Quick line check please

[old Bill]

As I know everyone here is so good and friendly  would someone please cast a eye over my line stats. I am very happy with the speed but not to sure if I am pushing my line to much. Sky have capped my line at 8.5 meg but say it should only be about 5. Any views please.

All looks good, bill, as long as your noise margin doesn't drop too much during the night.

[Sebby]

I'd say you're at the max (no pun intended), Bill, given that your noise margin is ~6dB at night, but things look absolutely fine.

Just to give you an idea, my sync is just over half of yours, and our attenuation is identical, although my target SNRM is 9dB (for stability) and I'm not on ADSL2+.

[old Bill]

When I was on ADSL (up to 8 meg) my nm never moved from the default of 7. Now that I am on ADSL2+ it seems to drop quite quickly in the evening. Sky put me on the uncapped Sky Max package. My sync went up to 9.8 meg but my connection was just unuseable.

[old Bill]

Just spoke to soon. NM was holding at 5.5 then it just lost sync. No warning no big drop in NM. Very strange.

[Sebby]

It could be the router. Some are more sensitive than others. As ADSL2+ is a different technology, I'd recommend you try posting on skyuser.co.uk as they're a lot more clued up.

[old Bill]

Hi many thanks for everyones help. Tried posting over on the Sky user forum, but it seems that no one was keen to help me. Have just dug out my old Speedtouch 585. The nm is a bit higher but it seems to create a LOT more FEC errors then the 2700. I am sure I read some ware that the 585 was very generous with the amount of errors on the line.

It is, Bill. Use the 2700 and don't worry.

Probably because they all know that Sky insist on their customers using the router pre-programmed and supplied by them.

[old Bill]

If Skys router was any good I would be happy to use it. It makes a good door stop. The only reason I was trying the 585 was to see if it would hold the line better in the evening.

[Steve]

No experience, may be complete nonsense but what about using the 585v6 and DMT modem tools to tweak the margin apparently its compatible with firmware 6.1 I think

[Sebby]

Don't worry about FECs, Bill, they are corrected errors. I would leave things as they are, with whichever router you prefer.

[old Bill]

A quick update. I have 2 2700 routers one using the SBC software and one using the BT software. I had for sometime just been using the SBC version as I liked the higher wireless power. Anyway I decided to try the BT version and it seems to hold on to the line and nm so much better. No loss of sync and a nice steady connection.

Thanks for everyones advice.

[Sebby]

Excellent.

I wouldn't say my dual SSID BT model is better in terms of sync or holding the line, but it doesn't suffer the 12 day reboot like the SBC firmware, which is a big plus for me.
