Located on Banks Peninsula previously (until 10 or so days ago) had connection with approximately "Maximum downstream rate of around 7000 (kbit/s) with Line standard ADSL2+".
Since then "Maximum downstream rate" is at its best 4700(kbit/s) dropping to under 2000(kbit/s) at times and line standard is now "ADSL_G.dmt.bis". Upstream rate has not changed and is still between 800 to 1000 (kbit/s). I appreciate that the connection speed will vary but would have thought that a reduction of 35% plus is not normal.
Have contacted vodafone about the issue they did a modem software update and port reset (I think thats what they said) but there has been no improvement.
Yesterday tried a different modem but again no improvement.
The connection had been getting better over the years something I only thought would continue.
Also in the past when checking Broadband availability maps I am 99% sure that the results use to say the best connection available at the address was ADSL2+. Looked yesterday and this is no longer the case, results said "Wireless is Available (0.25-5 Mbps down 0.25-0.25 Mbps up) and that ADSL is Not Available"
