# Wi-Fi clock-in

> Learn how to set up Wi-Fi clock-in for DingTalk Attendance by matching the router's MAC address. Enter the full MAC address and find answers to common issues, such as iOS clock-in failures and clock-in across multiple Wi-Fi networks.

## 1. Overview

Wi-Fi clock-in matches the MAC address of the Wi-Fi router with the MAC address of the network the employee connects to. Enter the **complete MAC address**. For the pros and cons of each clock-in method, see [**Differences between clock-in methods**](/attendance/clock-in-methods-comparison).

## 2. Use cases

## 4. FAQ

<AccordionGroup>
  <Accordion id="q1" title="Why can't iOS devices use Wi-Fi clock-in?">
    A single Wi-Fi network may have multiple MAC addresses. iOS devices identify the network by the **Wi-Fi** MAC address. We recommend that the Admin use an Android phone to add the MAC address of each Wi-Fi network.
  </Accordion>

  <Accordion id="q2" title="How do I clock in across multiple Wi-Fi networks?">
