Can't reach your NAS at all?
Before diving into complex fixes, work through these quick checks. 90% of NAS disappeared problems are solved in under 2 minutes.
Step 1The 60-second check
# Step 1: Is the NAS actually on? Check the power LED.
# Step 2: Find your NAS IP
$
arp -a
? (192.168.1.10) at 00:11:32:... [ether] ← your NAS
# Step 3: Can you ping it?
$
ping 192.168.1.10
64 bytes from 192.168.1.10 — time=1.2ms ← online
Request timeout ← not reachable
Lost the IP? Log into your router (usually 192.168.1.1) and check the DHCP client list. Your NAS will be listed there with its current IP address.
Step 2Give your NAS a permanent IP
If the IP keeps changing every time you restart, fix it once:
1. Log into your router → find DHCP Reservations or Static DHCP
2. Find your NAS in the list
3. Click Reserve or Bind — done
Alternative: set static IP on the NAS itself
Synology: Control Panel → Network → Network Interface → Edit
TrueNAS: Network → Interfaces → Edit
Unraid: Settings → Network Settings
Windows shares
SMB / Windows share keeps disconnecting
SMB disconnections are usually caused by Windows power-saving or a protocol version mismatch. Here is how to fix both.
Step 1Fix Windows 11 power-saving disconnections
Open PowerShell as Administrator (right-click Start → Terminal (Admin)):
# Disable SMB power-saving
PS>
Set-SmbClientConfiguration -EnableBandwidthThrottling 0 -EnableLargeMtu 1
# Never disconnect idle sessions
PS>
Set-SmbClientConfiguration -SessionTimeout 0
# Confirm SMB1 is disabled (it causes instability)
PS>
Get-WindowsOptionalFeature -Online -FeatureName SMB1Protocol
State : Disabled ← good
Step 2Mount SMB share from Linux with the right options
# Install cifs-utils if not present
$
sudo apt install cifs-utils
# Mount the share — vers=3.0 fixes most issues
$
sudo mount -t cifs //192.168.1.10/ShareName /mnt/nas -o username=admin,vers=3.0,uid=1000
# Make it permanent — add to /etc/fstab
//192.168.1.10/ShareName /mnt/nas cifs credentials=/etc/nas-creds,vers=3.0,uid=1000,nofail 0 0
