I've an interesting problem. I connect my XPS 17 9720 to the internet via an Orbi. after a while, including when nothing is happening, the orbi moves to 'connected, no internet connection'. to fix this, I have to run cmd and run the release, renew & dns flush via ipconfig. i then tun off and on, and its fine again. for a bit. I left the computer a lone for a while just idling, and a little while later, it had remove the connectivity. I'm fully up to date on drivers, and it only happens on this device (including if I try the same thing through a 5G mobile hotspot. 

Does anyone have any thoughts?
