I have a problem on my line and i need to rule out my house wiring but
i have one problem. The upload speed the my router connects at is
exactly half of what it should be and my download speed is not what it
should be either. I live very closed ot the exchange and a previous
line test showed that my line should be able to carry 17mbps. But i
get less than 2mbps downstream. The downstream cou8ld be a bad quality
line so that the higher frequencies are lost. But the upload should
not be affected becasue of the frequencies bieng below the downstream
on the line.

Downstream
Attenuation: 55db
Noise margin: 11db

Upstream
Attenuation:
Noise margin:

Does anyone know what could be the problem. I have tried plugging the
router in the socket behind the NTE5 master faceplate but the same
speeds. I have disconneted all the phones and other deivces so only
the router was on. Only difference was the the noise margin got better
to around 20db but the speeds were the same even though i changed the
SNR target manually to less than 6db.
