Hi@bkmeneguello,
EX220 is a customized device specifically designed for local Service Providers. Its software is tailored to meet the unique requirements of these providers, ensuring alignment with their specific needs. While our technical support team is adept at providing general guidance and suggestions for products with standard, generic firmware. However, due to the specialized nature of the firmware on your device, our ability to provide troubleshooting may be limited.
We can certainly offer some troubleshooting tips that may help resolve your issue. Please consider the following:
- Change SSID of guest network for a try;
- Do not select 'Allow Guests to Access Each Other' button.
If the problem persists after trying these steps, we recommend contacting the technical support of your Service Provider who supplied the device, as they are best suited to provide the necessary assistance for your device.
