MICROS terminals dropping offline? Orders stop sending, printers fail, and payments won’t go through. Most disconnects point to network or server connectivity issues.
This guide shows the fastest ways to restore a reliable connection during service.

What Causes MICROS to Disconnect?
- Loose ethernet cables or weak Wi-Fi signal
- Server offline or unable to communicate
- IP conflicts between terminals
- Network congestion (too many devices on Wi-Fi)
- KDS/printers routing blocked when connection drops
- Outdated switch or router hardware
Pro tip: If all stations disconnect at the same time, the problem is almost always the server or router — not individual terminals.
How to Fix MICROS Network Drops
1. Restart the Terminal’s Network Session
A simple restart refreshes the network handshake between server and terminal.
- Log out and restart MICROS device
- Test ordering and printing again
2. Check Cables or Wi-Fi Signal Strength
Any interruption can break routing — especially under high demand.
- If wired: ensure ethernet is securely connected
- If wireless: move closer to access point
- Reduce interference (microwaves, walls, crowded bands)
Pro tip: POS stations should be wired, not Wi-Fi, whenever possible.
3. Restart the Router/Switch During a Slow Period
Network hardware may need a refresh to clear errors or stuck connections.
- Restart router and network switch
- Verify activity lights are normal and stable
4. Confirm Server Connectivity
If the server goes offline, terminals cannot validate orders or payments.
- Check server health and uptime
- Reboot if connectivity is unstable
5. Look for IP Conflicts
Two devices sharing the same IP can cause random disconnects.
- Ask your IT tech to verify static IP assignments
- Ensure DHCP isn’t taking over station addresses
When to Contact MICROS Support
- Multiple terminals disconnect repeatedly
- Server goes offline regularly
- Kitchen routing fails every time network drops
- You suspect failing cabling or switch hardware
