Patton, who has been a constant critic of the multi-technology mix that the Coalition Government has opted for, told the radio station 2GB on Tuesday that the NBN Co was trying to use aging copper wires which did not deliver the speeds that people wanted now or in the future.
He spoke to host Ben Fordham on a day when a report in The Australian claimed that NBN costs were behind the slow speeds that consumers are experiencing.
"Most of the work, the bulk of the work they've done has been in regional areas and they haven't tried to roll out into the more aging parts of the Telstra network," Patton said.
He said the key issue was the CVC pricing, "the wholesale pricing mechanism that NBN Co is using discourages their resellers, the RSPs, from actually passing on high speeds".
"So we've got two things coming together and colliding to create a nightmare – and people who are currently using ADSL2 are routinely telling us that they move to the NBN and find that their speeds are either the same or slower, and of course it's costing them the same amount of money."
Patton said there would be light at the end of the tunnel only when Prime Minister Malcolm Turnbull "acknowledges that he took advice from a group of people who were flawed in their thinking, and he's got an NBN management that's determined to try to justify what they're doing - and until someone says, hey, stop this, it's ridiculous, let's rethink this".
He said he had raised the issue with Turnbull and Opposition Leader Bill Shorten. "It's time Australia said, hang on a sec, do we want to be part of the 21st century digitally-enabled world or not? And if we do we need to do something about it."
