Broadband

Donna Noble, desiring to go shopping, once asked the Tenth Doctor if the TARDIS had broadband. (COMIC: The Greatest Mall in the Universe)

Later on, the TARDIS did indeed have broadband. The Twelfth Doctor told this to Bill Potts, telling her to watch some movies or something to pass the time while he was gone to blow up the colony planet. (TV: Smile)

The broadband in Stegmoor was very poor according to Matilda Gregson and Lilly. (AUDIO: Beachhead)
