Sounds like a bargain for £4/mth.

[Vir Campestris]

Hope, rather than expect :) after all the line is out. Can it really not tell open circuit from a phone?

And that's roughly the setup that's got us 4.5 at 3 miles. I'm pleasantly surprised.

Open Reach were on the job, 9.00am. Confessional call to admit a wire was fitted to the wrong terminal.

Download still 1.0Meg but up jumped to 0.5!

I'll ask Demon to organise a reset next week and see where it stabilises before fiddling with our phone wiring.

Current sync here speed is 7424 kbps with a BRAS of 6780 kbps that's on about 2.5 miles of cable some of which is ali. That is actualy the best I have ever seen it and there is a 5 dB noise margin so it's not right on the raggedy edge of failing.

If the cable path really is only a mile and half that is crap. On ordinary ADSL2 or 2+ the upload has a maximum of 448 kbps. I guess something rounded that to 0.5 Mbps...

The line should automaticaly rate adapt no need to initiate the 10 day "training" period. Things can get confused if you have a lot of line noise for a period of time though. You do need to be able to see what your speed has been agreed between your modem and the DSLAM in the exchnage, it's proably visible somewhere in the modems configuration web pages.

With 4 micro filters in use I think you would see a great improvement by sorting out the extension wiring and having only one filter at the master socket to feed all the phone sockets. And have a seperate dedicated unfiltered feed to the modem.

between 8am

I got it then had a fault within a week. Fixed within 24hrs, well pleased.

was....

That is one slight snag you can't log the fault online, the site refuses to accept it. So you can't avoid Bangalore. B-(

If the phone line is a single point of failure for both voice and internet and you have no workable backup (voice mobile and/or 3G, like us, weak signals) then it's well worth it. I'm not that fussed about not getting it fixed during the night but if that is important to you business lines can have Critical Care, fixed within 6 hours

Things are improving. Speed test at 09.30am got me 4.9Mb down 0.411 up and ping 217ms. I believe this service has been ADSL2+ since dec. 3rd.

Er.. interrogating routers is way outside my skill set and perhaps best discussed in a separate thread.

3 filters fitted. The 4 th. extension is not currently in use.

The feeds are all currently filtered at the hand set end as advised by my ISP. It might be possible to adapt the routing as you suggest but will one of the supplied filters be suitable?

Geographically, the router feed is the shortest.

Note that the bell wire issue is separate from the micro-filter issue. The bell wire(s), if left connected, act as aerials to pick up noise and reduce the number of channels available for the ADSL kit to use to pass data.

Having said that, I'd agree that the ideal setup is prolly one micro-filter at the master socket, and off that run phone wiring to the phones and cat5 to your router (wherever that is located).

OK The run to the router is about 7m in ordinary telephone twisted pairs.

I'll still need to let the existing arrangement stabilise so I can appreciate any further improvement.

While you chaps have got time on your hands... please see my request for a *dummies guide to understanding routers*:-)

That will be fine, assuming that it is reasonable quality telephone cable. You want solid copper conductors not CCS (Copper Clad Steel) or CCA (Copper Clad Aluminium).

From your other post it looks like it has sorted itself out overnight. BT changed the algorithm they use to determine how quickly things change quite a while ago. If there is a big difference between the BRAS rate and the sync rate it should change quicker than if the difference is small.

Done.

[Dave Liquorice]

Speedtest sites can be a bit unreliable as you don't know what bottle necks may come and go between you and it. If your ISP has one that's probably the best and most consistent to use as hopefully it is close to you in internet terms.

I'd expect a little more speed than 4.9 Mbps but strange/poor quality wiring and multiple micro-filters can easyily knock a Mbps or more off.

Simple for the great unwashed to do and understand but generally not accepted to be the way to get the best connection.

Possibly, might need a bit of "temporary bodging" on the telephone side.

If you have a standard split faceplate "master socket" the fed to the modem can be taken from the connectors on the back of the detachable lower half of the face plate. Assuming the filters have a flying lead plug that into the face plate socket then bodge a BT plug to open wires to feed the extension wiring. To get the terminated BT Plug maybe cut one, with a few inches of cable, off something you don't use/need.

The sheds sell BT plugs and a little crimping plate but really they need to go onto the flat cable that phones use than the round instalation cable.

Are all the filters you have the same make/model. Not all filters are created equal, some work better than others as far as reliable sync speed is concerned. It might be worth experimentation before finally tidying things up. You can also get filtered face plates I have one but don't use it as the BT branded MF50 inline filter gives better overall (night/day) ADSL performance.

Also note that the actual filter circuitry is in the feed to the phones, the ADSL side is connected directly to the incoming line.

I use broadbandspeedchecker.co.uk

The last two tests were from London with a ping of 109ms. (current

4.97Mb down and 0.487 up)

This may have peaked as you hint below.

For several years my connection ran at 5 to 6.0Mb. Recent line faults had dropped this to 1 to 2.0Mb. I am not certain that my router (Speedtouch ST585 v6) is able to handle ADSL2+ which may be apparent if I can get at the data.

I don't have a split face master but do have a twin splitter. Plenty of old cables to cannibalise:-)

Mine are all the same but Chinese Export Z-350UK

The user manual copy I found on the web says it does. With 1.5 miles (2,500 m) of pair from the exchange on ADSL2 you ought to be getting close to the maximum 8 Mbps. With ADSL2+ around 12 Mbps. That's with a good line and all the tips for improving any internal wiring done.

Go for it...

[tony sayer]

Hey ho!, glad we've got cable here, just one bit of co-ax and one modem and no other malarkey anywhere, consistent speed and to be uprated soon too from 30 to 50 M/bits!...

Yes but you have to live in Cambridge and put up with all the visiting Grockles:-)

[docholliday93]

In days of yore everything except the bell (in series with a capacitor so effectively open circuit as far as DC was concerned) was disconnected when the phone was on-hook.
