Haha right,thats quite simple,should have seen you meant this. Unfortunately mine is the only usb c equipped computer i have..my roomate has a gaming dell laptop, but it doesnt have one:/

Thanks for the reply, any suggestions on how to test your theory?

Hello guys, I have a very interesting problem with my working station. Inspired by the cleanliest setup LTT video I wanted to create a one-cable desktop station for occasional gaming and office work. So I got myself a Phillips 27" monitor with usb c dock, which provides 3 USB 3.0 RJ45 and 65W power to my MacBook Pro 13". I absolutely love it how I connect just one usb c cable to my MB and all my peripherals light up, my MB is charged and is getting an ethernet internet as I have a 500 mbps internet connection and that makes a huge difference as due to my neighbours WiFi interference I have to have the range of my WiFi signal lowered and my 5 GHz WiFi is giving me just 20-40 Mbps. And the internet connection is the problem. My internet providers protection software (??? not sure how to call it, I'm not really an IT guy) started to shut down my connection whenever my MB is connected via RJ45 using usb c which is also powering the MB because of "packet storms" that would occour according to them. I found a few threats on reddit reporting the same issue but noone really has a solution. I also have this problem using a usb C dongle with both rj45 and powering. I also tried two different ones, no luck. So it seems that when the MB is connected with one cable with both power and internet it causes some ghost packet requests which make my provider disconnect me. We went through 4 technicians visits, 2 new routers, rewiring the whole network, they even changed the cisco switch in the basement which is providing the whole apartment building. Through this lenghtly process as we eliminated all the usual options I came up with this and it seems to be the true problem. As I am now writing this, I thought of one more thing to try, I will connect the monitor/dongle to one Thunderbolt 3 port and a usb c to rj45 adapter to the other and see if it helps, I will report back. But that would kill my one cable solution I absolutely love. Does anybody have the same problem or even better a solution to this? Im getting desperate here. Thank you very much and have a great year 2020. Regards, Ondra
