Interweb woes

Briggykins · 15-09-2009, 11:23

Hi all,

I've just had ADSL set up at the new house, but unfortunately it isn't working very well. It takes a long time to sync (up to 10 minutes), and when it does it only syncs at 160kbs (when it's meant to be around 6mb). I've tried the test socket with no other devices attached to no avail, also with a replacement microfilter. I'm going to borrow an ADSL modem to try when I get home to eliminate the router as a problem.
My ISP (Vispa) have logged a fault with BT who state there isn't a problem at their end. They've offered to put in an engineer call in but obv I'll get charged for this if it's my problem and not theirs. Can anyone suggest anything else to try before I resort to this?

Cheers,

Brigs

Can you get any stats from your router? Attenuation and SNR would be very useful.

Is the voice service on the line OK?

Not noticed any problems with voice service. SNR according to Vispa was way down at 3 - I'll see what I can get off the router when I get home.

An SNR of 3 is a bit on the low side, I'd be expecting it to be about 5. What you ideally want is low attenuation and a high SNR (so lots of signal, little noise). Systems in the exchagne will alter your sync rate to find the fastest rate you can sync at that's stable and an SNR of about 5 is usually the target.

I had a problem where I kept losing sync and then connecting at around 160kbs. In the end it was the wiring from the pole to the house. BT came out and replaced it FOC. Just something to think about

Actually, not quite sure it's the same problem. Does your phone work OK?

Here's my old thread... http://www.boat-drinks.co.uk/showthread.php?t=7631

I had the same problem as Desmo. My phone wire was pulled tight around the corner of a brick and over time it got cut. BT replaced it.

Plug just a phone into the line, pick it up and check that the dial tone sounds normal. Now dial 0 (or any other digit) to get rid of the dial tone and listen to the line. If it's clear then the phone line is probably OK. Any crackling at all and you have a problem with the line.

It would be convenient if there were problems with the voice portion since in my experience getting them fixed often sorts ADSL problems.

Or use the BT line test facilities. Dial 17070 then 2 for a quietline test.

Good idea. Didn't even know that existed.

Beware the automated BT line tests though - they can get it wrong (on my line it used to report a fault where none existed). BT might have fixed that though as I haven't used it for ages.
