gigalan running at 30% speed,,,, WHY?

[V_LESTAT]

ok this isnt for me its for a buddy who just got his gigalan set up.

he has a server which he runs and also a desktop , they are both connected to the netgear GS605 Gigalan Switch, which in turn is connected to a Linksys 5 port router.

Server NIC - Netgear GA311
Desktop NIC - Onboard Realtek 10/100/1000
Router - Linksys BEFW1154
Switch - Netgear GS605
Both PC's Running XP Pro

Whenever he enables Jumbo frames in the NIC properties his LAN goes "MUTE" - Mute meaning he can see his server but can not remote into it.
but he does not loose internet.

the netgear gigalan application says he is running at 33% bandwidth when testing LAN speeds with large files, rinning something like 280mbps

The more he messes with it the worse he gets and right now he is running less than 100mbit.

the netgear switch has NO web interface for administering the switch. which is a total pile of poo and netgear took the cheap way out.

Help me help him out.
none of the NIC properties that he changes helps, infact it either kills his LAN or makes it worse. it seems like he can NOT run Jumbo frames or it dies. which is wrong since gigalans use jumbo frames.

what settings in his NIC properties should he use and what tweaks can he use in order to maximise his gigalan while still maintaining his speeds for internet.
i dont want and he dont want these tweaks to be so high that it causes his internet to go to hell.

can you gents help.

wow no one running gigabyte network LAN wants to take a stab at this ?

bump

h e l p steele or coffee ??

beats the hell out of me??!?!?
Perhaps make sure firmware is updated on the router and gigalan???? Hmm maybe hooked up backwards? Or the squirrel in the wheel isn't running fast enough to give ya enough power? LOL

[V_LESTAT]

yeah i know what you mean,

we thought it was looping thru to the router which is only 10/100 but even removing it the max he gets is 286mbps.

its a brand new netgear,,, as in brand new to the market,,, netgear just released it. there isnt even firmware posted for it

you could try a p2p connection with a small cable (about 5 meters, shielded).
Also try to transfer files from ramdisk to ramdisk.
If speeds goes up, defrag your HDs, (theoretically 100%gigabit=125MBYTE/sec !!).
If you use to transfer large files using cluster sizes >= 16K may help also.

Else, check your drivers/nic adapter.
