Setup:
- I have a Gigabyte GA-B150M-D3H motherboard with an Intel i5-6500 CPU and 8Gb DDR4 GSkill RAM.
- I have wired ethernet with a CAT5e cable plugged from the Ethernet port into a TP-Link Gigabit 5 port switch and then eventually onto a TP-Link ADSL2 Router.
- I am using a static IP setup (Static IP, Gateway, Subnet mask).
- I am running Windows 10 Home 64bit
- I am running Kaspersky 2017 Internet Security (I have uninstalled Kaspersky Secure Connection)
- I am running the supplied Gigabyte drivers for the Intel Ethernet Adapter on the board (Version 20.7 - listed as 12.15.22.3 in the driver properties)
Problem:
- Waking from S1 sleep causes the adapter to intialise at 10Mb/s and have no connectivity. The only solution is 1) reboot or 2) remove and re-insert the CAT5e cable. This cable has worked at Gigabit speeds for years on the previous Motherboard I had which had a Realtek based ethernet adapter on a GA-X38-DQ6.
Event Logs:
- When the problem occurs: "Intel(R) Ethernet Connection (2) I219-V Network link has been established at 10Mbps full duplex."
- When the system works fine: "Intel(R) Ethernet Connection (2) I219-V Network link has been established at 1Gbps full duplex."
Things I have tried:
I have tried the following Intel drivers:
- 20.4.1 (from the Intel site)
- 20.7 (from the Gigabyte site)
- 21.1 (from the Intel site)
I have tried disabling all of the power management properties in the Intel driver properties
