Thread: Change from ADSL to ADSL 2+

EG ADSL at best is 1.5Mega Bites Per Second where ADSL2+ is 24Mega Bites Per Second (at the telephone exchange). However it slows down substantially the further you are away from the exchange - eg slows to about 8Mbps at 4 km from the exchange.

Any restrictions on when you can download is determined by the ISP not ADSL2+ technology.

ADSL is actually 8mb download and 512k (maybe 1mb) upload but telsta artificially capped the adsl to 1.5 / 256?k so they could screw more bandwidth through their lines (ie more customers less investment)

adsl2 is 12mb with 1.3 - 1.8mb upload

adsl2+ is 24mb down with 1mb / 3.5mb upload

the thing to note is adsl2+ relys on good lines, good filters, and speed drops off dramatically the further you are from the exchange. 24mb will ONLY be available if you live in the exchange. i live 1.5ks away and i get 14.5mb connection.

as an example when i was first connected i had an 8mb connection, upgraded all the lines to cat5e cable and had a central filter installed and the connection had jumped to 14.5mb.. well worth a small investment! if you live far enough away from the exchange sometimes its not worth upgrading the modem as you will never get beyond the 8mb, it never hurts tho

thanks

Saw an interesting graph on 'nodes site this AM where ADSL2+ had a better reach than ADSL.
ie. if you are a touch too far from the exchange now, ADSL2+ may reach.

I'll see if I can find it......

On the graph, the blue and green shaded areas show the theoretical maximum speeds you can obtain, at various distances from your local exchange, from Internode using ADSL, ADSL2 and ADSL2+ equipment.

there are some odd exceptions, i am at 7 klms and get 1.5mb on adsl, one of my clients is less than 300m from an exchange and cant hold 512k

there is more to it than just length of wire.
