Help with GIGA Switch

[Nhilar]

Okay guys I am having some strange problems.

Previous set-up:

ASUS-520gu 10/100 router flashed with DD-WRT.

All works great, most devices attached are 1 gig, but not all, so it all defaults to 100, I can get a sustained 10 MB/sec when copying large files (Megabtyes, not Bits).

Opps running out of ports, so I buy a DGS-2208 (get it for 19.99), giga switch and put all the 1 gig equipt computers on that so I at least can get giga connections between them.

Get ready for it????.POW????
The transfer rates drop to ~500 kb/sec!

Details:
A computers running Vista Ultimate,

All computer report being connected at 1 gb, as does the switch.

I?ve goggled the slow transfer problem and tried all the remedies suggested; turning off various VISTA features, switching the link rates to Auto Negotiate, turning IPV6 off, turning tuning off and so forth, no go.

Tried removing the router so that the giga switch and giga devices are isolated, same transfer problems?.

I am lost here guys, please provide me your wisdom!

What kind of cables are used and are they homemade?

 

[Nhilar]

Standard store bought CAT5, 3-6 ft lengths.

Get some Cat-5e or Cat-6 cables.

I thought on short runs it makes no diff, well I will give it a try thnaks!

Sure, they might work but not all cables are created equally! By getting 5e or 6 you're getting cables who's minimum spec still allows for gigabit. I'm sure spidey07 will offer more details if you ask 😉

and dont get em from a store, you get raped on the price. check monoprice and get a couple for cheap

yeah, that should solve your problem. And yes, don't buy anything that says 'belkin' on it as you'll be paying 10x too much! LOL

Update:

All the cabling is replaced (Cat-6). Marginal performance boost, from 300-500 kb/sec to 700-800 kb/sec.

Enabled large packets on each computer, disabled flow control on the computers, disabled Vista QOS?Now doing ~10 MB/sec, still not very good for a giga set-up.

Replaced the DLINK ?green? giga switch with a NEtgear 8 giga ?smart? managed switch.

BAM: 60 MB/sec burst, 30 MB/sec sustained?

Only one problem, on occasion it stalls, by this I am the activity lights on the switch stop blinking, remain on and the transfer stops, then 10-30 seconds later it resumes and the lights continue to blink, so a typical scenario would go like this:

Starts at 40-60 MB/sec

Settles to 30 MB/sec

And random times it stalls, lights on the switch remain on and the transfer pauses, 10-30 seconds later, lights begin blinking,

Transfer rates drop to 20 MB/sec

Climb back to the 30 ? 40 MB/sec

Rise, repeat.

How many devices are attached? Have you tested it with just 2 PC's on the switch?
