Speed problems, strange decline in service

[BGN]

Just wondering if anyone can offer up any help. Been with IDnet for about a month and tonight noticed a dip in connection speed. I've tried the following things, as per usual:

1) Rebooting the router. (Is a DG834Gv2 if at all helpful)
2) Powering the router off and then on once again.
3) Checked to see if the problem persists via wireless as well as wired connectivity.

I did a BT speed test and this is the result:

    IP profile for your line is - 135 kbps
    DSL connection rate: 672 kbps(UP-STREAM)  1184 kbps(DOWN-STREAM)
    Actual IP throughput achieved during the test was - 103 kbps

--------

Any more tests, advice and help appreciated, just thought to try here before calling support on this.

EDIT: Pardon me, where are my manners? Thanks in advance, of course.

IP profile for your line is - 135 kbps
    DSL connection rate: 672 kbps(UP-STREAM)  1184 kbps(DOWN-STREAM)
    Actual IP throughput achieved during the test was - 103 kbps

Your throughput is roughly correct for a IP profile of 135kbps. Looks like your going to have to wait about 3-5 days for your IP profile to raise back to 1000kbps.

Whats your Attenuation? and SNR

Hi there,

Those are the details I got from my router, I haven't a clue about this stuff, I'll be honest. I don't really know if that's within reasonable bounds or not. Thanks for such a quick reply.

EDIT, if I had to guess, is that unusually high? o_O

Well I'm no expert on the subject but i know a few things and just my own experience's have taut me a few things. Your line is very long by the looks of it 63db indicates that it's several km long. Your Noise margin is also high but this will be to stabilise your line. So i would think your connection speed of 1184 is about right.

All you can really do i think is wait a few days for your IP profile to raise back up to 1000kbps and your speeds should be back to normal.

Okay, thank you very much, I'll sit tight for a few days and hope for the best.

As far as it goes for the length of the line? I am quite a while away from the local exchange, and have had to extend the cable leading from the master socket in the home two bedrooms across, has always been like this so it might be worth trying the master socket sometime tomorrow, I guess. Either way, I'm sure it'll actually get sorted before I lose any hair or sleep over it.

Any more advice of course, appreciated, but if it a matter of waiting, I really don't mind. Thanks again.

Yeah it may help a bit. But just be wary as repeated disconnections are likely to make BT think your line is having stability problems, so if you can keep them to a minimum and try and get a stable, constant connection for 3 or so days and do another speed test and see where your at.

[BGN]

Okay, thanks for the tips.

I'm not going to miss the internet connection much next week as I will be very busy away from my PC for most of it. I just hope it sorts itself out sometime soon, I'm addicted to Call of Duty 4 online.

I'll 2nd that!

With such high attenuation, you must be some distance from the exchange. Sync is okay, if a little low, but I suspect your target SNRM has been adjusted by the exchange in response to instability, hence the sync is a bit lower than it could be. This is what is causing your poor throughput at present; due to this instability, your profile has dropped. In 3-5 days, it will reset and your speeds will return to normal.

The exchange will generally deal with your line by itself, so you can leave things alone and they should return to normal. In, say, 5 days, if things aren't back to normal, let IDNet know and they'll get BT to reset the profile manually.

What troubles me, BGN, is your upstream margin, which is very low. I suspect that your true attenuation is greater than 63db, but the router can't report a higher figure. Adding extensions on a line like that is not helping, particularly if they are flat extensions. It would definitely be worth trying at the test socket (behind the faceplate if you have an NTE5 master, the type where the bottom part of the faceplate can be removed) or master. If you don't have an NTE5, unplug everything else when you test. You are looking for the u/s noise margin and d/s sync speed to increase.

[Sebby]

That's a point. I managed to miss that in my tired state this morning. The test socket is certainly worth a try before contacting support.

Anything after midnight is forgiven, Sebby.
