Hi there, @user_ul7j41. Thanks for reaching out to us here on the Community Forum and sorry to hear about the WiFi trouble. Have you attempted to reset the power for the gateway modem to see if that may help? Usually a simple reset solves most issues. Let us know!

Have you had a chance to see if any of those tips apply ?
