I have an old win xp pc with a DAVICOM network adapter connected to a Pace 4111N gateway using Ethernet cable. That setup works fine.
I also have a win 10 Dell desktop pc with a Broadcom NetXtreme 57xx Gigabit Controller. When I move that Ethernet cable to my Dell desktop pc it takes minutes to open a web page and most of the time I get “server not found”. Win 10 says that I have an internet connection, the diagnostics say no problem found, the device manager says the device is working properly and the router shows a connection to the pc. Any ideas on this? Thanks
