I am wondering if most people are not complaining about it, because it is probably not noticeable for web browsing (web browsing naturally has latencies involved). It is a killer for streaming stuff in "real time" between two machines, though. On my current machine with a 8111C NIC, I have disabled that NIC and bought an Intel e1000 PCIe NIC. That has solved the problem on that computer, but I want to build another computer, and it seems like all the new motherboards have the Realtek 8111C on them. Should I try the "official" driver from Realtek? How hard is it to integrate? Thanks, John -- A: Because it messes up the order in which people normally read text.
