Slow transfer rates when connected to switch?

[Gundam]

The way I have my network setup at home is as follows:

Cable Modem>Gigabit Router>Powerline Adapter A> Powerline Adapter B>Gigabit switch>Laptops

I have an Unraid server hooked directly to the router and it stores all of my files. What I'm trying to accomplish is allow my two laptops upstairs access to the server. When I hook up my laptop directly to the router, I get transfer rates of about 60mb/s. However, when I go through the switch I only get around 6mb/s if I'm lucky. At first I thought it was the powerline adapter, but when I removed the switch out of the equation and hooked a laptop straight to the powerline adapter, I get transfer rates of 60mb/s. I've tried two switches (although both are from the same mfg) but get the same results. I've even tried bypassing the powerline adapters competely and hooking the switch straight into the router with the same results.

That does seem to indicate a problem with the switch.

(Or your cables.)

Is there a special way I have to hook up the switch? Like specific port numbers are recommended for certain tasks? Or can you just plug in wherever you want?

Can you confirm that you have the correct speed/duplex settings on the switch and the NICs in your laptops? You stated that the switch is gigabit, so, assuming that the laptops have gigabit NICs, they should be set to auto/auto.

Edit: what make/model switch?

TRENDNET TEG-S80G

and

TRENDNET TEG-S50g

Don't really see much to set on the switch. No buttons or anything to set.

Yep, sounds like a duplex mismatch. Make sure everything is set to autonegotiate.

As you can probably tell, I'm not the brightest bulb when it comes to networking. How can I set everything to autonegotiate. Im in windows 7

Most powerline adaptors only run in half duplex also. If the port on them is only 10/100 the gig switches may need to be forced on those ports.

Ok I found the autonegotiation option in windows device manager for my ethernet port, but it's already set to that on default.

Make sure nothing else is plugged into the switch when you test. Rule out loops, etc.
