Hi there.
I have the DS1522+ with the 10gbE NIC installed. I have it connected to a router with a 1gbE cable and i also have it connected directly to my PC with the 10gbE.
The problem is that in DSM i can see the two LANS connected with Static IP (that i’ve set up) but the NAS is connecting only with the first IP via Chrome so the transfer speeds i get are 1gbE limited.
How can i make my PC and NAS see each other through the 10gbE?
As i said, i’ve connected the NAS directly to the PC via 10gbE and the NAS to the router via 1gbE.
Do i need a 10gbE switch? Since i’m the only PC accessing the NAS?
Did I miss something?
I think you may need the switch. I have it working with a switch. I am using the Netgear GS110MX. I am not experienced to know enough to say you can have it work without the switch.
I do know in DSM 7.2 under Networking there is a place to put the order of the LAN connections. That could fix it for you as well but I don’t know if that alone will.
So its actually pretty easy to do!
Basically you just want to create a static subnet that both the NAS and the PC’s 10GbE cards are on, and use that IP when connecting in windows file explorer. I cover it in this video:
For windows: if you assigned the NAS to 10.10.10.10 then in windows file explorer you would type \\10.10.10.10 and you would know it has to go down the 10GbE connection, as that is the only place where that IP exists
I also setup a static address and direct connected. 10GB autonegotiates on that card so you dont need a special reversed cable. However one thing I havent sorted out is why I cant connect to the NAS when my mac is also connected to WIFI. I have to turn off WIFI on my macbook to connect to the NAS??
The only reason I could see this being possible is if you setup the static IP on the direct connection on the same subnet as your main LAN. Otherwise the 10.10.10.0/24 subnet should only be accessible via the direct connection. Making wifi irrelevant
Will, so sorry about this, but I’m really struggling getting my DS1621+ to stay connected via 10gbe.
I have done exactly what you’ve said in the video above;
Lan 5 on static IP address; 10.10.10.5 w/ subnet mask of 255.255.255.0
Mac Studio static ethernet port on; 10.10.10.10 w/subnet mask 255.255.255.0
I am also hardwiring my mac studio in to my router via ethernet / thunderbolt adapter.
If I sense that my NAS isn’t giving me the performance it should, I run a disk speed test - it’s always maxing out at 100mbs read/write speed, so I know my computer has decided to connect to my NAS via thunderbolt adapter (or wifi?)
As soon as I unplug the thunderbolt ethernet adapter, it forces my computer to use the 10gbe ethernet cable and I run the disk speed test and get 400mbs read/write speed.
As soon as I plug the thunderbolt/ethernet adaptor in for internet, my mac studio favours that connection rather than the 10gbe connection and gives me 100mbs read/write speed again.
This thunderbolt port uses DHCP, has an IP address of 192.168.x.x and is on subnet mask 255.255.255.0
Is the issue here that the internet is on the same sub mask as my 10gbe card?
When I type in 10.10.10.5 into my browser I can connect to my NAS.
Also, unsure whether this is the problem, but I also use a VPN. No idea where this comes in to the equation.
I am confused.
Thank you so much for your help.
You should use different dedicated subnet between your 10G interface and the Synology 10G connection to avoid this behavior.
An example to connect your macOS to Synology DS1621+:
- macOS LAN (10gb) <---- dedicated LAN cable----> Synology 10gb
- macOS Thunderbolt Adapter <----LAN—> NetworkSwitch <---- InternetRouter / Synology …
For connection 1 define network:
ip macOS = 10.10.10.10 mask 255.255.255.0
ip synology = 10.10.10.5 mask 255.255.255.0
For connection 2 define different network:
ip macOS WLAN / thunderbolt adapter = DHCP (e.g. from 192.168.100.x)
ip synology = 192.168.100.y
If you connect from macOS to Synology - you have to connect to 10.10.10.5 to use the 10G line.
(e.g. Finder → Apple + K → smb://10.10.10.5/…)
But if this is not possible and you network interfaces are sharing the same subnet,
you have to setup the order of your network adapters in macOS.
- click on the top left corner at the apple logo
- select “system settings”
- in the left sidebar choose “network”
- open the action menu by clicking on the 3 dots and select change order network interfaces
Ensure that your 10G interface adapter is listed at the top of the list.
macOS will go through that list and start with the adapter listed on the top …
In the Synology DSM you can open the Ressource-Monitor, then click on “network”.
If you copy big file from or to the Synology, then you can see wich LAN interface is used in on the Synology to receive or sent out the data.
Please also check the speed twice. Once for a copy TO the NAS and another one from the NAS.
