Troubleshooting and diagnostics
Even with proper setup, situations may arise where devices cannot see each other or the connection constantly drops. Most often, the problem lies in the router settings. AP Isolation (Access Point Isolation) prevents devices connected to Wi-Fi from exchanging data with each other. This feature must be disabled in the router settings.
