I'm using Vodafone Ultra Hub (H500-T) as modem for Fibre broadband and Landline services, but Vodafone only provides basic information on how to use this modem. There should be a thick detailed operation manual for this device to better utilize the features/functionalities of this modem. Does anyone know how to get a copy of this information for this modem? By the way, this modem is made in Vietnam.
