Ethernet gets slower with time - Yosemite

[Coonaps]

Hi there!

I am on Gigabyte Z87x-D3H and using the newest Multibeast. Everything is working including the ethernet connection. But the connections gets slower with time an I mean painfully slow. If I for example start writing some stuff to my NAS the file transfer starts quick but slows down with time. At around 1,8gb it gets so painfully slow that i have to abort the process.

Windows transfer speeds are not dropping.
Any ideas what the solution to the problem might be? Any help would be very much appreciated.

Did you find a solution ? I got a UD5H, everything is working great but network with other macs get slower over time (24h). Need to reboot everyday to avoid this problem... it behave like network data get saturated.

Try a different ethernet kext.

Mieze's IntelMausiEthernet.kext works great on many systems.

I'm having the same problem with ethernet getting slow after 24 hours. on a Z87X-UD5H Running Mojave 10.14.2. I'm don't see the AppleIntelE1000e.kext under /System/Library/Extentions. It's the IntelMausiEthernet with the GA-Z87X-UD5H? Did that fix the network slowing down problem?
