Layout of Network: Home setup and layout. Frontier Fios (50Mbps down and 20Mbps up). Box is outside in the backyard wired with a 50ft cat 7 cable to an Asus switch inside the home. A 25ft cat 7 then runs to a TP-Link ARCHER C9 router providing wireless for the back of the home. Another 100ft cat runs to the front of the home to another TP-Link ARCHER C9 router providing wireless Internet for the front of the home. Home size totals 3000sqft. Problem: Computer with issue is directly connected to the switch via 3ft Ethernet cable and is the home media PC for the family room. PC was built a year ago by me. Attempts Tried: Motherboard (GA-F2A68HM-H (rev. 1.1)): http://www.gigabyte.com/products/product-page.aspx?pid=5368#ov Things tried (in order): Disabled the port, re-enabled the port, troubleshooted the port, uninstalled the port, reinstalled the port. Plugged Ethernet into different port on the switch. Tried another Ethernet cable. Purchased Ethernet-port network adapter TP-Link Model TG-3468 (V2): http://www.tp-link.com/ph/download/TG-3468.html Installed drivers for it from the link above. Same-exact-problem. Reinstalled Windows 7 Home x64bit. Installed driver for motherboard Ethernet port and driver for the network card. Same problem still remains for both ports. It's 2 days later. I want to donate this PC to Earth's orbit.....
This topic is old but I thought I'd come back and state the solution I found: Switch was partially failed. I moved the router that was closer to take its place. So far so good (a little over a month later since posting here). I've had a previous older model Asus switch fail on me before. Noticeable brain fart on my part... lol!
