# Network Issues

> Diagnose and resolve internet, LAN, and offline-mode connectivity problems.

DishInk keeps running through network outages, but persistent connectivity issues degrade the experience. This page walks through diagnosing and fixing them.

## Overview

DishInk's three-tier resilience:

1. **Cloud** — normal operation.
2. **LAN** — if internet drops, devices talk over the local WiFi.
3. **Local Storage** — if LAN drops, orders save on-device and sync when reconnected.

Service never stops — but sluggish or intermittent networks still cause bad customer experience.

<Note>
  DishInk indicates connectivity mode in the status bar: Cloud, LAN, or Local. During Local mode, orders queue for sync.

## Tips & best practices

<Tip>
  Use a business-grade dual-band router with QoS enabled. Consumer-grade routers fail under 30+ concurrent devices.
</Tip>

## Common mistakes

<Warning>
  Do not put POS terminals on guest WiFi. Signal contention causes stuttering and dropped orders.
</Warning>
