IP Profile Falling

ST Driver · Jul 04, 2008, 18:48:18

Hi
Does anyone have any idea why my ip profile should have fallen by 1000K in a month.

I have had no more than the odd resync, than when I joined in Jan when my sync was
a solid 8096. Now it seams to sync at 7235 or less until I restart my router.

My router stats for 03/06/2008 and 04/07/08 are below

03/06/2008

IP Profile 7000K

Stream Type


Interleaved Channel Data Rate
Up Stream 448 (Kbps.) Down Stream 8096 (Kbps.)




Noise Margin
Upstream 26 dB Downstream 8.5 dB


Output Power
Upstream 11.5 dBm Downstream 20 dBm

Attenuation
Upstream 21.5 dB Downstream 35 dB



04/07/08

IP Profile 6000K

Stream Type


Interleaved Channel Data Rate

Up Stream 448 (Kbps.)   Down Stream 7616 (Kbps.)


Noise Margin

Upstream 25 dB   Downstream 10.5 dB


Output Power

Up Stream 11.5 dBm      Downstream 20 dBm


Attenuation

Up Stream 22 dB Downstream 35 dB



TIA

Hi Steve

The figures suggest you've had more than one disconnection, your noise margin has been increased and your profile is lower than it should be for the current sync speed. Does your router log disconnections?

Sebby · Jul 04, 2008, 18:52:50

What Rik said, although I must say that your SNRM doesn't look particularly high. The target could well still be 6dB. That said, with attenuation so low, you should expect full sync.

Could you reboot the router now and repost the stats straight away?

Hi

The stats for today were taken at diner time today straight after a reboot, as I lost ppp just after
midnight. this was the first time this had happened for 4 or 5 days. If I loose ppp it will always happen
during the night, this has always been the case since I got adsl 4 years ago.

That's normal, Steve, ADSL uses the MW radio frequencies, so noise is highest at night. If you then re-sync during the day, you'll get higher speeds but less stability.

Have you removed the ring wire from all sockets? Do you use an extension lead to connect the router? If so, is it flat or round?

ST Driver · Jul 04, 2008, 19:34:57

The router is pluged straight in to the main BT socket, thro' a filter.

The lead to the router is flat and only runs from the BT socket nd the router.

Over the last few weeks I have tried differant filters just in case.

Steve

Rik · Jul 04, 2008, 19:40:26

That should be OK, Steve. Do you have any other phone sockets? If so, removing the ring wire from terminal three on all sockets may give you a big boost.

Sebby · Jul 04, 2008, 19:41:38

Could you try the test socket (behind the faceplate)?

Rik · Jul 04, 2008, 19:43:31

Why didn't I remember to ask that?

Sebby · Jul 04, 2008, 19:45:52

It's been a long and hard day, Rik. You're forgiven.

ST Driver · Jul 04, 2008, 19:51:44

Rik. That is the only phone socket in the house.

Sebby. Will try the test socket and get back to you.

hopefully I will be back on my system by then and not using the wifes laptop.

Must go the boss wants her laptop

It has been a long day I was at work at 04:30 this morning so if I stop replying I will
have fallen asleep.

In that case, the test socket shouldn't make any difference as there are no extensions.

The only other thing it could be is a deteriorating line (physically), which there's nothing you can do about.

Hi
thanks for the help Rik and Seb. I will keep monitering things and and hope thing don't get much worse.
Still not as bad as F2S/tiscali

Dangerjunkie · Jul 04, 2008, 22:09:59

Have you tried a pro modem cable and a different router just in case either of those is "going soft"? How is the ventilation round the router and the temperature in the room? Could the router be overheating? You said you tried different filters what kind of filters are they and how old are they please?

Cheers,
Paul.

ST Driver · Jul 05, 2008, 20:11:52

Hi DJ

Both router and filters are about 4 years old. Will try a new filter the present ones are Belkin.

The router is also a Belkin and apart from an occasional hiccup it has been no problem.

A new router and pro cable will have to wait as there is no money in the kitty for them yet.

There is plenty of ventilation and it is cool as it is in the coldest room in the house

I'd seriously suggest the ADSL Nation xf-1e, Steve:

http://www.adslnation.com/products/xf-1e.php

I've never found better.

Sebby · Jul 05, 2008, 20:42:01

ST Driver · Jul 06, 2008, 11:36:33

Thanks I will get one next time I get paid

Steve

Sebby · Jul 06, 2008, 11:39:33

They're available slightly cheaper here, and with free delivery. I've bought from them before and they were quick to deliver.

Dangerjunkie · Jul 06, 2008, 20:51:58

Good luck

The good news about the cable is that they're only about £3 from www.adslnation.com for a short one.

If you think your router may be dodgy I would try to borrow one off a friend, someone on here or I once heard someone here mention that they thought support may have a loan unit.

Cheers,
Paul.

Rik · Jul 07, 2008, 01:27:07

I can always lend a unit, support will also lend one out.

ST Driver · Jul 07, 2008, 08:14:58

Hi
have got a router on its way from my eldest son should be here by the end of the week.

I have convinced the better half to let me get a new filter (which has been ordered) and
a new lead which I will order this morning.

When eveything is in place I will let you know the outcome

Thanks again steve

Rik · Jul 07, 2008, 09:17:35

We'll be here, Steve.

Dangerjunkie · Jul 07, 2008, 09:31:19

Hi,

Have you made any changes to your phones recently, like new phones, moving your cordless phone if you have one? (is it near the modem?)

Does every phone and anything else plugged in (like a fax or Sky if you have it) have a filter?

Cheers,
Paul.

ST Driver · Jul 07, 2008, 09:45:28

Hi DJ

No changes to phones only have one pluged into main socket thro' a filter
and the base unit is about 6 foot away from the router, the phone will be anyware
in the house but not on the base station, untill it goes flat.

If we need to pleg the sky box in it is with an extention lead that runs
across the floor and is put in a draw when not in use, and unplug phone to do so.
Sky box has not been pluged in for about 3 months.

Steve

Dangerjunkie · Jul 07, 2008, 10:00:27

Steve,

You have PM...

ST Driver · Jul 09, 2008, 21:20:31

Hi

good news after changing filter for an adsl nation XF-1e
and the standard flat lead for a twisted pair one this morning
my IP Profile has already risern to 6500K. Fingers crossed if I
can keep a stable connection for a few days I may be back
to normal.

So a big thanks again

Steve

Sebby · Jul 09, 2008, 21:32:34

I'm glad to hear that things seem to be more stable. Let us know how it goes.

Rik · Jul 10, 2008, 08:22:24

Great result, Steve. It's amazing the difference that the filter quality and last section of cable can make.
