Not experiencing Gigabit networking speed

[Lespaul00]

Hello,

I apologize because you probably see this questions come up a lot. But I can't find any support online for my particular situation.

I have my house wired for Gigabit networking, but the fastest speeds I've seen are 8MB/s. I've only seen that speed once (today), and every other time around 3MB/s. I move large files around so even if I can get the speeds to 30MB/s, would be great.

This is my set up:
Sony Vaio PC --> TRENDnet 8-port Gigabit Switch --> WNDRMAC netgear Gigabit Router --> WD TV Live Hub

Sony Vaio:
- Does have a Gigabit NIC

TRENDnet 8-port Gigabit Switch
- TRENDnet 8-Port Unmanaged Gigabit GREENnet Standard Switch (8 x 10/100/1000Mbps Auto-Negotiation, Auto-MDIX Gigabit Ethernet Ports) TEG-S80G

WNDRMAC netgear Gigabit Router
- IEEE 802.11 a/b/g/n 2.4 GHz and 5.0 GHz
- Five (5) 10/100/1000 (1 WAN and 4 LAN) Gigabit Ethernet ports

WD TV Live Hub
- Gigabit Ethernet, USB 2.0, HDMI, Composite A/V, Component video, Optical audio

All ethernet cables used in my house are Cat5e.

The light on my TRENDnet switch is green, not amber, for my Vaio connection.
The light on my TRENDnet switch is green, not amber, for my Router connection.

I cannot seem to find out how to see my connection speed between my router and my WD TV Live Hub.

I also experience the same issue with my NAS... which is a Synology DS211j. That too is connected directly to my router.


Thanks!!!

Just, because you have everything wired for a Gigabit doesn't mean you'll get it all the time and everywhere. Are you sure your computers motherboard supports a Gigabit? Many computers have only 100Megabit support. Secondly, your router may have issues dealing with a lot of data traffic. You can get a more powerful router.

I move large files around so even if I can get the speeds to 30MB/s, would be great.

Do you mean large folders with files? Large amounts of files? Or actual large files themselves.

When you transfer large files over, it is usually faster than a bunch of smaller files due to TCP/IP.

Thanks for the reply.

Yes my computer supports gigabit ethernet. Yes I am moving one large file, not a folder with many files. And I just purchased that new high performance router that should have no problems with gigabit speeds.

Any other thoughts? Could it be because the signal goes through my router again? Should I hook everything up to the switch instead and just have 1 ethernet cable from my router to the switch?

yes yes yes... use the switch to connect the computers and the router to assign ip's. if its logistically proper. switches are faster devices as they work on layer 2 and thus dont need to DE-encapsulate the ip address headers to send packets between computers. routers are layer 3 devices and thus require more time with the packets. now this will add up to perhaps 1ms delay during light load or 2-5ms delay on heavy loads. the setup you have now should give you faster speeds but its worth noting that your computer will list MBps while your network is Mbps. thus in a perfect world you would get a max of 125MBps transfer speed and in reality perhaps 100-115MB/s. go into your nics settings and set there link speed from auto to gigabit full duplex and ensure your routers port is also set that way.

Hey thanks a bunch! I will try it out and post back.

Much appreciated!

How did you get on mate? I've just recently made the switch (hur hur) to gigabit but until next month I am using a 2m cat6 patch cable direct connection between the machines. Using onboard realtek ports I am getting about 40-50megabytes / second.

Maybe you should try doing this and seeing if it's the NICs or maybe even the harddisks in your computers that are limiting you.

Wished I had a connection that was 30/5. I have 6/.5 (seriously). Death to T-Mobile.

16/4 is average speed around here. it comes with cable tv packages and is fairly standard. i think the lowest you can get is a 12/3. higher end cable packages go to 25/5 then 50/10 and finialy 100/18. you can if you want pay more and get static ip addresses, they charge 5.00 per block of 4 and with a static ip you can then get a 150/25 line.

with the higher end lines you dont get a cisco cable modem but rather a cisco 1800 series rack mount modem.
