Personally I have had no issues with network dropping out on my replacement device but that is a shame that it likely is a hardware issue for the wired port. I’ve tried multiple drivers/driver settings/bios changes with no luck. What kind of Wi-Fi speeds do you see? For me best case it tops out at around 65Mbps but I am unsure as to what I should expect given the specific hardware, just assumed it should be much faster. Last week I emailed Chuwi aftersale support for clarification on the bogus marketing specs for the HeroBox and received no reply.
