Hi, and apologies in advance for complete tech-ignorance! Live in block of flats. Have FT-Orange landline + ADSL connection (via Netgear modem), which works well. Now need to convert TV to digital, so have ordered Décodeur TV UHD 86 + all the requisite cables etc. Will the décodeur operate if plugged into the Netgear modem, or must I acquire an Orange Livebox? Please advise. Cheers in advance, Min
