[Windows] Getting slow transfer speeds on Giga lan

I have a Asus 802.11ac AC1750 (RT-AC66U) and I have two TRENDnet TEG-S80G GREENnet 10/100/1000 8 Port Gigabit Switches. I am using Windows 8.1 on my PC and transfering files to a media box (Pivos Aios).

When I transfer files over LAN I keep getting max speeds of 4mb/s is that normal?

try iperf between 2 computers. i have seen those trendnets hit 980mbit transfer rates, so its not them

I did an iperf test and I get max 82Mbits/s, could it be my router limiting the speeds?

the media box is on the local network yes?

prolly the media box

This was between 2 lan connected PC's. The media box is also lan connected.

well logic says if 2 pc's can do 82mbit, and the media box can do 4. its the media box

looking at your iperf, that was per stream , thus significantly faster

edit: The spec page finally loaded and it looks like this thing doesn't have local storage, so you can pretty much disregard what I wrote here before.

You may want to try swapping switch ports and network cables to rule those out. If the Pivos is slow on a known good switch port and network cable then you may want to confirm that it is connecting to the switch at 1000 Mbps full duplex.

4mb is not even touching 100mbit, its not a switch issue

A speed or duplex mismatch can make things crawl. If the switch reports 1000 and the media box shows 100 or 10, then actual transfer speed will be well below 10.

Also possible that the switch is acting flaky on some ports but not others. It could be a lot of things at this point. Proper troubleshooting will eliminate the possibilities.

I bypassed the switches and connected both pc's straight to the router and used cat5e cables and still same thing. 82.4 Mbits/S

thus not the switches

And when you connect the PC and the media box both directly to the router, what do you get for speed?

Looks like from what is posted on newegg reviews about the Pivios AIOS.
Some that say it is slow and one that states it takes forever to transfer files to it.
Also looking over the firmware notes second release bug of packet dropping.
Which pretty much explains your problem with said unit.
Though many firmware updates after the second one are posted.
Just seems like a problem that was maybe fixed or thought to have been.
When it has really not been fixed.
Newegg review is titled "It plays files"

»www.pivosforums.com/view ··· ?f=3&t=6

Firmware Release #: 2.8.0.5
Revision Date: 9/15/11
Download Link: HERE
Release Notes:
- Fixed audio drop during some video RSS playback
- Replaced home screen browser button with REALPILOT
- Added additional HTML 5 portal feeds
- Temporary removed Album Cover Mode (ACM) and Poster Mode (PM) for bug fix
- Fixed drop network connection caused by audio drop issue

I would make sure the latest firmware is up to date on all devices. Sounds like the Pivios is the first one I would check.

did you try jumbo frames? I had the same problem until I switched.. (no pun intended)

you had to turn on jumbo frames to get over 4MB a sec? i get 10MB over wireless alone(not AC) and don't have it enabled

Jumbo frames reduce interrupt load on the CPU, when they're used. If the Pivios is pinned it will improve throughput by lowering processing overhead (assuming the devices use larger frames when enabled, which they normally should when moving large files).

but also causing a penalty to every other device that does not support it

How so? According to this article, all devices on the local network should be exchanging MSS information to prevent frame size mismatch (see the first two paragraphs on linked page).

»www.smallnetbuilder.com/ ··· ?start=2

edit: The last page of the above article does point out that MSS discovery doesn't work for UDP, so there's one potential snag. If the OP has other devices on the same subnet that don't do jumbos, and might be receiving UDP from either the Pivios or the PC, then jumbo frames could be problematic on those devices. A workaround, which is outlined in the linked article, is to create a couple of subnets or vlans and place jumbo devices in one and non-jumbo devices in the other. The router would of course have to support jumbo frames as well, and fragment anything coming from the jumbo subnet.

yes alot of stuff use udp, actually a ton.

that said your solution is messy and unnecessarily complicated. OP proved its not the network, if the box can't do 4mb without problem, jumbo is not really going to help him

If the Pivios can't top 4mb/s (sic), then there's a real chance that jumbo frames will help. If jumbo frames does prove useful, then the user has some choices to make. Whether a segregated subnet for jumbo frames is worth the cost is for him to judge.

I agree with clarknova. Its really up in the air though on if it will work or not. The key is to try. We are not talking about a very lengthy time frame to do the work. It could be accomplished in 15 minutes or less. If it doesn't work, set it back and try something else.
