Internet Connection Dropping out!

[itgremlin]

I am getting a problem where my internet is dropping out.

so far i have changed the following:

routers
microfilters
laptops
desktops


i have checked the logs and im getting this showing up everytime its dropped its connection.

Oct 17 2008 12:07:03 im_backend:Changed ipwan IP address to 0.0.0.0

Oct 17 2008 12:07:13 im_backend:Changed ipwan IP address to xx.xx.xx.xxx (x = my ip address)

i have read somewhere on here that i need to change my idle time from 10 to 0 but i have already tried this and its had no effect on the problem at all.

i use a Static IP Address given to me by tiscali from the beging could this be the problem my ip is being used else where, sorry im clutching at straws here, i have posted on the support forums at tiscalis homesite and im still awaiting a fix !

hope someone can shed some light on this subject
thanks

Hi Simon

Not really a reply but I have a problem with Tiscali in as much as when a telephone call is either made or received my noise margin dips from 15db to -5db.

Still awaiting a satisfactory reply from Tiscali !!!

That's more than a dip, that's a steep plummet.

I assume as you're pinning the blame on Tiscali that you've eliminated your internal wiring and filtering etc?

Hi Chaz

Thanks for the comment.

I use the incoming LJU3 with an adsl filter.

The problem started on October 5th my adsl connection was not affected at all before then.

I have tried 2 modems, two telephones and 3 filters and all give the same effect i.e. my adsl connection drops out after app 8 seconds as regular as clockwork

Sounds like you've done your homework on that then. It could very well be a creeping SNR problem but nonetheless I think you've eliminated your side.

What happens if solely with the modem connected you call the line number from a mobile without a handset connected?

Hi Chaz

Surprise surprise my noise margin is now 21db and on hanging up the phone it drops for about 5 seconds to 16db.

The adsl conection remains solid

Has someone actually done something.

Will keep the forum posted

There's still a big drop there of 5dB which if your line was being pushed to its norm max (BT land say 6dB for stability) it could potentially force a resync.

I'm not on ADSL currently but from memory picking up the phone didn't make 5dB of diff!

An update as promised.

At 20:00 yesterday the line reverted back to the original settings complete with dropouts, and is the same this morning.

I also received an e-mail from tiscali in very broken English which told me absolutely nothing.

Will keep you all posted

Looks like my original problem is that Tiscali themelves are having problems with there Static IP range, i have requested a new one but there computers keep generating the same address and they keep asking me to retest with that address when i know that it has a problem due to the fact that when im on a dynamic range it works fine!!!! why cant their computer generate a new address for me aaaahhhh

A final update

After a great deal of prodding Tiscali finally stopped there silly questions and contacted BT.

The fault was found exactly where I predicted some 3 weeks ago to Tiscali.

It was in the local roadside cabinet.

I now sync at 7808Kbps with a noise margin of 14db

I am at last a happy chappy after 5 weeks of problems
