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 are: 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.

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 shitty modem, as far as reporting is concerned anyway.
