Have anyone had any network problems with the card? Thinking about the onboard nic from Intel. Am having troubles with download speed, it's nowhere near my isp limit, and i've tried other computers on the same network, router and cable. Installed a standalone nic from Intel, and right away i got correct speeds. Anyone got any clue? Defect onboard nic?
Have you tried testing transfer speeds from integrated NIC to some other PC on same network?
It could be driver problem or just some settings in driver.
I had that kind of problem on some other boards, usually correct drivers solved the problem.
Also keep in mind that cable cannot be tested without instrument, I had cables that were problematic and sometimes keep loosing packages so speed dropped a lot due to re-transmit of packages.
That same cable have been tested with instrument and sometimes it had 8 pin connection and sometimes didn't.
I've used iperf to test between two computers on the same network yes, and the download performance is very bad. I've also tested windows with different drivers, and linux, but still the same problem. On the B250, only thing giving me the correct download speed at the moment is the standalone nic i plugged in. The onboard gives bad download speed in every scenario i've tried it in so far, only thing i can think of at this moment is hardware issue :/
