128772 2003-03-17 09:25:00 Thanks for all the thoughtful comments.

Been at it since before 4am and getting tired now.....will reply more fully tomorrow.

Before going, the latest episode:

checked the temperature of the Router by lifting it very gently to feel underneath...(kames' suggestion) - it was warm, well over 40C but has been since I got it. Power pack is too hot for my liking, over 50C I'd guess.

As I held the Router in my hands the Link LED went off and that was the end of my jetstream connection.

28 minutes later it came back to life, and I'll tell you tomorrow what I did during the downtime

g'nite all

128773 2003-03-17 20:13:00 Good morning to all

Last nights' brief outage of my adsl connection seems to have been triggered by my physically disturbing the quite hot Router to feel it's temperature, after reading Kame's post about CPU overheating. Highly suspicious........I wonder, do these complex electronic gizmos have a heat overload cut-out built into the circuitry? Could my touching it have set it off if it was at the very brink of it's temperature limit?

Lifted the still powered on Router off the desk onto wooden blocks and directed a strong blast of cool air from a domestic fan onto both the Router and it's very hot power adapter. Both soon cooled dramatically, but after 20 minutes the Router Link light was still off, and configuration page still reporting the usual "physical line error".

I should have gone to bed then, but being an impatient character and without nearly enough time left in this world to scientifically test all potential variables, I tried one more suggestion that I found somewhere on the web.......I unplugged the Router power adapter from the spike protected power box and plugged into its own mains wall outlet.

Powered up the Router and in less than 5 mins it had automatically connected.

Switched off the Router and went to bed....got up early,switched on, and within a few minutes the automatic connection was made.


Maybe someone will make sense of this sorry tale , I'd sure like to hear from them.

Until I can establish with some certainty what the problem is I wont dismiss any suggestions made, and will post anything useful to others here .

godfather......IP addresses are assigned automatically as per instructions

clueless......I have a 19 year old house with several additions to the original telephone setup. Might be something to look at, but the Telecom technician installed a splitter before the line reaches the other possible junk. I would have thought that would avoid any kind of interference from any problems after the splitter?

Billy T.....my phone master wall outlet has two red, one white and one blue wire attached to the female plug bit and other coloured wires of unknown origin lurking in the background.

Kame....you may have resolved the problem for me by raising the temperature issue....after D-Link (obviously), Telecom, and World-Net, this one will head my list of suspicions to be watched in the coming days.

While the "other junk" in your wiring can always be a factor, it sound like you have narrowed down the problem to something completely different. Seems a little rediculus that your router will require an exteranal fan. It also seems a little on the not too safe side of things, if regular overheating is indeed the problem.

I really don't think router temperature is your problem, and neither is the plug pack . Plug packs can get very hot, but as a general rule it doesn't affect their performance .

Fans are an interesting diversion but not particularly helpful . If you want to keep the temperature down a bit, you can temporarily improve heat dissipation simply by standing the router on one end to allow both top and bottom to radiate freely .

Subjective assessment of temperature is not always very accurate, so if it is a real concern to you, it is better to get one of those cheap indoor/outdoor electronic thermometers and tape the outdoor sensor to the case . I did this when I read that my first Nokia Ni500 was prone to overheating, but although the case felt hot, it never exceeded 35 degrees . The "runs cooler"replacement sits at around 25-27 degrees, depending on ambient temperatures . Internal temperature will stabilise after about an hour of operation and after that, short term thermal effects are unlikely .

The real answer lies in the performance when cold . If it doesn't work then, it is unlikely to be temperature related . Also, you mentioned that it came on after a long period and stayed up for 34+ hours . The reverse would be more likely if temperature was the cause .

Finally, your router and plug pack are not unique, therefore other users should see the same temperatures, allowing that there is nothing unusual about your operating environment, i . e . you are not working in an abnormally heated area . That makes temperture even less likely to be the cause . In the absence of a specific component failure, if one unit overheats, all will overheat .

It might be a silly question, but are you using the correct plugpack? I have so many leads lying around that one day I accidentally plugged the wrong one into a new device and it was only the fact that the voltage was too low rather than too high that saved me!

Finally, can your router be interrogated via a serial port/telnet connection? The Nokia can, and the diagnostics will record why the connection is down . If there is no serial port, is there any diagnostic software provided?

I forgot to ask, are your VPI and VCI settings correct. For Telecom they should be 0 & 100 respectively.

I still think your problem is wiring related and it sounds like your cabling is three wire. You could try disconnecting/unplugging every other device from your phone line and see if that helps. I also wonder if your filter and wiring to the router are correctly installed. From memory it is a straight through connection to your ADSL outlet and a low pass filter to the rest of your phones.

If Telecom installed a filter at the point of entry, you should now have a dedicated cable pair from that point to a dedicated adsl outlet. Logically that should be a new outlet installed at the time that the filter was fitted. All other phone services run off the other two wires out of the filter.

I don't actually know how Telecom handles this aspect of the installation because I had prewired everything and all they had to do was install the filter.

A description of your actually connection from the router to the filter is the one thing missing from this saga, and if it isn't a dedicated line with nothing else attached then that could be your problem.

This Thread (pressf1.pcworld.co.nz) gives more info on adsl filters and phone wiring. It will help you check your system if that proves necessary.

128778 2003-03-17 23:12:00 If it is working OK with the the spike protected power box bypassed isn't this indicating a problem with this unit. Jim B (153)
128779 2003-03-18 00:38:00 The presence or absence of a spike protected power box (or phone outlet) for that matter would have no effect whatsoever on the adsl reliability. Spke protectors are level dependent and do nothing until a major input overload appears.

128780 2003-03-18 01:07:00 well having eliminated the spike protector and after taht the system works.......its obvious to me that the spike protector is the problem.......test this easy by plugging it in again.....

if it continues to appear that the spike protector is the problem ......take it to someone who has a voltmeter and check the output from the wall socket then check it from the spike protector AFTER it's plugged into the same socket.........possible that somehow it's just not putting out enuf voltage.......

128781 2003-03-18 01:49:00 Hmmmmm..............I have some serious rethinking to do!

I'll get back to you all later.

In the meantime we are still jetstreaming away merrily here, and I'm hooked. Can't imagine life without it now :D
