6 - 10mb, estimated 6 only getting 4mb connection!

VPI/VCI 0/38
Type PPPoA
Modulation G.992.3 Annex A
Latency type Fast
Noise margin (Down/Up) 11.9 dB / 6.3 dB
Line attenuation (Down/Up) 40.4 dB / 23.0 dB
Output power (Down/Up) 6.2 dBm / 1.5 dBm

At the family home and decided to do a speed test and then a line checker and the estimated was atleast 6mb but they are only getting between 2.5 and 3mb, connection of 4mb. How are these stats can speed be improved?

Something quite badly wrong there, with something causing considerable instability. I would suspect at the premises rather than externally.

Am I right in thinking it is a Netgear router, or perhaps a Speedtouch/Technicolor? I'd be interested in the error stats if so and can give you the telnet instructions.

Re the stats you posted,you have missed out the vital connection speeds. As well as the high noise margin, which suggests problems, it is connecting using ADSL2 rather than the expected ADSL2+. Not only that, but with 40.4dB attenuation I would expect 8-9Mbps connection, not the estimated 6Mbps. (That discrepancy is common). I don't like the output power figures either. That may be an exchange issue.

The stats (including connection speeds) using the test socket, on the wall at the back in this pic would be useful, with the normal stats retaken immediately before.

Have a browse of this section of my website. Ignore the router acting oddly and add speed test results pages, they don't apply to this case, but I bet something in the rest does.

Thanks fella.

Have always felt there has been something wrong with it, in the past they had alot of downtime... disconnections and engineer visits, the router at first was plugged into one of the other sockets NOT the main socket as it was faulty.

This is the main socket

Noise margin (Down/Up) 11.9 dB / 5.9 dB
Line attenuation (Down/Up) 40.3 dB / 23.1 dB
Output power (Down/Up) 6.1 dBm / 1.6 dBm

Downstream 4,027 Kbps
Upstream 1,051 Kbps

Its a BT HOME HUB v2, Black one..

MASTER SOCKET - TEST SOCKET

Noise margin (Down/Up) 11.6 dB / 6.0 dB
Line attenuation (Down/Up) 44.7 dB / 23.2 dB
Output power (Down/Up) 8.0 dBm / 1.7 dBm

Downstream 5,247 Kbps
Upstream 1,119 Kbps

So it's the faceplate and the other sockets!

Certainly a factor. And judging by the attenuation using the test socket it is also showing Mode G.992.5, which is ADSL2+.

Go through that Troubleshooting section. The ring wire in particular can cost up to 2Mbps just by being connected at the master. Also Sky boxes (some people don't realise they have to be on a filter) and faulty filters are prime causes of trouble.

If I plug the router into the Test Socket, all the sockets in the entire house go dead which means that needs to be sorted some how. As i'd like to use the test socket for the time being till i get a new iplate.

So how would i get the other sockets working if i'm using the test socket?
Also all the other sockets have microfilters to sky boxes

Cheers for all the help

No need for an iplate

Look at http://www.thinkbroadband.com/faq/sections/radsl.htm...

If you want to have a different plate, dont bother with iPlate, but get an ADSL faceplate e.g. http://www.adslnation.com/phpapps/catalog/product_in...

Then no need for filters at the extensions, ie. neater

Tadda!!

Ring Wire, read your website all sockets work and using the standard faceplate from master socket

Downstream 5,368 Kbps
Upstream 1,048 Kbps

ADSL Settings
VPI/VCI 0/38
Type PPPoA
Modulation G.992.5 Annex A
Latency type Fast
Noise margin (Down/Up) 11.7 dB / 5.2 dB
Line attenuation (Down/Up) 44.8 dB / 22.9 dB
Output power (Down/Up) 8.1 dBm / 1.5 dBm

Result! (So far).

With luck they will now have stability. How old are the Sky boxes, and how many? Double filtering them can help.

The next step is the noise margin, which has been set to a connection time 12dB. Standard is 6dB. It should reduce automatically in two steps, taking 10-14 days per step, but it is possible, (perhaps with some difficulty), to get it reset within a couple of days. I expect they call it an SNR reset. That redoes the 10-day training period..

Did look for ISP name, but not spotted it, so this applies to BT Wholesale

SNR target training is a permanent fixture, not just part of the 10 day training period. A reset of the target noise margin does not cause a relearn of the MSR (a paper/record keeping exercise). It looks that way as some providers initiate a target noise margin reset via a complete reset of the line, rather than just a SNR target margin change.
