Slow ADSL2+ D Link DSL 504T v2

Post by basnarms » Sat Sep 04, 2010 12:47 pm

Hey eversince I ordered ADSL2+ I got dropouts (approx 2 weeks ago) then exetel/telstra fix my drop outs NOW its 4 sep & should have ADSL2 speed but its always on 7000/855 been like this speed since I ordered, My old ADSL1 8000/384 plan was always 8034/384 speed So my upload has increased but my download has decreased ?

Ok is the D link DSL 504T v2 compatable on the EXETEL network ?

Is the D Link DSL 504T v2 a TRUE ADSL2+ router/modem or just a ADSL1 router/modem ?

Disclaimer:
- D-Link Australia does not guarantee that this firmware
is fully compatible with all Internet Providers' ADSL2/2+ DSLAMs.
- Please confirm with your Internet Provider the availability
of ADSL2/2+ services in your area.
- Upgrading the modem/router to the ADSL2/2+ firmware is not
reversible without returning the product to D-Link Australia
RMA Dept. ADSL2/2+ firmware is however backward compatible
with ADSL(1).

So do I need to get another ADSL2+ Router/Modem ?


My Router info:

ADSL Status

ADSL status shows the ADSL physical layer status.

ADSL Firmware Version: 4.03.03.00 - 3.02.00.03 - 3.02.06.00 Annex A - 01.07.02 - 0.49
ADSL Software Version: V2.00B13.AU_20070425
Line State Connected
Modulation Multi-mode
Annex Mode ANNEX_A
Max Tx Power -38 dBm/Hz

Item Downstream Upstream Unit
SNR Margin 12 12 dB
Line Attenuation 42 28 dB
Data Rate 7002 797 kbps


Its funny how I have a good upload speed BUT download is crap It should atleast be 14000/797

btw: I using PPPOE to connect & in MultiMode

cheers

You will not obtain a speed of 14000 downstream with a line attenuation of 42.
Your data rate could be in the range of 7000 - 9000

The DSL-504T-GenII model was an ADSL2+ capable unit. Early 504Ts are ADSL1 only models. Your PPPoE connection is correct. As Outbush says, you cannot expect high downstream speeds from a line with that attenuation. Was attenuation significantly different when you were on ADSL1?

Yes I have the DSL-504T v2 NOT a GEN 2, My modem prob just goes into ADSL1 mode instead of ADSL2+, I know my attenuation is High BUT why was ADSL1 faster 8000/384 ? My upstream is Great :) on ADSL2

I reakon its my Modem/Router & I know I wont get 20000/1000 speeds But higher then 8000 would be good OR I should just change back to ADSL1 8000/384

I cant remember my line attenuation on ADSL1 Bugger :(

Anyone know of a GOOD ADSL2+ Modem/Router 4 port What runs on the EXETEL network ? I heard Alcatel good for ppl with High Line Attenuation thats why Telstra used them

maybe my DSL-504T v2 is causing the High Line Attenuation Well i googled it & got this link http://forums.whirlpool.net.au/archive/1464656 I think Iam only about 2.8 - 2.5 kms away from my exchange

Syncs fluctuate a little bit and ADSL1 and ADSL2 operate on different frequencies, which can result in even more fluctuation between sync speeds. While a drop from 8Mbps to 7Mbps is disappointing (and rather unusual), it is not overly surprising.

Possible, but I doubt it. As for others on this thread, I think it is mainly your line attenuation and that your expectations of speed are too high

With such high attenuation, higher than 8000 does not seem possible. Based on the attenuation, I think you are further than 2.8km as well, which is what I mean when I say "your expectation are too high". What matters is cable length, not line of sight, or road distance length. Many (all?) online distance estiamtors understate the true length of cable. Also, many other factors can increase the effective "length" of the cable such as lower than average cable quality, lots of splices or changes in the gauge of the wire, etc

This might be the best for you, but you should weigh up the monthly cost and the increases upstream (which can come in handy if you use VOIP, say). First though, I'd try borrowing a different modem from someone and testing to see if a new modem might solve your issue (you might find that a different modem can manage, perhaps, 9Mbps+ compared to the DLink's 7Mbps. This would also not be surprising as different modems perform differently under different line conditions and I've never been a fan of DLinks at all. I think they underperform the most out of all the modems

Why do that? It will probably cost you more and you will not have the good upload speed for Voip and file transfer.
Investigate different modems that possibly will give you better performance with your line length.

Hey well I got a netgear DG 834 v4 & it runs a little bit faster then the D Link approx 1000 - 1200kb BUT with the splitter its around 2500 less

It seems i am futher from the Exchange with the Netgear stats, Its like the D Link was incorrect

Line Attenuation 47.5 db 27.1 db
Noise Margin 12.2 db 13.3 db
but i still happy with the netgear the upload increased too

is there anyway to get the most out of my Netgear ? as in speed kb

cheers

I'm a little confused - "with the splitter its around 2500 less" - what does this mean in detail? (A modem must not be on a filtered connection)
The Netgear guide is at http://exewiki.exetel.com.au/index.php?title=DG834

Well when I use the Netgear splitter with PH connected I get approx 5400kb & without the splitter or PH connected I get about 7900kb lol

thanks for the link

I dont use the landline PH anyway (i got VOIP) So i connect straight to the PH line with no splitter

This means there is something wrong with your splitter. Some phones (particularly cordless varieties) need good quality filters / splitters to ensure none of the interference passes to the phone line.
