Drives & data

NAS drive not accessible on the network

A NAS that won't connect is usually a network, permissions, or power issue rather than a failed drive, and checking the network path first saves time.

Symptoms

  • NAS doesn't appear in File Explorer's Network section
  • 'Network path was not found' or similar error
  • Can access the NAS from one device but not another
  • NAS's own web interface won't load either

Likely causes

  • CommonNAS lost its network connection or IP address changedRouters can reassign IP addresses, breaking saved shortcuts.
  • CommonNAS or router was restarted and needs time to reinitializeSome NAS devices take a few minutes to fully boot and share drives.
  • PossibleNetwork discovery or file sharing settings turned off on the computerWindows can silently disable discovery on 'public' networks.
  • PossibleLogin credentials for the NAS share have changed or expiredA shared login can stop working after a NAS software update.
  • PossibleActual drive failure inside the NASIf the whole unit won't respond, including its web interface, it may be a hardware fault.

What to do

  1. Confirm the NAS is powered on and its status lights show normal operation.
  2. Try accessing the NAS by typing its IP address directly (like \\192.168.1.50) instead of its name.
  3. Check the router's connected devices list to find the NAS's current IP address.
  4. On the computer, turn on Network Discovery and File and Printer Sharing in Network settings.
  5. Try logging into the NAS's web interface directly to see if it responds at all.
  6. Restart the NAS and router if neither shows signs of a working network connection.
  7. If the web interface is also unreachable, treat it as a NAS hardware issue rather than a network problem.

When to call a pro

If the NAS itself won't respond even locally and holds important data across multiple drives, get a NAS/data recovery specialist involved rather than experimenting further.
