Potential Speeds


[link to this post]
 
I'd like to have some feedback on my Router Stats. Our exchange has recently been upgraded to ADSL2+, and contrary to what I've read, my attenuation went down from 37db to 32.5db. My SNR ranges from 9 during the day to 1.5 late evenings. Should I be getting faster speeds than 6652? I'm using a Billion 7800N, but can't use the SNR tweak at the moment due to the drop in the evening.

DSP Firmware Version A2pB025f.d22k
DMT Status No Defect
Operational Mode ADSL2+
Upstream 444
Downstream 6652
SNR Margin(Upstream) 25.3
SNR Margin(Downstream) 5.1
Line Attenuation(Upstream) 16.4
Line Attenuation(Downstream) 32.5

Yesterday I saw nearly 8000 sync on a line with attenuation around 38 but the upstream was over 1000 - which ISP is this ? It was Tiscali / TalkTalk LLU I was looking at.

Have you checked the results in the test socket behind the master faceplate ?

My username is pretty old now been with two other ISPs since then. I am currently with ICUK.

We are around 1.5km from the exchange, but no more than 2km.

I used to get around a 6500 sync on ADSL Max before.

We don't have a that type of BT test socket. I think we have a simple master socket running two extensions, all with filters. But I plan to connect the router to the master socket this evening to see what happens.

I should get that sorted then. Maybe disconnect the extension wiring and see how that affects the speed at the master.

www.farina1.com/adsl says Your ADSL2+ speeds are likely to be in the range 11500Kbps to 15000Kbps

So you are under performing, put it this way, on my 46dB line with ADSL2+ I can sync at 8040Kbps

In reply to a post by regrettiscali:
contrary to what I've read, my attenuation went down from 37db to 32.5db.
Is that with the same router? Sometimes diff routers measure diff attns.

Your line should be syncing about 14 Meg, but I don't like the wide variation in NM over the day. Would not expect much more than 3 dB reduction overnight.

Indicates a wiring issue. Are you plugged into master socket and isolated any extensions?

Decided to install a BTO NTE5 and ADSLNation Filter/Plate.

Att is down to 31.5 and SNR has been a steady 8 give/take 0.3 each way all evening. Shall monitor for a while. I suspect my IP profilevis stuck on 6.5 for a while.
