Readynas NV+ v2-Slow Network Transfer Speed

What version of RAIDiator is on your NAS?

What brand and model disks are installed?

Are you sure those 2 MB/s speeds aren't only when your laptop is connected over wireless? 2 MB/s sounds like 802.11g speeds. If connected over ethernet you should be getting much faster speeds than that.

Raidiator 4.2.24

they are all 3tb barracuda SATA.

I have tried it wireless and wired using cat 6 but it makes no difference it is still never exceeding 2MB and that is the top speed. It is usually a lot lower?

If you are running 4.2.24, then you do not have an NV+ v2. You must have some form of pro or ultra.

If you log into Frontview, what model number is displayed on the home page?

Also, can you look at your router status, and see if both the NAS and the PC are running gigabit ethernet?

Sorry my mistake, i just logged into frontview and my radiator version is 5.3.8.

My router does support gigabit, my wireless card is an intel centrino wireless n2230 so capable of 300mbps and my ethernet is realtek PCIe FE family controller.

I understand you have a gigabit router - what I was asking you to do was to look at the LAN connection status in the router, and confirm that both the NAS and the PC were actually negotiating gigabit with wired ethernet.

On WiFi: do not confuse link speed with real throughput. For instance, the 802.11g link speed can reach 54 mbits, but throughput is limited to about 18 mbits. 802.11n also has much lower throughput than the link speed. It is generally best to start with wired performance, and get any issues there resolved before starting on WiFi.

Do you have any ethernet switches or hubs in your home network? Or just the router?

Oh sorry my mistake, how would i check this?

Ok i will focus on a wired connection first.

Just the router. It is router with my NAS and laptop connected via ethernet.

If you log into your router's admin web page, you should be able to see the status of each ethernet connection.

You have a virgin media superhub? They seem to do a good job of hiding their router manuals. But there is a guide here you can use http://help.virginmedia.com/system/self ... TYPE=Cable

Once you've logged in, you should be able to find the LAN status in the device status or advanced device status somewhere.

Perhaps a faster way is to look at the ethernet status lights on the back of the hub. They are described here: http://help.virginmedia.com/system/self ... TYPE=Cable

Green -> gigabit
Amber -> 100 mbit.

My ethernet is orange so not gigabit.

On some forums i have found that by going into 'control panel', then 'network and sharing', going into the properties of my network card and configure i have disabled 'large send offload' which is now giving me transfer speeds of 10-11MB p/s. But that still seems quite low in comparison, what do you think?

The "large send offload" setting change is clearly a good idea.

10-11 MB/s is as fast as 100 mbit ethernet will go. So it is worth sorting out why you are not negotiating gigabit ethernet. You might need a support request to your ISP to diagnose it from the router side. Is both the PC and the NAS amber?
