Slow NAS when connected to Superhub

oli356 · 26 Dec 2014 at 14:40

Hi all,

I recently purchased my first ever NAS - a Synology DS215j

Its using a wired connection to my Virgin Superhub as is my PC

When reading/writing to the NAS though the speeds never go above 12 MBs. I tried plugging my laptop directly into the NAS and the speeds were over 40 MBs. Based on this I know that the cable is working correctly.

What I don't understand though is why when I plug into the router do the speeds become terrible... anybody got any suggestions? :eek:

If you're seeing 12MBps it's probably a 100Mbps connection.

Ether the Superhub doesn't support Gigabit or there's something forcing it down to 100Mbps (wiring fault?).

That crossed my mind after I made the post but the NAS NIC on the status is reporting as Full Duplex 1000 Mbps and the Superhub is Gigabit also.

How is the device you're testing the speed with connected to the Superhub? The connection needs to be Gigabit end-to-end.

Ahhh.. I forgot I had a D-Link DIR-615 going to the Superhub and this was broadcasting the wireless SSID. My PC was also plugged into it....

It was the bottleneck at 100 Mbs -.- all fixed now.

Thanks
