yeah i had the same issue then i did a power cycle and it came all good (downloading at 1.4 mb/s) but this morning it was bad again. (syncing at 8mb speeds) i still have adsl2+ upload speeds but 8mb download speeds where i could have 15mb :(

but my app is still pending. maybe exetel will figure something out.

Might be an 8Mbps stability profile. You can try emailing residentialsupport@exetel.com.au to see if this is the case and ask for it to be removed in order for you to test the speed and stability

Just changed fro ADSL1 to ADSL2 and I am also having the same problem. I just tried power cycling the router, same result.

No you're not. Your speeds seem perfectly fine

7.5Mbps throughput is a good speed and is pretty much average for ADSL2+. If anything, it is well above average for your attenuation, which is quite high (you are syncing slightly higher than your "attainable rate", which is a little strange, but oh well...)

Why does broadband choice website say TE-2D 24576/1024?. I only live 1.6kms from the exchange, 24Mbps to 8Mbps is a big difference.

24Mbps is a theoretical maximum for ADSL2+. To obtain it, you would have to live *inside* the exchange.

While you might live 1.6km away from the exchange, what matters is cable length, not line of sight or street distance. The actual phone cable can follow a much longer path to get to your house, and it might be below average quality, or contain lots of joins, etc. 45dB attenuation would be equivalent to about 3.2km of cable length. At this cable length, your speed potential is reduced to about 8Mbps. Even at 1.6km of distance, the average speed is about 11Mbps (obtained from http://www.exetel.com.au/pdf/downstream.pdf)

Well, that seems to make sense. I stand corrected. :)
