I just purchase a parallels 16 and use windows 10 from Boot camp partition. Once the system launched I have internet connection, and I can use it to do all the things. However, after a short period of time, maybe 1 to 2 minute, the internet loss, I tried all the method I found on this forum, (such as set the internet bridge to default, scan system, ping ip in windows cmd...etc.) but non of them work. It's super weird. I used to just install the windows 10 vm from iso, and internet no problem, but some of my work need to go connect some specific hardware go through thunderbolt 3 pcies which I tried I can not directly use virtual machine to access. So I make a double boot, but I really like to use win10 vm when I don't need to connect those hardwares. Can anyone solve this issue? I use macbook pro13 2020 intel i5 16gram 512ssd, the system is bigsur. Thanks!
