Connection Issue - Interference?

Rik · Dec 09, 2010, 10:19:32

My first thought would be a noisy line or environment, Swerv. As Steve says, support will need some BT tests done. Can you borrow an alternative router to try?

Steve · Dec 09, 2010, 10:29:09

Rik, Why on the last occasion do you think that the upstream has been hit so hard with the downstream spared?

Rik · Dec 09, 2010, 10:30:32

It's inexplicable, Steve, unless the noise just happened to fall in that frequency range. Swapping routers at this point would be useful to eliminate that as a cause.

I'm going to hook up the 2700 tonight guys. Just interested to see what the stats will be when I get home first though.

Here's the NM from overnight.

That is ugly.

Spoke to tech support again yesterday. They'd spotted that generally things had calmed down a little, in terms of re-sync's, although there were still the odd ones the modem was doing.

Speeds have stabilised as well. So they've reset the 10-day training period and hope that will stabilise the NM at nearer 10db. Just going to leave it a few days now. The NM looked a hell of a lot less ugly over the course of last night as well.

The only thing that worries me is that, on arrival home the last two evenings, my laptop hasn't been able to connect to the internet. I'm connected to the router, and the router appears to be connected to the 'net. I could only sort it last night with a reboot of the router, which I'm obviously keen to avoid.

Any pointers?

Try a cable connection. If that works, we need to examine your wireless setup.

Swerv · Dec 11, 2010, 20:07:36

Hi all. Tried cable connection this morning and no connection. This despite the routerstats suggesting it is connected

Is this a stale connection? Re-boot fixed it but obviously don't want to keep doing that.

It sounds like it, but it could be a router issue.

Swerv · Dec 31, 2010, 13:48:52

Bit of an update for you guys. A week before Christmas I spoke with tech support again and they said they could see the connection had been more stable, so they reset something (not sure what, as it wasn't the 10-day training). What was interesting was they said the distance from teh exchange and general line characteristics meant that it was pointless us being on ADSL2+ as the line was only capable of achieving 3.5M on the ADSL connection.

They suspected that because the router was syncing at 4.5M it was causing a build up of errors which were forcing the router to drop the connection and re-sync at the low speeds.

Anyhoo, bearing that in mind, we've since had a stable connection at 5.7Mbps! With NM of c6db. The noise is still a little "changeable". Definitely worse in the evening.

Altogether though things are much happier though

I must thank you all for you help over the last month.

Our pleasure, Swerv. I wonder if BT have been working at your exchange?

Swerv · Jan 04, 2011, 00:20:10

Well here's something interesting to ponder Rik. Only a couple of days after the trouble first started, the other half got a call from BT asking whether we were happy with our current provider and service, and whether we'd be interested in moving across to BT. They banged on about customer service and problem resolution etc.

As the trouble had just started the other half didn't say no but suggested they call back in a couple of weeks. Their call back about whether we wished to switch occurred the day before the connection finally stabilised...

Maybe I'm just too cynical.

Rik · Jan 04, 2011, 09:46:06

Or realistic.
