Title: lots of resync-ing
Post by: krysia on 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).

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?)

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!

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?

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.

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.
