We had NBN installed about a year ago. We have a two storey house. The connection has been working well on the television that we use in the main lounge on the second storey.
We recently redecorated the first floor to use as a rumpus and second games tv area. We purchased a new smart tv for the room for that purpose. When setting this up we found that the tv aerial points that had previously been working prior to the nbn installation were now inactive and disconnected. We did not do this.
On calling out an antennae technician to check what the problem was, he explained, after checking all the antennae points on the first floor (all second floor ones are working) that the Optus nbn technician when installing the NBN, disconnected tv aerial points for three other tv points the first floor (that we used very infrequently) but now wish to use again. Our antenna tradesman said the NBN has been dodgily piggybacked onto our tv antenna as a shortcut to avoid further and proper work. We are now less the previous functionality of accessing signals from our downstairs aerial points. Obviously we would like this to be rectified by Optus who are responsible for the work (or lack thereof) of the contractor who botched our installation clearly to save himself time and money which we will incur remedying his negligent work.
