Common Causes of Toast Tablet Sync Issues
- Tablets on different Wi-Fi networks
- Weak Wi-Fi signal or interference
- Router or access point overload
- Outdated Toast POS app version
- Device crash or low memory
- KDS or other terminals offline
- Temporary Toast service sync delay
How to Fix Toast Tablet Not Syncing
1. Confirm the Tablet Is on the Correct Wi-Fi Network
All Toast devices must be on the same secured network to sync properly. Guest networks break syncing.
- Swipe down → open Wi-Fi settings
- Connect to your secure business network
- Forget guest networks completely
- Reconnect and check syncing again
2. Restart the Toast Tablet
A quick restart fixes most sync failures caused by app glitches or background processes.
- Hold power button → choose Restart
- After reboot, reopen Toast POS
- Check if orders sync across devices
If the tablet was also freezing, see our Toast POS Frozen guide.
3. Check If Other Toast Devices Are Offline
Sync issues often start when a single terminal or KDS screen drops offline.
- Check if the KDS is slow or missing orders
- Check if another register is offline
- Restart any devices that aren’t updating
If your kitchen screens are also delayed or losing orders, see our Toast KDS Not Working guide.
4. Restart Your Router & Access Points
Restaurants with multiple devices often overload their router during peak hours. A reboot clears congestion.
- Restart the router
- Restart access points
- Wait 1–2 minutes for full reboot
- Reconnect Toast devices
5. Update the Toast POS App
Outdated versions can cause delayed syncing and broken communication between stations.
- Restart the device
- Open the device app manager
- Search Toast POS
- Tap Update if available
6. Move the Tablet Closer to Your Router
Walls, freezers, metal, and distance all weaken Toast’s Wi-Fi performance.
- Move within 10–20 feet of the router/AP
- Avoid metal counters or equipment
- Ensure access points cover the full service area
7. Clear Toast App Cache (If Supported)
This helps if the app is glitchy or slow to update.
- Settings → Apps
- Select Toast POS
- Storage → Clear Cache
Do NOT clear “App Data” unless Toast support instructs you to, as it resets local settings.
8. Reboot the Entire Toast System (Last Resort)
If syncing is broken across multiple devices, restart everything together:
- All Toast tablets/registers
- KDS screens
- Routers & access points
- Network switches
When to Contact Toast Support
Contact Toast if syncing issues continue after these steps. You may be dealing with:
- Misconfigured network settings
- Merchant account sync problems
- Hardware or AP coverage issues
- Temporary Toast service outages
