Slow network speed

[Sygron]

Hello all,

I have a problem with my home network and I can`t figure out where the problem is.
Hope you can help.

I have a NAS with big files on it because of this I want to have a fast intern network.
So I bought a gigabit switch (Linksys SE2500), Put this between my computer (motherboard ASUS X79 Deluxe, using the intel port) and my NAS (Iomega ix2-200) all the devices support gigabit speed.
After this it is connected to a HUAWEI HG655d Router/Modem 10-100MBit/sec

If I am correct in this setup it would not use the HUAWEI, as I can connect directly to the NAS trough the switch.

But now I try to get a file from the NAS to the computer and it downloads at 10 Mbit/sec.

How is this possible what am I doing wrong to get it this slow....
I would expect a speed that is 100x faster, or at least 10x faster.

Added a few screenshots of what I have tested and seen.

Any help is greatly appreciated.

I know this may sound like something simple; but; have you tried something as easy as unplugging the power plug(s) to the associated devices and rebooting them to get them to "reset". If not I would go ahead and try that simple idea first. Sometimes just resetting them will get them to reconnect at the proper speed. If not; I would check the adapter properties for the proper settings. I cant tell you specifically what those settings would be since I havent had experience with a lot of networks per say but what i mentioned so far is worth a shot.

@matts6887: Thanks for the suggestion, however it didn`t work.

Did some testing in the mean while though.
1) Tested with my computer and a different computer, just one cable in between and transfered a large file.
Speed went up till 120 MBit/sec. Looked up on wiki 1 Gigabyte is 0.125 gigabit.
So calculating it back it matches.

2) added the newly purched gigbit switch so Computer -> Switch -> Computer.
Still same numbers so that goes great. (Switch works)

3) Tested my computer with the switch and the NAS, I go back to 10 MBit/sec.
BUT, I tested with the other Computer from test 1 and this gives again ~120 MBit/sec.

So 2 computers that work great together but once seperated they give different speeds...
I know this doesn`t make the problem easier but I can`t get my head around this...

I notice you have an ASUS motherboard, do you by any chance have AI Suite installed?

 

[Sygron]

No I don`t have AI suite installed.
I do use MSI afterburner for logging purposes of the temperature.
Why? can AI suite help solve this problem in any way?

Quite the opposite, the iNetwork Control in AI Suite can seriously cripple network speeds as I found out the hard way. At least that's one possible cause ruled out.
