Default Router stats and broadband speeds

Comments appreciated on friend's not very good connection speed (TalkTalk
LLU - Huawei modem-router - Echolife HG520s)

Data path - Fast
Operation mode - ADSL2
Stats a Bandwidth down/up - 515/107
SNR Margin down/up - 7.9/23.6
Attenuation down/up - 48/38
Power down/up - 0.0/12.3
CRC down/up - 10229/0
FEC down/up - 5455/0
HEC down/up - 8738/0

Shouldn't the speeds be better than that?
Could the router be faulty?
Wouldn't interleaving help (can it be set from the router)?
What's the significant of 0.0 power down - looks odd!
Distance from exchange is probably a little over 3 miles.

Any thought/ideas/solutions appreciated on ways of improving the connection
speeds.

Many thanks in advance.

Given the stats quoted, the speed is as predicted here :-

If he has an NTE5 master socket he could try a filtered faceplate :-

and removing the bellwire :-

What you quoted makes little sense and lacks information for qualification.
I believe ADSL sync rates can only be adjusted in 4kb/s increments (don't
think ADSL2 is any different) so the 515/107 quoted isn't sync speeds.
Maybe it is the actual data rate in bytes/s averaged over some period.

That there is some non-zero figure called FEC indicates the connection is
interleaved.

The modem does not transmit in the downward direction so there is no power
to report.

Looks like a ****ty modem, as far as reporting is concerned anyway.

What's the significant of 0.0 power down - looks odd!
Distance from exchange is probably a little over 3 miles.


The 0.0 probably means that the modem can't get the far ends
sending power because of software incompatibility with the DSLAM.
Put the modem next to the incoming line socket or NTE5
with no phones or anything else connected for a test
what sync speed does it show?
There are modems that work well on long lines, the topic
has been well vented here.
Given the down figures for SNR Margin, CRC, attenuation
he is on a marginal line.
