Using a Fios Gateway Router f(Model G3100) for my wireless network and a Macbook Pro. I get this error message multiple times each day. Restarting modem and restarting computer do not stop it from happening. I'm losing work because of this error. Can anyone suggest a fix?

On the MacBook Pro, go to System Preferences --> Network --> select your Network Adapter (Wi-Fi?). From here, click on the Advanced button.

If you're on macOS Ventura, then go to System Settings --> Network --> click Details next to your Wi-FI or Ethernet connection.

Once here, go to to the TCP/IP Tab and set IPv6 to "Link Local Only" and click OK. See if the problem continues. If it does, please return this back to the "Set Automatically" option. Let us know how this goes.
