Can't Find Your Synology on the Network? Here Are All the Ways to Track It Down

Finding your Synology NAS on a network requires one of several detection methods depending on your router setup, OS, and whether the device has been configured before. Synology provides dedicated tools that scan the local network for NAS devices, but standard OS network browsing also works when SMB and network discovery are properly configured.

Part 1. Method 1 — Use Synology Web Assistant

Synology Web Assistant is the fastest and most reliable method for finding a Synology NAS on any network. It runs in the browser without requiring any installed software.

How to use Web Assistant:

1. Open a browser on a computer connected to the same network as the NAS
2. Navigate to find.synology.com
3. Web Assistant scans the local subnet and lists all detected Synology devices
4. Click your device to open DSM (DiskStation Manager) setup or login

💡 Tip: Web Assistant works during initial setup before DSM is installed, making it the recommended starting point for both new and existing devices. Make sure you're on the same Wi-Fi or LAN segment as the NAS — it won't detect devices across different subnets.

Part 2. Method 2 — Use Synology Assistant Desktop App

Synology Assistant is a lightweight desktop application that scans the local network for Synology NAS devices and displays them in a list with their IP address, MAC address, DSM version, and status.

Installation and usage:

1. Download Synology Assistant from the Synology Download Center
2. Select your NAS model and choose "Desktop Utilities" to find the Synology Assistant package
3. Install and launch the application
4. Click "Search" — detected Synology devices appear in the list within seconds
5. Double-click an entry to open DSM in your browser

🗣️ r/synology user: "Web Assistant didn't detect mine but Synology Assistant found it straight away. Turned out the browser had a firewall exception issue. The desktop app bypassed it."

Synology Assistant is particularly useful when the web-based tool fails, as it uses a slightly different discovery protocol that can bypass certain browser restrictions.

Part 3. Method 3 — Find the IP via Your Router Admin Panel

If both Synology tools fail, finding the NAS IP address through your router is reliable because the router always tracks every connected device.

Steps:

1. Open a browser and go to your router's admin IP (typically 192.168.1.1 or 192.168.0.1)
2. Log in with your router credentials (often on a label on the router itself)
3. Look for a section called "Connected Devices," "DHCP Client List," or "LAN Clients"
4. Find the device named "DiskStation," "SynologyNAS," or matching your NAS model name
5. Note the IP address and type it directly into your browser (e.g., http://192.168.1.100:5000)

💡 Tip: Assign a static (reserved) IP to your Synology NAS in the router's DHCP settings using its MAC address. This prevents the IP from changing on router restarts, making future access consistent.

Part 4. Method 4 — Use a Network Scanner

If the Synology tools and router admin method don't work, a network scanner can detect any device on the subnet including the NAS.

Popular options:

• Angry IP Scanner (Windows, Mac, Linux): Free, scans IP ranges and shows hostnames
• Advanced IP Scanner (Windows): Shows manufacturer, MAC address, and shared folders
• LanScan (Mac App Store): Lightweight and fast for macOS users

Scan the subnet your devices are on (e.g., 192.168.1.0/24). Look for entries with "Synology" in the hostname or manufacturer field, or for MAC addresses beginning with 00:11:32 (Synology's registered OUI prefix).

🗣️ r/homelab user: "Angry IP Scanner is my go-to whenever I can't find a device. Scanned my subnet in 10 seconds and found the NAS at an IP I never would have guessed."

Part 5. Troubleshoot Network Discovery on Windows and Mac

When the NAS is detected by IP but doesn't appear in Windows File Explorer or macOS Finder, SMB settings are usually the cause.

On Windows:

• Open Control Panel → Programs → Turn Windows features on or off
• Ensure "SMB 1.0/CIFS File Sharing Support" is enabled (or SMB 2.0/3.0 depending on DSM version)
• Open File Explorer and type \\[NAS IP address] in the address bar (e.g., \\192.168.1.100)
• Enable Network Discovery: Control Panel → Network and Sharing Center → Change advanced sharing settings → Turn on network discovery

⚠️ Important: Do not permanently enable SMB 1.0 on Windows unless specifically required for an older Synology DSM version. SMB 1.0 has known security vulnerabilities. DSM 6.0 and later support SMB 2.0 and SMB 3.0 by default.

On Mac:

• Open Finder → Go menu → Connect to Server
• Enter smb://[NAS IP address] (e.g., smb://192.168.1.100)
• Enter your DSM credentials to mount the shared folder

💡 Tip: On macOS Ventura and later, Finder's network discovery relies on Bonjour and mDNS. If the NAS doesn't appear in the Finder sidebar, manually connecting via Go → Connect to Server is the most reliable alternative.

Part 6. Recover Lost Files From Synology Drives With Ritridata

If a Synology drive was removed and connected directly to a Windows or Mac computer — and files were accidentally deleted or the drive shows as unreadable — Ritridata can scan it for recoverable data.

Ritridata supports recovery from external HDDs, SSDs, and USB drives formatted with common file systems. Connect the Synology drive via USB enclosure or SATA adapter to your computer, then run a scan.

Step 1 — Select the drive/location

Step 2 — Run a safe scan

Step 3 — Preview and recover to another drive

FAQ

Q: Why can't I find my Synology NAS on the network after a power outage? A: The NAS may have received a new DHCP IP address from the router after power cycling. Use Web Assistant or Synology Assistant to rediscover the new IP, then consider assigning a static IP to prevent this recurring.

Q: Does Synology Web Assistant work from outside my home network? A: No. Web Assistant only works on the same local subnet as the NAS. For remote access, enable Synology QuickConnect in DSM, which allows browser-based access from anywhere.

Q: My Synology shows in Synology Assistant as "Not Installed" — what does that mean? A: It means the device is detected on the network but DSM (the operating system) has not yet been installed. Click the entry and follow the DSM installation wizard to complete setup.

Q: Can I access Synology DSM without knowing the IP address? A: Yes. If QuickConnect is enabled, visit QuickConnect.to/yourID to access DSM from any browser. During initial setup, use Web Assistant at find.synology.com as an alternative.

Q: Why does my Synology disappear from the network after a few hours? A: This often indicates a DHCP lease renewal issue where the router assigns a new IP. Reserve a static IP for the NAS in your router's DHCP settings using the NAS's MAC address to resolve the problem permanently.

Q: Is it safe to plug a Synology drive directly into a Windows PC? A: Synology drives typically use the Btrfs or ext4 file system, which Windows cannot read natively. Connecting the drive to Windows will not damage it, but Windows may show the drive as unformatted. Use a Linux-based tool or data recovery software to access the data.

Q: What port does Synology DSM use? A: DSM uses port 5000 for HTTP and port 5001 for HTTPS by default. If accessing by IP fails, try http://[IP]:5000 explicitly in your browser.
