BT Broadband speed issues/questions

Go to solution

So I have posted here before due to low broadband speeds but it has seemed to sort itself out. Actually the noise dropped from 6 to 3? Is this any good because we are getting a couple more Mbps. Also I'd like to question the DSL Checker and the 'High and 'Low', according to that our line is caple of 50mbps but 40 is actually only coming down according to the router. I don't understand because about a month ago it was only 32 coming down the line? Is this a fault or is this normal? Thanks!image.pngimage.png

Oh, also we've found that the test socket with an ADSL filter is more stable than the filtered faceplate though there are no extensions plugged into it.

According to the checker, your line is capable of somewhere between 50.7 and 32.5. You are getting 40 so well within the range quoted. DLM has lowered your SNRM to improve your speed.

The high and low is an estimate of the speed range for your line. You are within that so all is good. Your noise margin at 3dB is normal with G.INP activated so again all is good.

More info on G.INP HERE

40 is the DSL sync speed, which is the speed all ISPs quote, the download (throughput) speed will always be less due to protocol overheads.

Ah, thanks. Any idea why using the test socket with an  ADSL Filter makes the line more stable and decreases the Line attenuation than if we used the filtered faceplate even though there are no extensions wired into it?

The filtered faceplate could be faulty, no problem with using test socket and filter if you are happy with it.
