If your switch is giving you trouble, a used Dell Powerconnect switch is a good buy. I get less lag and far fewer dropped connections since I upgraded to one.
It only takes a few seconds to verify all of them are good. This rarely works, but most network chipsets give you three choices of drivers: one from Microsoft, one from the company who sold you the card, and one from the company who made the chip on the card. You can try different drivers and see if one of those will sync up at gigabit. The last time I saw this work was in or , and clearly it was due to a bug in a network driver that one of the alternative drivers fixed. Realtek-based cards are really cheap these days.
If you have a gigabit card only connecting at mbps, the last resort is to replace the card with another one. Also beware of PCI-X cards. Broadcom and Intel cards are less demanding on the CPU, and tend to be made of higher-quality components since they usually go into corporate environments. Even if you get gigabit Internet , only expect to get percent of the speed.
The only setting that is of concern for a Gigabit connection is that the adapter is set to Auto Negotiation. This is the default setting. We have had reports of some ISP technicians telling their customers that a Gigabit option will appear in this setting if the network adapter is working correctly.
This is incorrect. There is no option for 1. Auto Negotiation will give you a 1. If this is set correctly and your link speed still reads as Mbps, then the issue is almost always an issue with an Ethernet cable, though it could be a few things.
Before troubleshooting any further, check the connection of the Ethernet cable into every piece of networking equipment, as well as your computer. Make sure each cable is labeled Cat 6 or Cat 7. Unplug each Ethernet cable and plug it back in. Make sure that your cable is pressed firmly into the Ethernet jack.
You should hear and feel a very audible click sound when the cable is in place. If you do not feel and hear this, then this cable should be considered broken, and you need to replace it.
Even if you believe that your Ethernet cabling is perfectly fine, and even if this cabling worked fine before, swapping it out for another, proven cable, or a brand new Cat 6 cable, will almost certainly solve the issue with the minimum of troubleshooting and headache.
This is a very, very common occurrence when troubleshooting Gigabit Ethernet, and it nearly always comes down to one cable being the culprit. Note that this includes all cabling between the machine and the router, including any cabling in before and after any switches, or on the other side of any wall jacks, and behind the wall. A faulty cable can lead to connectivity, continuity, and performance issues. The network jacks on both ends of the cable can also be the cause of the issue, as well as any damage between the connections.
Changes to any of these settings can lead to a reduction in transfer speeds. After downloading and registering the application, it will automatically keep your PC up to date and improve your performance.

He was negotiating the right link speed, but wasn't getting good performance. I found 2 interesting things one is gigabit master slave mode, which is set to auto detect. And Speed and duplex which is set to auto negoitaite. I do not know what that first one is but ill try chaning the second one and see if anything happens.
I don't think it'll matter, but the manual setting for "gigabit master slave mode" would be slave. If it makes no difference, set it back to auto-detect.
Instead of auto setting, manually set speed at 1Gb, duplex. Then see. In the device manager can you see manufacturer of the NIC card. Even tho Windows says latest driver, you can check the manufacturer site to see if there is latest driver. I manually set duplex mode to the 1gb option. The computer did not even detect the ethernet cable pluged in. Tried power cyceling both pc and router still nothing, so switched it back to auto.
So I went on intels site, there is a new driver. I downloaded it, and unziped it. Then instal wizard ran. Went through the whole proccess. It completed. Then checked back on device manager, and ethernet port still has same driver from last time. Overall: The common denominator in the testing is the PC, everything else seems to be working at 1 gigabit. Putting a gigabit switch between the router and the PC might work around the problem.
I was able to borrow a gigabit switch. I placed the computer into the switch and the router. The computer is still showing connection while the router has the white light blinking instead of red where the switch is placed in. Perhaps try a second test connecting it directly to the cable modem. My cat5e cable is the only 15 ft cable I have so it is difficult to test out a different cable with the desktop. But I will try to figure something out. It was just strange that same cable gave me 1gb on my laptop.
What's strange is that the PC NIC connects at mbits to both a gigabit switch and the R, but somehow manages 1 gbit with the cable modem. I just hooked up the cable in question from router to gigabit switch, and the connection on the router is blinking red.