In case you are not successfully,
please could you share the following output from your macOS “terminal”
ifconfig -a inet

Hey Will–If I use the technique you describe in your video to connect my MBP to my DS923+ using the OWC TB–>10GBE adapter and the Synology 10GBE card in the NAS, can I then connect the DS923+ to my cable modem using one of the 2 available 1GB ethernet ports on the NAS, or will I need a switch to do this? I already own the OWC 10GBE adapter and I mainly am concerned about having 10GBE connection between the MBP and the NAS for transfer of image files quickly between them. Thanks so much for your help and all your wonderful videos!
Will, I LOVE your videos; I’m SO grateful for this channel!! So I need some help… I’m an utter noob at advanced tech stuff. I just watched a video trying to understand what IP addresses are. So my dilemma… I convinced my parents to go in on a DS920+ with me in the last year. It’s been AWESOME, helpful, and just a layer of peace of mind having local redundancy that I didn’t use to have. I’m a pretty green photographer and hope to grow my business and keep archives on the NAS. I’m kinda worried though that I may have unwittingly f***ed up our NAS and wonder if you or anyone can offer any quick fixes to get back into it? I was trying to do what you did here. But I couldn’t find this video and I watched someone else’s on setting your LAN 2 port to a custom IP address, adding that setting to your laptop, and redirecting your NAS through to that second port and not having it go through the router. I also didn’t know you need the pcie card to direct-connect. Before understanding it all, I programmed a static IP address and subnet mask, got rid of the router portion, I then hit the ‘make default gateway’ box and now I can’t access through SMB or quickconnect or anything. ! Got any pointers on how to fix what I done did? Eek. And thanks.
If you configured a static IP address on the NASs LAN2 port, I assume that the LAN1 port still has a dynamic IP address. Connect that LAN1 to the router and do the same for your PC. Next, use the Synology Assistant application or Synology Web Assistant (HTTP://find.synology.com) to find and connect the NAS. Log into the DSM desktop, open Control Panel, and remove the static IP address for LAN2.
Paul!! I’m so grateful for your response. To clarify, I plug my NAS LAN1 to my router, then do I plug my laptop into my router, or plug my laptop into my NAS LAN2? I tried both and used the Web Assistant and also desktop Synology Assistant. Neither of them retrieved any results on either connection.
I did get a notification when I plugged in my laptop to my router that there was another device using the same IP address as my computer on the network. Maybe that has something to do with it?
Thanks for your help again.
Connect the NAS and laptop to the router. If there is a duplicate IP address, ensure your laptop has a dynamic address, that is not fixed or static.
A duplicate IP address will prevent your NAS from being found.
IT WORKED!!! Thank you SO much Paul!!
I’ve been sold on the 2.5Gig connection instead of 10Gig. To set that up, do I still need to buy a pcie card or just follow the rest of your instructions here and plug in to my NAS?
I am not sure I follow. Can you elaborate? Your NAS has a 1 Gbps LAN.
For sure. Ah, thanks. I just learned that on the DS920+ Fact Sheet. At the time that I posted this, I wasn’t sure the speed of the LAN port.
My goal is to get a fast direct connection via the LAN port to connect for faster backups and maybe working on video projects. As I understand it, to get those speeds, you need to purchase an expansion card.
In this video, Will explains how to upgrade that LAN port to a 10GbE connection. Do you do the same to attain a 2.5 GbE connection, installing a separate 2.5 GbE expansion card? I found another of his videos advocating for the benefits of the 2.5 GbE connection over 10 GbE, and saying 2.5 is plenty big enough.
Again, the DS920+ does not support add-in cards like PCIe. You need the DS923+ or a different model for that.
A ‘direct connection’ is not faster than a connection via a switch with the same speed. This is one of the Internet myths.
An exception is when you have a faster Ethernet adapter in both the computer and the NAS but lack a faster switch.
Regarding 2.5 Gbps Ethernet versus 10 Gbps Ethernet, a 2.5 Gbps connection is much cheaper, and beyond 5 Gbps, you do not gain much. In other words, you do not quickly saturate a 10 Gbps connection.
Great I appreciate it. So no putting a pcie card in my NAS. And definitely don’t need the 10 Gigabit connection.
I don’t actually know what a switch is but have heard it referenced a ton. What is a switch? Is that something I have?
So since my LAN ports are only 1 Gigabit LAN ports, my understanding is that there is no increasing the speed to 2.5 or 5 Gigabit?
Thanks
Do you have an internet modem, a.k.a. router? It might have several LAN ports. That part of the device is the switch.
That is correct.
