Sony SmartEyewear 4 WiFi Connection Fix

Introduction

Sony SmartEyewear 4 has become a popular choice for people who want hands‑free access to media, navigation and information.
A common frustration, however, is that the glasses stop connecting to Wi‑Fi or simply never find the network.
The good news is that most connectivity problems can be solved with a few deliberate steps.
This guide walks you through the troubleshooting process, from the simplest checks to a factory reset, so that you can enjoy uninterrupted Wi‑Fi on your SmartEyewear 4.

Understanding Wi‑Fi on SmartEyewear 4

The SmartEyewear 4 uses a 2.4 GHz Wi‑Fi interface.
It does not support the 5 GHz band, so any network that is exclusively 5 GHz will be invisible to the glasses.
The device also relies on the Sony SmartEyewear app (available on iOS and Android) to pair the glasses with your phone and configure Wi‑Fi settings.
Because the glasses themselves have a limited on‑screen interface, most changes must be made through the app or the router.

Common Connection Issues

Recognizing the symptom helps target the right fix.

Preliminary Checks

1. Verify the Network Band
   Make sure the router is broadcasting a 2.4 GHz network.
   If you only have a dual‑band router, confirm that the 2.4 GHz SSID is active.

2. Check the SSID and Password
   The glasses must connect to the same SSID and use the correct password.
   If you recently changed the network password, update the SmartEyewear app.

3. Confirm Router Compatibility
   Some routers use 802.11n or 802.11ac with channel settings that may not be ideal for older devices.
   Setting the router to “mixed” mode (b/g/n) often improves compatibility.

4. Keep the Glasses and Phone Near the Router
   A weak signal can lead to intermittent failures.
   Place the glasses and phone close to the router during initial setup.

Step 1: Reset Wi‑Fi Settings on the Glasses

The SmartEyewear 4 does not have a physical “reset” button, but the Wi‑Fi settings can be cleared through the app.

• Open the Sony SmartEyewear app.
• Tap the menu icon and select Device Settings.
• Choose Wi‑Fi and press Forget on any stored networks.
• Re‑enter your Wi‑Fi SSID and password.

After this, attempt to connect again.
If the connection fails, proceed to the next step.

Step 2: Update Firmware on the Glasses and App

Out‑of‑date firmware is a frequent culprit for connectivity glitches.

• In the app, go to Device Settings → Firmware Update.
• If an update is available, download and install it.
• Make sure the phone stays connected to the Wi‑Fi during the update.

While the firmware updates, the app may prompt you to keep the glasses within close proximity.

Step 3: Adjust Router Settings

Router misconfigurations can prevent SmartEyewear from seeing the network.

• Set Channel to 1, 6, or 11 – these are the non‑overlapping channels for 2.4 GHz.
• Disable MAC Filtering – some routers block unknown devices by default.
• Turn Off Guest Network Isolation – this isolates devices on the guest SSID.
• Enable WPS – if your router supports WPS, you can use it to pair the glasses without entering a password.
• Limit Max Connections – a very high number of simultaneous connections can degrade performance.

After adjusting, reboot the router and try connecting again.

Step 4: Reinstall the Sony SmartEyewear App

Sometimes the app itself can become corrupted.

• Delete the Sony SmartEyewear app from your phone.
• Restart the phone.
• Download the latest version from the App Store or Google Play.
• Re‑pair the glasses via the app’s onboarding process.

This often clears hidden configuration files that interfere with Wi‑Fi.

Step 5: Reboot Devices

A simple reboot can clear temporary glitches.

• Turn off the SmartEyewear 4 by holding the power button until the LED flashes red.
• Restart the phone.
• Power on the glasses again.
• Open the app and attempt a connection.

Step 6: Use 2.4 GHz vs 5 GHz

If you have a dual‑band router, the SmartEyewear 4 will not detect the 5 GHz band.

• Log into your router’s web interface.
• Separate the 2.4 GHz SSID from the 5 GHz SSID (e.g., “Home‑2.4G” vs “Home‑5G”).
• Connect the glasses to the 2.4 GHz SSID.

If you only see a single SSID and it is 5 GHz, you will need to enable the 2.4 GHz band.

Step 7: Factory Reset the Glasses

When all else fails, a factory reset will clear all configurations.

1. Open the App – go to Device Settings → Reset.
2. Choose “Factory Reset” – confirm the prompt.
3. Wait – the glasses will power down and restart automatically.
4. Re‑pair – follow the initial pairing steps in the app.

Warning: A factory reset erases all stored Wi‑Fi credentials, paired devices, and any downloaded content.

Step 8: Contact Sony Support

If none of the above steps resolve the issue, it may be a hardware fault.

• Visit the Sony SmartEyewear support page.
• Gather your serial number (found on the back of the glasses or in the app under Device Information).
• Submit a support ticket with a detailed description of the steps you have already taken.
• Keep a photo or video of the error message (you can take a screenshot on the phone).

Sony’s support team can guide you through advanced diagnostics or arrange a repair/replacement.

Frequently Asked Questions

• Can I connect SmartEyewear 4 to a VPN?
  The glasses do not support VPN natively.
  However, if your phone is on a VPN, the glasses may inherit the connection, though performance can degrade.

• What if the Wi‑Fi password has special characters?
  The SmartEyewear 4 app accepts most characters, but avoid spaces at the beginning or end of the password.
  Enter the password exactly as shown on the router.

• Will turning on WPA3 fix the problem?
  Some older devices struggle with WPA3.
  Set the router to WPA2/WPA3 mixed mode if you encounter issues.

• Is there a way to monitor Wi‑Fi signal strength on the glasses?
  The app displays a connection indicator and signal strength bar.
  If the bar remains at 0 % despite being in range, the network is likely blocked or incompatible.

Conclusion

A reliable Wi‑Fi connection is essential for the full SmartEyewear 4 experience.
By systematically checking the network band, resetting Wi‑Fi settings, updating firmware, adjusting router configurations, reinstalling the app, and, if necessary, performing a factory reset, you can resolve most connectivity problems.

If the issue persists after following these steps, Sony support is ready to help.
With the right troubleshooting approach, your SmartEyewear 4 will stay connected, letting you enjoy hands‑free browsing, navigation, and entertainment wherever you go.
