What I see from the logs there is that your wired interface gets reset very often; this might be indicative of an issue with the network, not the system itself (or NM). If you use a different location to plug your system (or even a different building, at home, whatnot), do you still get the same low performance?
Setting Incomplete for now until we can know more. If performance doesn't improve, this will need to be looked at by the kernel engineers, since something might be going on at the driver level. ** Changed in: network-manager (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/871115 Title: network connection very slow with msi 7673 internal NIC Status in “network-manager” package in Ubuntu: Incomplete Bug description: Using stock MSI 7673 board with the following setup: Quad-core i5 16 GB DDR3 ram Radeon 5770 GFX card MSI 7673 Mobo with stock NIC Running stock natty, installed today.
