For many years, I have used a TL-SG1008D switch connected to my ISP provided router, then used two ports to activate two rooms in my house for Ethernet connectivity. I had 100MB and there were never any problems. After increasing the number of devices to my network for security, I decided to increase my bandwidth to 300MB. After the install, I had WiFi connectivity to the router but no Ethernet connectivity. I worked my way from the router to the Switch and confirmed that none of the Switch ports will connect to the Internet. I have confirmed Ethernet connectivity at the Router. I have confirmed cable continuity between the Switch closet and the rooms. I have reset Winsock, DNS Catalogue, IPconfig, etc. I have rebooted every device in sequence (router, switch, computer) after a minimum of 3 minutes of power down. I have tried other computers and I have wasted 8 hours on a problem that should be resolved with a 'Plug and Play' unmanaged switch device.

OS: Windows 10
Ethernet controller: Intel (which has been uninstalled and reinstalled)


What am I missing?
