    I've installed Server 2012 on my home desktop. However since doing this the internet access is Extremely slow, around 3-4 times slower than before.

    The slowness has been observed in general use of Chrome on the OS. It seems that maybe setting up and closing connections is slower ?

    It appears there is something wrong with the TCP/IP stack ?

    Windows installed generic drivers for the Marvell 88E8056 Gigabit NIC.

    It was slow with these drivers so I tried older 64 bit drivers from Marvell and saw no difference.

    I've disabled or uninstalled everything from the interface in question exception Client for MS networks and IPV4 support.

    The IPV4 settings are set to the defaults of DHCP etc.

    I have tried disabling 'Large segment offload' again seemingly without effect.

    I've tried disabling the firewall and real time AV but saw no difference.

    I've tried resetting the TCP/IP stack, without effect.

    Any ideas chaps ?

    Is this possibly smart screen (I've turned it off, but maybe a bug) ?

    Stupid question, but have you rebooted the router? Is it the same on another device you have? Done a broadband speed test?

    Router works fast for other Wired and Wireless devices.
    Router has been rebooted.
    Speed tests have been made, speed tests report ok speeds.

    It appears that every HTTP connection has a lot of latency or that something is causing a delay opening/closing connections.

    Similar delays happen in Firefox and Chrome, probably in IE 10 also but IE 10 still locked down so not used much.

    The Windows Server 2012 is a clean install, the system was working fine in same configuration on Windows Server 2008 R2.

    Its possible the NIC drivers are maybe just rubbish for 2012 ? I'm not aware of any changes to the driver model in Server 2012 ?

    Don't have an issue on mine (noticably anyway) but I don't have a Marvell NIC.

    How does the ping look like? Can you try using Fiddler2 to see if the delay is caused on request or response?

    Ping times are normal around 30ms.

    Firebug shows 'normal' page load of certforums at ~3 seconds, the Windows Server 2012 machine with issues loads the same page in 30+ seconds.

    Basically TCP/Connections seem to take a long time to set up and tear down.

    Changing the MTU seems to have helped a bit, but it still seems 3x slower than it should be.

    Any chipset drivers available for the motherboard? Can sometimes help.

    Non of the Mobo drivers from Asus have Windows Server 2012 compliant installers, I could frig the installers to get these old drivers installed, but doubt it will help.

    There are no issues reported in Device Manager.

    Have you got a secondary NIC you can throw in to test?

    I was under the impression that 2012 was backwards compatible with 2008 drivers. You can probably just extract the drivers from the installers and use those? (Open the installer in 7-Zip should do the trick).

    I have tried three versions of the Marvell drivers, some WHQL, some not, none seemed to make a difference.

    The MOBO has two NIC's but both have same issue.

    Will have a look for an old NIC card around the house, if I have one it will be ancient though...

    Worth setting the NIC speed to 10Mbps? Probably on auto-negotiate just now.

    It might be worth doing a tcpdump to see what packets are actually being sent/received?

    Disengage Linux brain, engage Windows brain.

    It might be worth using Network Monitor / Wireshark to see what packets are actually being sent/received?

    Wireshark won't install, Winpcap is not compatible with Windows Server 2012.

    I installed Network Monitor before, but their drivers are supposed to be possible of causing extreme slow down so removed it.

    sorry for my poor english.

    The way to fix this problem:

    netsh interface tcp set global ecncapability = disabled

    The reason for this problem is:

    Route is not compatible
