I have a really weird problem, when someone rings our land line, once the phone call has finished and either party hangs up, the modem will drop its connection and then auto-reconnect. This gets annoying when downloading large files!

I've plugged the modem/router (Netgear DG834GT) directly in to the master test socket with nothing else attached at all and then phoned our number and hung up after a few rings and the router STILL resets!

I have also tried 3 different types of splitters in the master socket with just the router attached and same thing each time. I'm guessing it must be a fault on the BT side but don't want to get them out until I'm sure.

Has anyone else had this before or have any idea what the problem could be? I noticed in America when they see this problem they remove a test box device that's present in some installations which causes this to happen. Here in the UK, do we have outside phone cabinet things?
 
Which filters and how can I get access to them?? The splitters I'm using for the phone/router are filters, I just worded it wrongly if you meant those ones.
 
Those little boxes with two sockets for your phone and ADSL and a cable to the socket are called (micro)filters. You don't need those if you don't have a phone though - if you have a cable with a BT plug at one end and an RJ11 at the other (like for a 56k modem), you can use that. It would eliminate dodgy filters.

As for "test box devices", no idea what you're talking about.
 
I worded microfilters wrongly calling them splitters. I had the adsl router plugged in the master test socket with various splitters and it still does it.

I'm guessing it has to be a line fault as I've basically eliminated everything else other than a faulty router. I'll give BT a ring and no doubt have to go through all these steps again with a call center guy/girl.
 
One thing that maybe worth a try is to remove the front of the main BT socket and underneath you will see that this front plate plugs into another telephone socket.

Try plugging it in there and see how it goes, you'll still need a microfilter.

Same applies for the test socket.
 
I had this problem, along with intermittent noise on the line, I had a lot of phone calls and offsite tests and on the second bt callout they swapped my line over to a different cable back to the exchange and all was cured. filters would be the first thing to check in the test socket because if you get bt out and its your equipment, you will get charged

Ok, I will swap over the cable from the router to the phone socket, that's the only thing not tested now. I'll give them a ring tomorrow, who knows maybe it's a problem that might even fix our slow broadband speeds (1.5 mbit on a 8mbit line). I can dream!
 
make sure you unplug all internal phone extensions, plug the router into the master test socket and if possible get a wired phone to use with it to test the phone isn't at fault, I bought a new wired phone from tesco for a few pounds. Bt will get you to test this stuff anyway.

raise the fault with your isp as bt don't generally want to know about broadband faults, hopefully your isp has good customer support. I left my last one while trying to sort out my problem as I was on hold for ages.

as k3v says

remove all extentions for now

just plug 1x microfilter into the main line, and the router & a phone, and test.

You wouldn't usually phone a different ISP from the one you're paying to report a fault with your ADSL.

If the voice service has anything wrong with it, report that to BT but don't mention the ADSL.
