If your switch-over is anything like mine was - no-one enters your house. I am with Telstra (unfortunately). They sent me a new wifi modem, NBN ready. All i had to do was swap it over. When we were made "live" I had to put the cord from the phone, that used to go into the plug on the wall into the phone plug in the new modem. (if that makes any sense?

). My speeds tripled!
Also - spare a thought for the poor tradie, that has to go into random's home cos somehow he's classed as an essential service.
The small conspiracy theory part of me recons the NBN is being pushed again by the govt cos corporate still want their slaves working as fast as they can now they've been "forced" to let them work from home. Notice how foxtel gave all the channels for free? and those ads on the kids channels telling the kids to be good & relax & watch TV (so mum/dad can work). Made me feel ill.
I do often wonder tho, come next storm, when we have a 3 day blackout, you can't call anyone for help. Mobile would be flat by then. I wants my landline baaaaack!
