ADSL2+ low sync speed

[happychappy]

seem to be getting really awful speeds...

Modem : D-Link 504T Genll
Modulation ADSL_2plus
Annex Mode Annex A 
Max Tx Power -38 dBm/Hz

SNR Margin [down 14] [up 15] dB
Line Attenuation [down 56]  [up 35] dB
Data Rate [down 3043] [up 569] kbps


Exchange: S.A/Adelaide/SALISBURY DA235 (Covers 79,282.5 square meters)
Line of Sight: 3838m

still using a old old adsl micro filter.
have unplugged the phones

is it just the crappy exchange?

Line of Sight: 3838m

Your actual cable length is likely to be in the order of 4700 Meters. If so a sync speed of 3043/569 is exceptional.

Line Attenuation [down 56]  [up 35] dB

Your sync speed is very good for the reported attenuation.

is it just the crappy exchange?

No, It is your line length that is slowing you down.

What you can try
- First: Set your modem to ADSL1 only. Your not going to get over 8Mbit so your not going to lose out on any speed. As the ADSL2+ frequencies attenuate more easily than ADSL, you might see a lower attenuation value and possibly a higher speed.
- Second: It appears you are on a "stability" profile (Your noise margins are around 14dB), you may have had dropouts in the past. You can call Tech Support to be taken off the stability profile. This might increase the risk of dropouts, but may also give you a higher speed. If you call, ask "Can I be taken off the stability profile?", the Tech's will know what to do.

[happychappy]

yeah i am on the stability profile because lately i have been having drop outs from 3 - 7pm.


ive tried different modes :

adsl2+(multi mode) connects
adsl2(multi mode) doesnt connect
adsl(multi mode) doesnt connect

there are other options

adsl2+ (annex m)
adsl2 (annex m)
adsl2+ (multi mode except annex m)
adsl (ansi t1.413)
adsl (itu g.992.2)
adsl (itu g.992.1)
RE-ADSL with DELT
RE-ADSL
adsl2 (itu g.992.3)with DELT
adsl2 (itu g.992.3)
adsl2+(multi-mode except t1.413)
adsl2+(itu g.992.5)with DELT
adsl2+(itu g.992.5)

adsl2+(multi mode) connects
adsl2(multi mode) doesnt connect
adsl(multi mode) doesnt connect

Looks like Multimode has been disabled on our side. You could call and ask for Multimode to be enabled.

Once enabled, you can then try the varions modulations.

adsl (itu g.992.1)

That's the one to try.

[happychappy]

k rang them up.

they said there is a problem some where not sure if he said the exchange or what not couldnt really understand him. Also he said dropping the profile wont matter ither.

[Angus]

Sounds like they want to play it safe with your connection. That's fair enough as dropouts are quite the nuisance.

If you want PM me your username and I will see if I can get somone to have a closer look.

[happychappy]

also im not sure if i am setup right



Red Lines = phone lines

it looks like someone has leeched off the first wall socket ? not sure if my setup will affect my internet

Also if both computers are on and browsing it for some reason will crash n just say waiting for a response , and this is not a LAN network issue because i have ruled that out.

[Angus]

Well the thing to try is plugging the modem into the other wall socket.

[happychappy]

just, tried line speed went up a bit , but still the modem drops out of sync and back in regularly.

spose next is a new modem? was i ment to get a free modem switching over to adsl2+ ? i switched from 512 Primus One plan , to Platinum 21 ADSL2+*

[happychappy]

i am not very happy at all .......... i had a steady connection 512k/256k.

now i still download at the same rates even thow my line connection has gone up to 3000k and i get about 50 line dropouts a day ? wtf? i thought iprimus was good 0_o

[Angus]

Looks like a phoneline problem.

The best advise is call Technical Support and advise them you are having dropouts. They will walk you through an isolation test and escalate the problem to our second level team to get fixed up.
