It's highly unlikely, but switch ports CAN go bad. If it doesn't change ports, then the problem is the switch port.

If the 100mbit connection changes to the new switch port, the problem is in the walls. Leave the laptop plugged into the same wall port, and change the connection at the switch. If it changes, you now know the problem is somewhere between the wall jack and the switch. IF the test works and you get 1gig, THEN move the good cable and the laptop back to its original port and test again. If it fails, you know the problem is isolated to the laptop, either the network card is problematic, or the drivers are. If you have a laptop running 1gig on its own port, use THAT port, and THAT cable to test your unknown laptop with. Test the hardware with known working equipment, and change AS LITTLE AS POSSIBLE each test. Some of the ASUS ROG laptops using it would get stuck in 100mbit if Green Ethernet was enabled. Acer laptops that used them wouldn't go over 100mbit until they got a BIOS update into the v2.0 bios releasesĭell XPS Laptops would get stuck at 100mbit if a Microsoft driver was in use that had a specific version number that was actually for the 8172/8176, which is only 10/100. The Atheros 8171/8175 NIC has been troublesome since its release over 6 years ago. Microsoft's last driver release for this card was 2.1.0.27, in Oct'17 There is a lot of interference on the wire. The computer adapter is not set to auto negotiate. The cable is damaged or wired incorrectly.

As you can see there is nothing about 1Gbps in the 'Speed & Duplex' property while NIC is Gigabit Ethernet !!ĭoes it mean that NIC doesn't support Gigabit speed?
