IP Profile Too Low?

A BT engineer recently visited home to resolve some problems I was having with slow broadband speeds (max speed was ~1.8Mbps). He fitted an NTE5 faceplate and since then, speeds have improved dramatically to around 3.4Mbps.

 

I have a very stable line, and had been synced at 4000kbps with an IP Profile of 3.5Mbps for over four days. However, after using the Kitz max speed calculator with my line attenuation of 51.1dB, I think I should be have an IP Profile of 4Mbps.

 

So, I restarted my HomeHub 2 to attempt to resync at a higher speed, but it has actually fallen to 3808kbps (I can't find out what my IP Profile is currently as I have already run one speedtest within the last 60min - as soon as I can find out, I'll share on here).

 

Attached are the results from my recent BT speedtest, and the ADSL line stats from immediately before my recent restart.

 

Am I being overly optimistic of my line being able to support an IP Profile of 4Mbps? Should I be able to squeeze out a bit more performance than I'm currently getting? I am connected to the HARBURY exchange and so still using ADSL Max.

 

Look forward to hearing your views.

 

Cheers, Matt

 

EDIT: Corrected reference of ADSL2 to ADSL Max.

Which type of master socket do you have?

Re: IP Profile Too Low

4meg on a 51db attenuation is a good connection rate. You won't get much more, and if you do, it might be slightly less stable.

Re: IP Profile Too Low

you are not on adsl2 but adslmax up to 8mb

 

in order to get a higher profile you need to get a faster connection speed and to get a 4mb profile you need a connection speed of at least 4544 which is possible on a good line with no noise problems

Re: IP Profile Too Low

I have one of the dual-socket ones (picture 3).

Re: IP Profile Too Low

imjolly,

 

Any suggestions for how to get a faster connection speed? Do I just need to restart my router periodically to see whether I can get it to sync at or over 4544?

 

Thanks, Matt

If you are plugged into the ADSL socket on the front, then you are not going to be able to improve anything at your end.

 

You will have to hope that the exchange is upgraded to ADSL2+ at some point.

 

Restarting the router too many times, will make matters worse.

Re: IP Profile Too Low


if only that would work but sadly that won't help and could make it worse.

 

there is little you can do with the socket as filtered faceplate is the best way to connect.  A shielded cable from router to socket to eliminate any interference and also check this post for other ideas

Re: IP Profile Too Low

Thanks Keith.

 

The exchange is due to be upgraded to ADSL2+ in May so hopefully I'll see a small improvement then.

 

Regards, Matt

Re: IP Profile Too Low

Thanks for that suggestion.

 

I'll see whether one of those shielded cables improves matters.
