Hello,
I have a DELL Latitude D830 with the integrated Broadcom NetXtreme 57XX NIC.
I just upgraded the old switch to a new gigabit one (DLINK DGS-1008D).
The manual in PDF format states that it supports jumbo frames.
So far so good.
The desktop computer has an ASUS P5KR mobo with onboard Marvell gigabit NIC adapter. I did set the maximum frame size to 9800 on the desktop.
When I connect the laptop to the network, it says it connected to 1Gbit, (and the switch seems to confirm that by the color of the corresponding led) but the transfer rate (while transferring HD movies from the desktop) is only around 12000 kbytes/s (verified with Total Commander)
The laptop is running Vista 32 bit, with servicepack 1,
specifications are:
CPU: T7300 Core 2 Duo 2 GHz, 4 MB cache, FSB800
2 GB DDR 667 dual channel
video on-board
S-ATA 120 GB 5400rpm HDD so the transfer speed isn't an issue.
The main problem I see is that in the card's properties there is no frame setting. So, I cannot change the frame from the default value.
I should have got much better transfer rates. I dunno what the problem could be.
My best guess is that this could solve the problem (seting the maximum frame size to 9600 for example) - but as I said, the driver does not show the property for frame size.

Any help/ideas will be greatly appreciated.

Thanks in advance, Dan
