Hi there docsou,
It sounds as though you're looking to connect to WiFi on a Apple Watch. Utilizing Wi-Fi on Apple Watch is a great feature, I'd be happy to assist in seeking a solution!
Below is a resource that can help:
"Your Apple Watch won't connect to 5GHz Wi-Fi or public networks that require logins, subscriptions, or profiles. These networks, called captive networks, can include free and pay networks in places like businesses, schools, dorms, apartments, hotels, and stores."
Connect your Apple Watch to Wi-Fi
Have a great day!
