    Hello,

    i started to have problem with my network card .... i am back on windows 7, and the problem is that when i "download" a file from my server with jumbo frame enabled i get sub 50kilbits performance.... when i "upload" to my server i get 70MegaBytes performance.

    i've checked my equipment all is jumbo frame enabled (managed layer 3 switch ), other computer in the house don't have this problem. and server is quite beefy, i have a mix of SSD for os/vm, and 6x2tb raid 6, on a 3ware 9650SE , wich bench at around 350 to 400MegaBytes / sec. SSD are in raid 0 on a ibm m1015 raid card... getting 500MegaBytes /sec bench....


    i tried my laptop at work and same problem.

    jumbo frame on , i can't receive file really fast,,,,
    jumbo frame off , i get 50MegaBytes upload/download .......



    anybody as experience with this card in particular? and why would jumbo frame do that? is my card dieing ? ( i tried DELL drivers 2.0.14.15 and atheros 2.1.0.17)

    thank you
