lots of resync-ing

krysia · Dec 15, 2009, 16:48:49

Hello all! My connection has been funny this afternoon - my PPP session hasn't dropped, but ADSL has re-synced three times while I've been at the computer (perhaps even more when I've been away). The second time I went into my router and checked the SNR - refreshing the page a few times showed me it was bouncing up and down. Usually both that and my connection are rock-solid. I'm on the Brixton exchange - anyone else experiencing this?

Hi Krysia

I've not seen any other reports, so it would be worth giving support a ring to see if there's a BT issue affecting you (there's quite a few at thee moment).

krysia · Dec 15, 2009, 17:28:22

Thanks, Rik. I think it may be my router - Support says my connection hasn't dropped at all (and my router shows my PPP connection has been up for 7 days), despite my ADSL light flashing and my momentary losses of connection. Strange!

Very. Can you run Routerstats? (That is, which router do you have?)

Hi Rik. I've got a Billion 7402VGP VOIP router, which can give me lots of information:

Model Name    BiPAC 7402VGP

Routerstats Lite doesn't support that particular model, but does four others, so might be worth a try:

QuoteElapsed Time 0 day 1 hr 51 min 42 sec

PPP Connection Connection established
Connected time so far 7 days, 5 hours

Those two times seem contradictory.

You can say that again - they're impossible!

Rik · Dec 15, 2009, 19:06:03

That's the puzzle. If support haven't seen any drops, it suggests a fault with the router. Do you have a spare you could try?

krysia · Dec 15, 2009, 19:27:20

It seems to have settled down (fingers crossed), so I'll keep an eye on it - too much to do before Christmas to unplug everything and try my old and inadequate BT Voyager! Thanks a lot for your help.

Good luck.

Baz - that looks like a noisy line resync to me - the multiple entries in a short space of time suggest the router trying to find something it can work with.

If it's been stable since - I'd ignore it. Otherwise, call support.

Given the timing, Steve, the other possibility is BT work at the exchange.
