If your Toast POS is showing a network error or switching into Offline Mode unexpectedly, this guide walks you through the fastest ways to get Toast back online. These fixes come from real restaurant issues—slow Wi-Fi, router problems, KDS drops, and multi-station sync issues.

Common Causes of Toast Network Errors

• Weak or unstable Wi-Fi signal
• Router or access point overload
• Toast terminals too far from the router
• Guest Wi-Fi instead of secured network
• Interference from walls, appliances, or metal equipment
• Outdated Toast POS app version
• Temporary Toast network service issues

How to Fix Toast Network Errors

1. Restart the Toast POS Terminal

The quickest fix for random network drops.

• Hold the power button
• Select Restart
• Allow the device to fully reboot
• Reconnect to Wi-Fi

If the terminal is freezing along with network errors, see our Toast POS Frozen guide.

2. Reconnect to the Correct Wi-Fi Network

Toast devices must be on your secured, business Wi-Fi—not guest Wi-Fi or public networks.

• Swipe down → open Wi-Fi settings
• Connect to your correct secure SSID
• Forget the guest network to avoid auto-switching
• Reconnect Toast POS and retry

3. Check Your Signal & Router Placement

Weak signal is the #1 reason Toast devices randomly drop offline.

• Move the terminal closer to your router or access point
• Avoid placing Toast devices near metal walls, freezers, ovens, or tall POS counters
• Keep the router elevated—not on the floor or under counters

If your KDS screens are also lagging or dropping orders, see our Toast KDS Not Working guide.

4. Restart Your Router & Access Points

Restaurants with multiple devices often overload routers during peak hours.

• Restart your router
• Restart any additional access points
• Wait 1–2 minutes for full reboot
• Reconnect Toast terminals

5. Update the Toast POS App

Outdated Toast software can cause offline mode glitches and sync failures.

• Restart your terminal or tablet
• Open the app manager
• Search for Toast POS
• Tap Update if available

6. Verify Toast Offline Mode Settings

If Offline Mode doesn’t activate properly, check your configuration:

• Log into the Toast Dashboard
• Go to Payments
• Ensure Offline Mode is enabled for your merchant account
• Retry processing a payment

7. Reduce Network Interference

Interference from kitchen equipment or crowded Wi-Fi channels can cause Toast devices to disconnect.

• Keep devices away from microwaves, metal walls, freezers, etc.
• If possible, switch your Wi-Fi channel to a less crowded one
• Ask staff to avoid streaming or using bandwidth-heavy apps

8. Reboot the Entire Toast System (Last Resort)

If nothing else works, restart everything:

• All Toast terminals
• Routers and access points
• KDS screens
• Network switches

When to Contact Toast Support

If Toast continues showing network errors after trying these steps, you may be dealing with:

• Misconfigured merchant network settings
• Hardware issues with the terminal
• A Toast-side server or connectivity outage
• Access point or router failure
