[iOS/Android] The ScanSnap and the mobile device cannot be connected via Wi-Fi

Updated
1. Check the ScanSnap

Is the Wi-Fi switch of the ScanSnap turned off?

Turn on the Wi-Fi switch of the ScanSnap.

Is the Wi-Fi indicator lit or flashing in orange?

  • The signal between the wireless access point and the ScanSnap is weak, or there may be some signal interference.

    Move the ScanSnap and the wireless access point to different locations.

    • Move the ScanSnap closer to the wireless access point.

    • Move the ScanSnap and the wireless access point away from the following items:

      • Obstacles that may block the signal (for example, walls and metal boards)
      • Devices that may cause signal interference (for example, microwaves and cordless phones) and wireless devices

    • Change the direction of the ScanSnap.

    Also, communication in certain wireless channels may become unstable due to signal interference such as noise.

    Change the value of the wireless channel on the wireless access point.

  • Use ScanSnap Wireless Setup Tool to check whether the default Wi-Fi settings are restored.

    For details about how to start ScanSnap Wireless Setup Tool, refer to [Windows/macOS] How can I start the ScanSnap Wireless Setup Tool?.

TIP

Is the ScanSnap being used by another computer or mobile device?

Connect the ScanSnap after you finish using it with another computer or mobile device.

2. Check the network

Is the ScanSnap connected to the wireless access point?

Check the following and take appropriate measures to solve the problem.

Is the wireless access point turned on? Alternatively, are there any errors or malfunctions on the wireless access point?

Turn on the wireless access point.

If the wireless access point is turned on, restart the wireless access point and then check that there are no errors or malfunctions on the wireless access point.

For details about wireless access point errors, refer to the manual of your wireless access point.

TIP
Have you connected the ScanSnap to a wireless access point?

Connect the ScanSnap to a wireless access point by using ScanSnap Wireless Setup Tool.

For details, refer to the following:

For details about how to start ScanSnap Wireless Setup Tool, refer to [Windows/macOS] How can I start the ScanSnap Wireless Setup Tool?.

Are the network name (SSID), security protocol (authentication method), encryption method, and security key configured correctly?

The settings for the ScanSnap such as the network name (SSID), security protocol (authentication method), encryption method, and security key need to match with the settings for the wireless access point.

Check the Wi-Fi settings for the ScanSnap, and configure again if necessary.

For details about how to check the Wi-Fi settings, refer to the following:

For details about how to start ScanSnap Wireless Setup Tool, refer to [Windows/macOS] How can I start the ScanSnap Wireless Setup Tool?.

Note that if you do not know the network name (SSID) or security key of the wireless access point, refer to the manuals of the wireless access point, or contact the manufacturer.

If the security protocol for the network name (SSID) is "WPA3", the ScanSnap cannot be connected. Connect the ScanSnap to the wireless access point using "WPA2" as the security protocol.

Ask the manufacturer of the wireless access point whether the security protocol is "WPA2".

Are the ScanSnap and wireless access point distant from each other? Also, is there anything that may block the signal (such as walls and metal boards), or an electromagnetic source?

The signal between the wireless access point and the ScanSnap is weak, or there may be some signal interference.

Check the signal status by using ScanSnap Wireless Setup Tool.

For details, refer to the following:

For details about how to start ScanSnap Wireless Setup Tool, refer to [Windows/macOS] How can I start the ScanSnap Wireless Setup Tool?.

If the signal status is not fine, move the ScanSnap and the wireless access point to different locations.

  • Move the ScanSnap closer to the wireless access point.

  • Move the ScanSnap and the wireless access point away from the following items:

    • Obstacles that may block the signal (for example, walls and metal boards)
    • Devices that may cause signal interference (for example, microwaves and cordless phones) and wireless devices

  • Change the direction of the ScanSnap.

Also, communication in certain wireless channels may become unstable due to signal interference such as noise.

Change the value of the wireless channel on the wireless access point.

 

3. Check the wireless access point

Have you configured any communication authorization settings on the wireless access point?

If the settings are configured in the ways below on the wireless access point, follow the solutions accordingly.

  • Communication between wireless devices is disabled (for example, because of a privacy separator function or a port separator function)

    Enable communication between wireless devices on the wireless access point.

  • When the SSID broadcast, such as ANY connection, is disabled

    Enable the SSID broadcast on the wireless access point. Otherwise, configure the Wi-Fi settings manually.

  • When the protocol filter function is configured

    Configure the protocol on the wireless access point.

  • When the stealth function is configured

    Disable the stealth function, and then configure the Wi-Fi settings again using the WPS function. Otherwise, configure the Wi-Fi settings manually.

  • When MAC address filtering is configured

    Set the MAC address for the ScanSnap on the wireless access point, and then configure the Wi-Fi settings again.

In addition, the set channel may be used with another wireless access point.

In this case, change the value of the wireless channel on the wireless access point.

For details about the settings of the wireless access point, refer to your wireless access point manual.

Are you using a public wireless LAN service?

In a public wireless LAN environment, the ScanSnap cannot be connected from a mobile device because the privacy separator function is usually set to enabled.

Use the ScanSnap in Direct Connect mode without a wireless access point.

If you connect the ScanSnap to a public wireless LAN by mistake, the ScanSnap cannot be used in Direct Connect mode in the environment. Perform one of the following:

  • Delete unnecessary wireless access points by using ScanSnap Wireless Setup Tool.

  • Switch to the Direct Connect mode manually.

For details, refer to the following:

For details about how to start ScanSnap Wireless Setup Tool, refer to [Windows/macOS] How can I start the ScanSnap Wireless Setup Tool?.

4. Check the mobile device

Are there any errors with the mobile device or ScanSnap Home installed on the mobile device?

Refer to the screens of the mobile device and ScanSnap Home installed on the mobile device as well as the manuals to take appropriate measures.

5. Check other possible causes

Are there network security restrictions?

Contact the network administrator.

Contact your network administrator if IEEE 802.1X authentication is used.

Check the following with your network administrator:

  • Whether the Wi-Fi settings are the same as the settings on the authentication server

  • Whether the network environment for the authentication server is normal

  • Whether the authentication server and the wireless access point are connected correctly

  • Whether the certificate is valid

    Example: Whether the certificate has not been revoked or has not been expired

  • Whether the CN (CommonName) for the certificate is within 64 bytes if [EAP-TLS] is selected for the authentication method.

If the problem still persists after appropriate measures are taken for all check items, refer to the following:
