So on one line I get 2208Kbps download and on the other I get something around 7500Kbps download (both sync speeds).
These lines are very nearly right beside each other, they are within 10 metres of each other.
One is on BT (the 7500Kbps line) and the other is with Sky (both line rental + broadband).
I called up Sky today and told them this and they said that it must be a problem with my router. I told them that I've tried different routers and they continue to blame it on the microfilters etc.
They asked me if I plugged the modem directly into the test socket and I had did this, not a difference.
Does this mean that it is a problem externally? On the other line which is now achieving 7Mbps sync, I was previously getting speeds like this. It took six engineers and finally I complained to BT's CEO and he sent out probably one of their best engineers. He replaced the cables on the pole outside and told me that I had got the last pair or something and that if there was any other problems they'd need to get an underground team out.
So here's my router stats:
ADSL Link Downstream Upstream
Connection Speed 2208 kbps 448 kbps
Line Attenuation 37.0 db 19.5 db
Noise Margin 6.1 db 10.0 db
Poll Interval: (secs)
They are basically identical on the other line (with the best speeds except the downstream speed is different obviously).
1) If it does prove to be a fault on the pole, what happens next? Will they just say that they can't do anything because there's no more space left for anymore lines on the pole?
2) Does it mean if I plug into the test socket that it's a problem externally? There's no noise on the line.
3) How can I ensure I won't be charged if Sky give in and send an engineer out?
By the way, both lines are connected to the same cabinet. Get around the same attenuation and I have confirmed this with BTW.
