No Gigabit Z77 Extreme4 LGA 1155 Intel Z77 Win10

For starters, the "Speed & Duplex" drop down is displayed correctly. And Auto-Negotiate is proper for 1Gbb connection. One would only need  "Force' a lower speed than Gigabit.

Secondly, you've somehow managed to look everywhere except where you should in asking "Does this chipset just not support Gigabit on Windows 10??""

What color is the LED on the NIC port at the rear of your Computer?

Right click Start > choose Network Connections > double click your current wired adapter ; and what is your connected speed?

Are you maybe using a free-standing 10/100 Switch between the computer and Gigabit ports of the new router.

How you could not tell which driver at Broadcomm is newer is well beyond me. They are clearly labeled. Latest is 17.2.0.2 as of today.

wardog, while I appreciate the response, there is no reason to be rude to me.

1. I know there is no need to force negotiation speed, but 1.0Gbps should be in the list if the driver supported that speed. You CAN Force 1.0Gbps but no real reason to, but it is not in the list which means with my current driver I will not get 1Gbps. I posted the screenshot to show that, even with the cable disconnected, 1Gbps wasn't displayed as a speed option. If the chipset and associated driver were even CAPABLE of 1Gbps it would show up in the list regardless of where or what I was connected to.

2. This shows that with the latest driver I could find for my specific chipset, On Windows 10, 1Gbps isn't in the driver.

3. I was at the link you provided before I posted. If you do a Ctrl + F and search for my chipset, BCM57781, you will find 17.2.0.2 is NOT for MY chipset. The lower items are diagnostic tools that ARE for my chipset. The latest driver I could find from Broadcom or ASRock is the version posted in my schreenshot. This is why I posted, to see if someone knew of a URL elsewhere for a newer driver for BCM57781 or god forbid I made a human error and over looked it.

4. I already told you I am connected at 100Mbps, my NIC reports it as does my business class SonicWall TZ-215.

5. I am not using a switch, right from the router port to the NIC. I have tried other ports on the router that work as gigabit for other devices, but I know this isn't a cable or switch or router issue as the 1Gbps speed option doesn't show up as an option for my NIC even with the ethernet cable disconnected. I know in modern times there is no reason to FORCE a negotiation speed, but my point was that, according to the driver loaded, 1Gbps isn't an option on Win 10. It was there in Windows 8 for the same driver. It is a driver issue with Windows 10.

6. If you look at the last sentence of my original post, yes, I indeed DO ask if Windows 10 supports Gigabit with this driver.

It is likely that since this an old chipset on an "old" board there is no newer driver for this chipset that enabled gigabit for Windows 10. That is why I am here asking if someone knows of one.

F it dude.

ipconfig /release

ipconfig /renew

Or simply have rebooted the machine and let it renegotiate to gigabit with your new router. Either way is the proper and correct methods when one installs a new router. You're thinking too hard about this and as a result seem, by me anyways, blinded by your thoughts. Just re-read this thread all over again. Your/this apparent stubbornness comes right to the surface.

It was ^^^ line you wrote above, that upon my re-reading, is why I suggested the ipconfig command, or a reboot. 99.99% sure I am that your doing one of those connected you at gigabit.


You must have gotten lucky in the router lottery to have gotten one that has the same DHCP Pool of IPs otherwise you wouldn't have even been able to connect to it at all immediately after swapping that 10/100 over to the 10/100/1000 router.

Again, and only after re-reading, did I realize you most likely only needed to issue those commands or reboot and let your "NIC/Driver" realize gigabit after it renegotiating itself with the NOW gigabit port(s) of the new router.
