I have been plagued by the slow upload issue on both wireless and wired LAN it became especially apparent when I switched to ADSL2+
My download speeds had large fluctuations and my download speeds were only 200kps, 1/5 of what they are supposed to be.
I had tried numerous drivers for Windows 7, I NEVER would have thought to try an old Vista driver to solve the problem, but it did the trick.
Thanks again, solved a huge long standing headache for me.
