How to solve evening sync problems?

I seem to have a problem with loosing sync in the evening. This tends to manifest itself at the most inconvenient times - e.g. when playing games, resulting in being dropped from the server.

I was wondering if a change in router may help or if there is something IDNet could do. I don't really want to go to an interleaved profile though as that will increase the pings for my games.

I'm currently using a Linksys WAG200G. I was thinking of getting:


  • a Billion router as I've heard very good reports of those, also
  • a Netgear DG834G. I used to have one of these but got rid of it as I don't think the V1 played very well with ADSL 2+. I've also seen
  • a 2Wire 2700 mentioned here but have never heard of them and can't see them at my usual online retailers.

Interestingly, the sync speed seems to be around 3/4Mbit more than when the line used to be more stable. Is there a way of setting a
higher target for downstream margin or lower target sync speed with some routers?

It's fine in the day (around 5db average) but becomes unstable at night (around 2db average)

Here's a sample routerstats 24h plot:

The usual noise margin increase is causing the resync. BT 2 wires are available on eBay and are useful on long lines particularly. The draytek 2710 seems to doing  well also. Whether IDNet can get your margin set higher on adsl 2+ you'll have to ask them

Have you done all the usual things like making sure the ring wire is disconnected? That looks very much as though it could be interference from radio transmitters etc...

Yep, the last time a BT engineer called he fitted one of the new splitter plates that also isolate the ringwire.

Well, it still looks like radio interference to me, but as the ring wire theory isn't tenable I'm not sure what else you can do.

What sort of cable (and how long is it) from the master socket to your modem(/router)? If it's a long run of flat twin it might be worth replacing it with twisted pair.

Just the standard phone cable that came with the modem, it only needs to go about 4ft. Twisted pair is a good shout though, I'll give that a bash. I'll see if I can get something premade from Maplin or somewhere.

When I was having some problems I bought one of these:

Though I have to say that it didn't make any difference, interference wasn't the problem!

Ah great, thanks for the link. Worth 4 quid to eliminate that as a problem at least, before I spend a ton on another router.

Oh, I looked at my router stats & it's interleaved anyway :(

FWIW I've just bought another brand new 2700 for £8.50 off e-bay.  The PSU on my current 2700 is putting out a lot of RF noise and this seemed a good buy compared to the price of a new PSU.   :)

Even if the PSU with this one turns out to be noisy, £8.50 won't break the bank.  TBH given the price you can pick them up for it would be worth it to try one on your line.  Unless of course you need things like VPN termination.

Is your line overhead or underground? Also do you have your router cabling near electrical cables?
Damned, if you do damned if you don't

Thanks - good thinks to check. Underground & not particularly close. I'll try & routing it further away from any computer cables & see if that help though.

If you can try a different filter if possible, also a filtered faceplate is a good thing, failing that try via the master socket just to make sure its not your wiring once you have upgraded your cable, always use short runs and use shielded cables as has been said. :thumb:
