How to fix UGREEN NAS access issues over Ethernet Mac Studio?

I recently bought a UGREEN NASync DH4300 Plus and set it up by plugging it into my router. The web access worked great for the setup and all went well with no issues.


However, moving large files to the NAS was painfully slow over wifi so I decided to connect the NAS directly to my Mac via Ethernet cable.

Now I can connect and see the ‘server’ in the finder and transfer files to it. But I can’t access the server via the web page (find.ugnas.com).

how to setup the IP?






I was read the article but I can't repay to them

how to setup DHCP-assigned addresses, though static addresses?
  1. You can't have it both ways. It's either static, or DHCP assigned.
  2. The NAS and the Mac can't have the same IP address. The screen shots show the Mac having the same address as the NAS. This is wrong and will of course cause issues.
  3. You can set up the Mac to act as a DHCP server so it hands IP addresses to directly connected devices such as the NAS by enabling Internet Sharing in System Settings.
  4. There is no way to configure static addresses on the Mac since it lacks the "router" panel. You would need to configure a static address directly on the NAS first, while you can connect to it on the network. This will instantly sever the network connection to the NAS though. You would then connect it directly to the Mac instead of through the router, and if the Mac is set to the same IP address range but a different IP, then you should be able to see the NAS and its config page using the address you gave it.

You will pick either the use of DHCP, or pick static (fixed, manual) IP address.


DHCP picks an address from its pool and hands it to the client. For static IP, the IP addresses you choose and manually assign to the client (NAS or whatever else) should be outside the DHCP pool, and must not conflict with any other IP clients in use.


How to set up your local DHCP server and clients depends on your DHCP server which is presumably available in your router, and how the NAS can acquire an address in the NAS documentation.


Check the documentation for your router and your NAS.

I'm going to assume three things here. Please correct me if I assume wrongly:

  • Your Mac is situated such that it cannot directly connect to your router by Ethernet ... correct?
  • Your wireless router or wireless access point is situated such that your Mac is not getting a strong signal, and more importantly, a high data transfer rate for its connection ... correct?
  • Your NAS does not natively support Wi-Fi (most don't) ... correct?


When you moved your NAS, so that it can be directly connected to the Mac by Ethernet, the NAS no longer is accessible from the Internet ... and why you can't access it via the Internet nor locally via a web browser. That's because it is no longer connected to your local network ... only to your Mac. Your NAS must have a local IP address assigned to it. Typically, that would be from the DHCP service provided by your local network router.


If I assumed correctly that where your Mac & router are not near each other, you are basically left with having to use a Wi-Fi connection between the Mac & the router, AND that this NAS needs to be directly connected to the same router by Ethernet.


Alternately, you would need to acquire a local mass storage device that you can connect directly to your Mac for file storage ... but not have a web-based interface to it.

Typical would be ethernet cable to your router, from the Mac and separately from the NAS.


But the speed expected with all that depends on your Ethernet speeds, and your Wi-Fi speeds. And your NAS I/O speed.


It would be more usual to run DHCP-assigned addresses, though static addresses can work.


Whether the NAS is slow or painfully slow depends on various factors, such as the network connection speed, whether the Wi-Fi and wired network is correctly configured, and on details such as whether the HDDs are in RAID 5 or the perception of slowness can arise from HDDs being vastly slower than SSDs.


Here is why a hard disk is so much slower than an SSD — thismin the context of an iMac with HDD — and writes to a RAID-5 HDD NAS are even slower:


You’re going to get to learn more about IP network configurations, and about that UGREEN NAS.
