LAN Transfer Speed Slow?

[orbofshingeki]

G'Day All.

 

I have a WD My Cloud that's been on my network for a couple years now and seems to be slow when transferring files between local pcs. at first i thought it was just the cloud then i tried sharing my 2tb from my office computer and it's being limited to the same speed as the cloud. Around 11 Megabytes per second....

 

What I'm Using

Router is Netgear's Nighthawk 7500

Switch is a TP/Link 10/100/1000

Laptop is Lenovo Y50 which is also my HTPC.

All Cables are Cat 5e.

 

Please Help.

 

Thanks

What are the network link speeds? this feels like there is a like that is 100mbit.

If it's limiting to around 11MB/s, I'd expect the link to the NAS to be dropped to 100Mbps at some point. I'd first try changing cables (check the lights on the switch to see if any link isn't running at the speed it should be).

Shows 1 Gbps on the link.

Is ther only one link? There is probably multiple links. check them all.

 

Also try just plugging the mycloud into the pc directly.

on the nighthawk, the led indicator is white showing it's running at full speed, if it was limited it would be orange. i had it happen with an old switch that wasn't rated for a 1000.

Can you actually confirm the link speed on the drive? It's all well and good if the switch and router are connected at gigabit speeds, but if the drive itself is only connected to the switch at 100mbit you're still going to be limited to that regardless.

 

The chances of the drive coincidentally only getting 100mbit is infinitesimally smaller than the network link being limited to 100mbit somewhere.

If I may suggest a couple of things... just to "stress" test.

1) Don't use auto-negotiation in any of your ports (switches, router, network cards, etc..) Set up the speed to 1Gbps full duplex manually.

2) Enable Jumbo frames to test performance for large file transfers, this should have some impact on the speed and improve it if indeed your network is working at 1Gbps full duplex.

3) Enable flow control on the ports of your network card, switch and or router (whenever that is supported)
