How do I look at the Network settings on the NAS to see if it is Gbit?

Go to the network tab in the web ui.  You'll see a bandwidth indication at the bottom of the list for your network adapter (under ipv6).  The adapter you aren't using will be grayed out.  Note you shouldn't be using both adapters unless you've set up link aggregation.

 

Also - if your network doesn't use ipv6 (most don't), then disable it in the NAS.  That can also help speed things up.  Click on the settings wheel next to your network adapter, then click on the ipv6 tab.  You can disable ipv6 using the pulldown menu next to "configure".

Also, I don't know what jumbo frames are.

In network parlance, "frames" are what carry the packets.

 

Standard ethernet has a max packet size of 1500 bytes.   Jumbo frames (which carry packets > 1500 bytes) are supported by some devices.

 

Setting them up requires some manual configuration on multiple devices (at least your Mac, PC,and the NAS).  In some cases they can speed up transfer speeds, but they can also break things.  Personally I don't use them.

Thanks for the tips. Very helpful.

The network tab shows 1 Gbps, so the cabling must be okay.

When I chose "disable" for ipv6, the message says all communication will be lost, so I left it alone.

Regarding jumbo frames, I think you're right. I would rather not mess with those settings.
