Dennis, if Optus are overloading their bandwidth as said before it is definitely a case for the ombudsman.
There is definitely a major problem if you are getting those two earlier poor download speeds as opposed to the really good one. If your linespeed is extremely good as indicated, the worst you could expect during peak periods is about half the download speed, which would be acceptable at about 9000kb/s with ADSL2+.
Cheers Rick.
