Hello all.

I am seriously banging my head against the wall with this one.

For some reason my modem will only connect to the internet if I go on the phone. Hence, dialing 137 and leaving the phone engaged to go online. This creates the problem of people not being able to get in touch with me through my home line, and having no answer machine makes things worse. Its like im back on Dial-Up.. Also, having the phone engaged is not fool proof, my connection will sometimes drop when doing this.

Has anyone encountered this problem before, or does anyone have any suggestions? If so, please help.

Thankyou in advance.

Rawr.

Do you have ADSL filters on every phone in the house?

Its all quite possible, and all depends on what impedance to the line your phone offers with off or on hook. What is more important to understand you dilema in the first instance, is what DSL filters have you got and where are they installed.

Faulty modem? Perhaps the modem impediance is wrong (damaged) and when you lift the handset then you get the correct impedance on the line to allow the modem to connect. Or faulty line filter. Or faulty wiring.

You can never have enough Volvos!

I got a full installation done when I signed up with telecom, and if I recall, the maintenence guy commented on poor wiring? Anyways, he ended up putting a splitter into every phone jack I had.

And the modem I am using at the moment is borrowed from a friend due to problems with my old one.

Putting a filter into every jack is just dumb! as it does not get around the stub effects of various parts of the house wiring. Is there any reason why a new direct cable could not have been run from the demarc or first jack to the site of the DSL modem?

The only real way of isolating your problem is to connect directly at the demarc (or as close as possible) with all the remainder of the house wiring actually disconnected from the point on. This is exactly what a correctly installed central filter will achieve.

A normal "isolation test" which means removing all phones may not actually prove a lot as if you have a filter on each jack, as you have already achieved that, however you dont rid yourself of reflections from every end point of the line from effecting your DSL signal. Further, in some cases it could be that looping a line(lifting the handset) on one jack may provide a reduction in reflections from that jack that just let the system work.

Sounds like you are on a long line from comments you made earlier, in this case a correctly installed single central filter installed as close to the demarc with direct line (either new cat3 or cat/5e) from the splitter to the modem is the only way you can be sure you house wiring is upto supporting a distant line.

You cant do a true isolation test with the lack of real demarcation points on telecoms network, without cutting wires which means you need scotchlocks to restore the connection.

If you have wiring maintanance, then call telecom and log a fault with your phone, or call the ISP and have them log one.

You have tried 2 modems, so its not the modem, try unplugging everything you can from the line, and if its still not working then its not your problem (unless you had bad luck and 2 dud modems) so they wont be charging you for the visit.

Its probarbly a dodgey connection on the line somewhere and it needs the current of an active phone call to bias it enough to get signal flowing properly, and that is not your problem.

You can try opening all your sockets and using a proper punchdown tool on the terminals to check they are all in properly, but again, if your paying wiring maintanance, get telecom to pay a guy to come and do it for you.

No disrespect, but are you sure only the modem is plugged into a modem outlet and only phones into phone outlest?

I've come across this before and it can come down to a bad wiring job on the phone connection. I've had someone wire their modem line series with the phone which meant that when the phone was in use the circuit was made which allowed the modem to connect, and when the phone was hung up it broke the circuit.

might pay to get telecom/chorus in again to check, but for sure the full install is still the way to go..

Hi...I was here only 1 minute and noticed this thread, so for your interest...
I am living in a rented house.
About 6 months ago I remember the internet was not connecting with the computer. When I found the wireless telephone off the hook then returned it to the wireless dock the computer internet connection with resumed.
According to the XH1169 DSE router software the download rate is around 670Kbps and the upload rate is around 600Kbps. Slow for full speed broadband.

Hi Nickolas, welcome GZ, no that sounds slow, can you post other details from the modem stats, such as attenuation and S/N (or noise) and stated connection speeds that the modem reports. Do you have any idea how far you actually are from your local exhange, this will help establish if any why there is a problem.

There is a firmware upgrade for the router from DSE but in the release notes only 4 changes are indicated and from what little I understand of the upgrade, I think I do not need it.

...this... Changelog
· Rel10v2: Fixed problem where installing Firmware rel10v1 disabled the router’s

USB interface.

· Rel10v1: Added support for XH1173 and XH1175 routers

· Rel10v1: Added Stateful Packet Inspection (SPI) Firewall

· Rel10v1: Updated Web Management interface

· Rel10v1: Increased maximum number of Virtual Servers allowed

· Rel10v1: Upgraded base operating system

...if you need to see more details you better tell me what not to show and what you need to see.

I have spoken with xtra when I was with them an telecom and xnet and have had a few line checks, each blamed the other...and I have been told where the nearest exchange is but I do not remember.
I am in Otahuhu near to Mount Wellington.

EDITED: hey, the CLICK HERE FOR HELP link in the router software page I copied and pasted leads to the geekzone home page...
