WHAT THE H*LL?????

AvengerUK · Mar 31, 2007, 14:20:46

Ive just got up/in etc, turned on, my routers been on all week by the way...and...

Im sycned at 352kbs!!!!!!!!!! it was 2500 odd yesterday!!! - download speeds are at 200kbs, and uploads normal - my upload is faster than my download currently. I cant use my net with such a low speed! My stats are: 58 ds atten as usual, but my SNR downstream seems fixed at 10!!

Anyone have any suggestions? its too slow to use!

Just forced a resync - now at 1300 odd, yet SNR still at 8....what the!

Should note profile is 200kbs or something like thart.....

Have you managed to do a BT speed test, Avenger? It sounds as if something triggered a really low sync which has hit your profile, but on top of that, it sounds like you have an on-going sync/line issue which has possibly pushed your target noise margin up. The lowest official profile is 500kbps, but there is a lower one of 279, that would only be triggered by a sync speed below 576kbps, which seems to fit with what you're seeing.

I've been sitting on a 10db margin since I lost sync yesterday, which makes me wonder if the recent round of DSLAM firmware updates has changed the behaviour of DLM?

All I can suggest is that you do the normal 'test socket' check and, if that doesn't alter things significantly, give support a call on Monday.

It gets worse....

160 kbps / 448 kbps

Downloading @ 50kbs....

Now, where did i put my dial up modem?

EDIT:

Then resync, ds atten changes by 2 - 56 to 58 to:

1888 kbps / 448 kbps

Something is obviously "up" with my line, with something else taking it down to obsene syncs sometime during the night :/ (there is a period of 30mins where my l8nc graph shows no active line at 1 am)

Rik · Apr 01, 2007, 13:41:01

Grim reading, Avenger. Have you been able to check at the test socket?

AvengerUK · Apr 01, 2007, 15:15:21

I havent yet rik - i might later before i log off - as thats when these really low syncs occur for some reason! (11pm - 1am typically they start, then last?)

Rik · Apr 01, 2007, 15:37:57

I've been seeing quite a few disconnects around 1am and 4am myself. I just wonder if it's some form of engineering activity as it's well after the peak hours?

AvengerUK · Apr 01, 2007, 21:46:24

noise margin downstream: -1 db
attenuation downstream: 58 db

That looks promising...lol

Was that a test socket reading, Avenger?

The signs seem to be pointing towards you going back to fixed rate, but it will be interesting to see what support have to say.

SteveS · Apr 02, 2007, 12:07:12

uho. is this a idnet issue or bt?

AvengerUK · Apr 02, 2007, 12:13:00

Line issue - so proberbly neither!, but definatly not IDnet

SteveS · Apr 02, 2007, 14:11:47

thats ok then

AvengerUK · Apr 02, 2007, 15:39:43

Update: pings are going "all over the place" - and packetloss, is, well, very very high.

Pinging BBC only 2 hops out of 4 get there!!

Speeds are still dismal...going to email idnet again and ask to go back to fixed.

Rik · Apr 02, 2007, 15:44:26

I was wondering whether that was going to be your best bet.

Max still seems to be something of a curate's egg, sadly.

Just checked, my ping times are +20ms over normal.

AvengerUK · Apr 03, 2007, 13:25:20

Update:

"It could be a line fault however as the connection itself doesnt appear
to be dropping its going to be difficult to diagnose. Please could you
monitor the connection to see if you can determine any pattern to it,
can you check the router logs to see if the SNR is raising to a point
then plummeting?"

Today dl speeds are up to 700kbs - so definatly usable now

Question is, do i bother "keeping" an eye on it...or just go to fixed? my router loggs dont show SNR changes anyhow!

Rik · Apr 03, 2007, 14:18:25

Will Routerstats work with your router, Avenger? I wonder if the app could get the figures (afaik, most routers don't log noise margin changes). Failing that, support can look at your connection and get the figure. Is there anyone who could lend you a different router to try?

AvengerUK · Apr 03, 2007, 14:25:00

Theres myself

I have the following avalible:

USR-9003 - this hates max...
Safecom 4114
Safecom SART2-4115

The two safecoms are great routers, however i dont think they log it either!

everyone else i know either also has a safecom or doesent use a router at all!

Rik · Apr 03, 2007, 14:32:32

It might be worth asking support if they could lend you a router...

AvengerUK · Apr 04, 2007, 11:53:39

do you know of any routers that let you do this?

Rik · Apr 04, 2007, 12:05:01

Sorry, Avenger, I'm not sure what the question refers to?

SteveS · Apr 04, 2007, 12:13:04

my netgear dg836pn shows noise level and line att

So does my BT 2100 Voyager, but I thought they all did, shows how much I know..

Rik · Apr 04, 2007, 12:30:02

I thought they all did too, Inactive. Sometimes, it's just finding out how to get at the information. Netgear DG834s and 834Gs certainly provide the answers, and, afaik, so do Speedtouch.

Lance · Apr 04, 2007, 12:32:39

My router doesn't log the SNR, but it does display it.

As long as your router displays the information in a webpage, you should be able to use RouterStats to log the SNR.

AvengerUK · Apr 04, 2007, 12:52:24

Ive Google'd Router Stats but cant seem to find it?

EDIT: http://www.vwlowen.co.uk/internet/files.htm

That it?

Anyway, Thanks guys - ill see if it works with my router tonight!

Rik · Apr 04, 2007, 12:57:00

That's the one. It's listed in the sticky here.
