Problems with speed & dropouts

[steveb255]

Hi,

I have had a DG834GT now for about 4 years, most of which were in our old house and never once had a problem with the router and got great up and down speeds.

We've recently moved house and when I moved in, first thing I did was plug the router in to see if I could get any internet - great, I could - even though Sky (my ISP) hadn't actually connected my new broadband in the new house. I assumed I was using the previous occupants connection.

During the the time it took for Sky to get me connected at the exchange I had speeds between 10Mb and 15Mb and no dropping connections. Then Sky got me connected at the local exchange and ever since my speed is up & down regularly and get regular dropouts.

I have spoken to Sky engineers about it and they have suggested there could be line problems, they have run tests, put me on DLM etc but as soon as they see a reasonable speed on my router they close the call.

Here are some stats from the socket in my home office and into the main socket that I did at the weekend:

Test 1 - in office (filtered ADSL Nation XTF-68 faceplate):

Downstream: 10238kbps
Upstream: 415kbps
Line Attenuation Down: 29.5db
Line Attenuation Up: 18.1db
Noise Margin Down: 1.7db
Noise Margin Up: 16db

Test 2 - in main BT socket (filtered ADSL Nation XTE-2005 faceplate):

Downstream: 10237kbps
Upstream: 415kbps
Line Attenuation Down: 29.0db
Line Attenuation Up: 17.7db
Noise Margin Down: 7.3db
Noise Margin Up: 8.4db

Test 3 - in main BT TEST socket (tradional plug-in filter):

Downstream: 10236kbps
Upstream: 415kbps
Line Attenuation Down: 28.5db
Line Attenuation Up: 17.5db
Noise Margin Down: 4.6db
Noise Margin Up: 2.3db

The 10Mb download on those stats didnt last long, it droped to 3 or 4 and has been up and down like a yo-yo since.

Any suggestions of how I might get a stable connection?

Thanks a lot

Steve

Test 2 gives the best noise margin so you're looking at a noisey line somewhere...

[Isitme]

Agreed and the result in the Test socket must be wrong, it cannot be worse than the other connections. This could be due to a faulty filter or a poor connection between the filter and the socket.

[steveb255]

I'm assuming that a higher db for Noise Margin is better than a lower db? I'm not exactly sure what the stats tell me with regard to Noise Margin and Attenuation and what are a good set of stats.

I think the plug in filter on test 3 might be dodgy as with that plugged in the dropouts are even worse, hence the reason I switched to the ADSL Nation faceplates.

The office socket is at the end of the cabling which goes from the main socket to a socket in the lounge and then up to the office. All cables run around the outside of the house and in through the walls.

Thanks for the help.

Hi here`s some information that might come in handy http://www.skyuser.co.uk/forum/route...explained.html and http://www.skyuser.co.uk/forum/sky-b...eviations.html
has the face plate got two separate connections one for the telephone and the other for the router.

[steveb255]

Thanks for the links.

Yes, in the office its an ADSL Nation XTF faceplate which has both an ADSL and telephone socket built into the faceplate.

Cheers

Hi I am sure it says you do not need filters as the connections have a suppressor built in do you have filters fitted

[steveb255]

Sorry, should have explained better.

I only used a plug in filter on the test straight into the main BT test socket (test 3). All the other tests the router was plugged directly into the RJ11 socket on the ADSL Nation faceplate.

Cheers

Hi at the back of the Master socket faceplate has one of the main wires become loose. Just enough to move when you are using the test socket then when you refit the faceplate it tightens up again

[simonmpoulton]

If your using an XTE-2005 you should really get the same result from the test socket as you do with it
Steve has made an excellent suggestion regarding checking the main wires into the back of the master socket.
Your attenuation actually shows you should be getting more speed than your getting, I would've expected at least 14mb - hell I get 14mb with 34.0db attenuation!
