I'm not entirely sure where the issue lies. I would really appreciate it if some one could shed some light on this and possibly a solution.

Wifi connection is gone when I plug my mac into the monitor I use Mac M1 2020 with Ventura 13.4 OS. Everytime I plug my mac to monitor using my connector, suddenly my internet gone. It's really painful, I can present my project to my team mate during the meeting with the team. How come this possible with expensive product like mac? Any solution?

Problems connecting M1 Mac mini to wifi WHILE USB-C to HDMI adapter is plugged in Brand new M1 Mac Mini (OS 11.2.2) Home wi-fi connection is unstable and disconnects when a secondary monitor is connected to one of the mac mini USB-C inputs using a HDMI to USB-C adapter (J5Create is the brand of the adapter)https://en.j5create.com/collections/usb-type-c-display-adapters/products/jca153g As soon as I unplug the USB-C adapter to the secondary monitor, the wi-fi connection works with no problem (this is verified through speed tests and the fact that I can come to this website and type this when the monitor is unplugged from the Mac Mini). Primary monitor is connected via the mac mini's HDMI input. Tried wrapping the J5Create adapter in aluminum foil and metallic contact paper to act as a shield; neither help. Any suggestions on how to fix this, or if there even is a fix? Thanks much!

Try a different cable, try a different hub to eliminate interference as a test.
