Problem with XF-1e's

Lance · Mar 29, 2007, 14:25:30

Well, the BT results came back all clear. What I'm going to do is see how the connection holds tonight and if it shows any problems get BT to do a retest.

Them damn inanimate objects, they have a life of their own!

p.s Andrew answered the phone in three rings rather than six - normal service is resumed!

Don't they just.

Thank goodness for that, I thought standards were slipping for a while there!

Tonight my line seems on the whole a lot better, although it is still dropping low occasionally.

Attached is the router stats graph, and log file, for tonight. It seems the noise margin has slowly dropped from around nine to six, but as it's done so at peak time I guess there is more noise on the lines and this is to be expected.

It seems there is still a slight fault but I wonder if the self healing process it appears to be going through will iron it out completely!

Well, I don't drop to -4db, Lance, but in other respects that graph could be mine. Certainly, I am getting noise pickup from somewhere, and having eliminated everything I can in the house, I feel it has to be mains-borne.

Your u/s sync speed is odd, though.

Normally, it would be the normal 448 but with the problems my line had it seems to have dropped off. I'll reboot the router later and see what sync I get then.

Looking again, the u/s noise margin is also low (which would explain the sync speed). My instincts say that it has to be a line issue of some sort, but it's the where which is the problem.

Lance · Mar 30, 2007, 08:38:20

My u/s noise margin is always a bit funny. Sometimes it will be around 6 or 7 with low sync but if I reboot the router it will shoot up to the 448 with a noise margin between 12-17.

As you say, I'm convinced there is a problem on the line somewhere, but I guess that until it gets worse and therefore detectable by BT, nothing can be done about it.

Noticed how we have stayed on topic for so many posts!

Worrying isn't it.

Time for an update:

Success! My line has now settled down and the problems I had with disconnects and my noise margin sinking like a stone have gone away all by themselves.

Best of all, from a combination of the new XF-1Es and a shielded cable between my router and filter, I am now syncing around 4640k, giving a profile of 4000. Previously, on a good day with back-wind, I was on a profile of 3500, failing that 3000. Therefore, I'm now going faster than I ever have before! Yippee!!!!!

Great news, Lance. I hope things stay good for you.

Lance · Apr 02, 2007, 09:52:42

So Do I! i just hope the problem I believe is to do with my line doesn't appear again.

Rik · Apr 02, 2007, 09:56:11

That's a feeling I can empathise with.
