Upgrade then Down Grade back to Upgrade and then S...

Question

What are BT or BT Wholesale playing at the minute with my broadband? Yesterday I was on ADSL Max WBC.
Yesterday my Router settings said my Modulation was 992.1, my Line Attenuation was 50.0 dB and my IP Profile was 4000kbps. My Noise Margin would usually hang around between 5.8 - 6.7 dB.
Check earlier today and suddenly my Modulation was 992.5, my Line Attenuation was 53.3 dB and my IP Profile was 5782kbps. Noise Margin was 2.8 dB and hadn't seen it go any higher.
Now I just go and check again not 20 minutes ago and now my Modulation is 992.3, Line Attenuation is back to 50.0 dB and IP Profile reset to 5166kbps and the Noise Margin is still 2.8 dB.
No I know my line (cable length) is just over 2 miles, about 3.5km so know I will never see 10mbps+ but is it normal for BT to keeps Upgrading yout then suddenly Down Grading it later the same day?
Oh, the speedtester has not done my upload speed but yesterday it averaged about 0.36mbps and now it regularly comes out at 0.75mbps.

Answer 1

Hi
You are changing between adsl 2 and adsl2+ this can happen while the line finds stability during your 10 day line training period the exchange equipment will select which ever version is the most stable for your line
