I am having an issue with my ADSL staying up.

Each time I terminate a telephone call the router/modem, a TP-Link W8960N, drops the ADSL connection. I am pretty sure, but not certain, that nothing has changed with the hardware, i.e phone and the router, in the timeframe it has been going wrong. The only thing I think that has changed is that we now have ADSL+ as downloads are much faster.

The phone is incrediably unclear when used. It has a hissing sound when in use.

I am reasonably experienced with routers etc and known how to fit a filter.

Reading http://forums.whirlpool.net.au/archive/457901 it does seem that panasonic is a issue.

Is there anything else I can try to work around this?

Thanks,
Iain

Hi, you clearly have a filter issue, please explain what filters you have in circuit.

There is one filter on the telephone socket. The ADSL router is plugged in a separate socket with no filter. This has not changed in 10 years of usage accept for the filter which changed when I bought the modem/router where I used the one which was provided.

I have tried replacing the filter/wire etc with no joy.

My guess is that the introduction on ADSL+ has made this issue more obvious but I do not know enough about telephones to know this is the problem.

I run linux servers with 8 PCs on a network using 1 router and a switch. There are 2 iPods, 1 phone, 1 xbox and 1 PS3 running on the network also.

Any other suggestions.

Also, could the phones base station be too close to the wireless router?

Hi, so no other phones or sky boxs or alarm systems connected across the line.

Sounds like you need to get a master filter put in (Chorus will do it, or you can have a go yourself).

Have you tried a filter on the ADSL socket?

bibble235: .... This has not changed in 10 years of usage accept for the filter which changed when I bought the modem/router where I used the one which was provided....

So I'm taking a guess that it might be one of the older style Panasonic phones, similar to the following?

I had no end of issues with one in conjunction with my ADSL connection, with noise and calls also being exceedingly quiet. The quietness seems to be a well documented problem. I replaced it in the end, although weirdly it still works just fine connected into the back of a PAP2T for a VOIP connection.

Thanks all for your quick responses,

Yes I have a panasonic similar to the picture above. Mine is a Kx-tg1811nz

Phoen

And it is a pain in the neck.

1/ Will Telstra fit a filter for free?
2/ If not I am able to, where do you buy one?
3/ What phones work with ADSL+
4/ Is it possible to configure you way out of the problem with the router. I have several other wireless routers which I could chain if this is the problem?

Hi, the other guys have pointed out a good point, those particular analog cordless panasonics were a right pain the the rear, a very common problem, its time you got yourself a good DECT unit, and panasonic is a good brand even though this older unit was a problem with DSL.

Chorus will do all line work for Telstra DSL connections, but you must go through your ISP (Telstra) to organise one, however it may be cheaper to get a private data cabler to do it. If you a DIY type person and have modest wiring skills to install a filter is not too hard, PM me if you want a source for parts.

Exactly how many phone points do you have, if its just a couple and the wiring is simplified then you can save youself getting a filter by just configuring the wiring appropriately, maybe explain more.

Still googling and have more questions

It appears I have two options

A) Change my phone
1/ Does a DECT phone mean no more issues with dropouts?
2/ Does it matter which version of DECT
3/ Are there other things I should know before pricing a new phone (ideally a least 2 handsets)

B) Change my filtering
1/ What is the price of telstra fitting a filter all up?
2/ What is the price of parts for fitting it yourself?
3/ Are you legally allowed to fit your own filter?

Thanks all.
Iain

Hi, I recommend you stay with standard DECT rather than wideband DECT, both Uniden and Panasonic have a good selection of standard DECT handsets, panasonic are my preference, you can buy them in sets of 1,2 and 3 and you can add more handsets. They also support handing of calls between handsets. I am not aware of any modern DECT handsets upsetting DSL, but the older analog cordless units like you have are notorious for it.

Chorus will charge you $199 to install a central filter, I can supply the parts for around 25% of that. You are allowed to do wiring yourself although opening the demarc/ETP is not a good idea if you are not familiar with what you are doing.

Yes I replaced my old Panasonic analogue with a Panasonic DECT (two of them actually). Never had any issues with them at all.

Umm, you have now posted a picture of your phone, its not the same as the first one posted by allan, its a DECT one, and should not effect your DSL. Maybe try moving it away from the modem.

You are correct, as I now see, Just bought a Panasonic KX-TG1613 and this produced the same results as the original model.

It seems I am back where I started.

I.E. The ADSL disconnects each time the phone is hung up.

Is there any clues I can get from the TD-W8960N router which would help. The next firmware release says

Add supports of WEB ALG switch;
Add supports of 1500 Bytes MTU under PPPoA mode;
Fixed Chrome update issue;
Fixed Australia TPG PPPoE issue;
Fixed TCP MSS configuration issue;
Fixed Traffic Control needs reboot to take effect under PPPoA mode;

Any of these sound like an cause of the issue?
