hey mouser if we reach 12,500 dollars are you going to raise the bar again?
It is exciting!! Go go gadget newsletter!
Dare we hope to actually reach the final goal ?-mouser (March 29, 2009, 01:34 PM)
Perhaps what we could do is have the forum software more clearly note when someone is about to reply to and revive a very old thread, making clear that they should only do so if they have something to contribute.-mouser (March 26, 2009, 07:21 PM)
Just from the symptoms you're describing, (barring a hardware fault with your ISPs DSLAM or the router), my vote goes with a cable fault of some kind.
I don't know if your ISP is also your telephone service provider, (TSP), but I'd be reporting a fault on the line of "intermittent disconnection" for your phone calls to your TSP, at the very least it should cause your telephone line to be tested from the exchange for faults such as Low Insulation Resistance (usually caused by rainy weather and poorly weather-proofed cable joints), High Loop Resistance (usually poorly done cable joints) and Excessive Line Capacitance (too many phones plugged in or some idiot has paralleled it with another unterminated cable pair).
If your TSP is really on the ball, (or at least halfway decent), they will also send a tech out to check the wiring connections at your house and check/change the phone.
The fault you're reporting isn't exactly true, (ie. it's happening on the ADSL not the phone), but since your ISP is absolutely useless, (they should have reported a possible cable fault to your TSP), then I'd have no compunction about reporting a fault on your telephone.
Just do not let the telephone people know that the fault is really to do with your ADSL otherwise you'll probably get charged a callout fee, (that's if you aren't already, here in Australia it depends on how much you pay per month for the service as to whether it includes free fault repair).
If they send a tech out, get friendly, offer him/her a cuppa and ask questions about your service like you're interested smiley (Unless they're the uncommunicative, "P!ssoff, I'm working." type.)
eg.
Is my phone line copper all the way back to the exchange?
Just out of interest, was my line within acceptable limits for Loop and Insulation Resistance?
Where is the exchange, I don't remember ever seeing it?
From the brief visit I recently had to Chile, I found the people to be rather helpful. Of course, I was a tourist blundering about not someone who actually helps to pay their wages.
Won't make a difference, those are purely the figures from the line side of the router back to the exchange - it doesn't take into account anything connected via WLAN or LAN.
Not knowing what type of plug/socket they use in Chile, the best/easiest way would be to (un)plug the plug half a dozen or so times, this is normally enough for a decent "clean" - more than I usually do.
It woud be interesting to note whether it was reporting any errors and if that count kept incrementing.
BTW, did the ISP provide the Zyxel and still they own it or did you actually buy it as part of their package ?
!
Well, from may of last year, but it hadn't been discussed here, and Mouser's earlier article was the only thing that clued me into it... Thought it was worthy of discussion at least, and that perhaps someone else hadn't seen it.-wraith808 (March 18, 2009, 10:36 AM)
hopefully we will reach the new goal
The 'noise margin' and 'output power' are fine however the 'attenuation downstream' is, to put it bluntly, crap. A figure of 56db means you're receiving just under 1/500,000 of the signal strength as sent from the ADSL equipment in the exchange.
That's their head office - where they hide, charge you money and provide little support.
If your internet connection was provided from Santiago you wouldn't have any internet at all - the maximum effective distance at which ADSL1 can be used reliably is about 7-8km. ADSL2(+) can extend that a little but not much.
Your ADSL connection is provided over your phone line from the local telephone exchange to your house - somewhere in your town there will be a rather drab building, (or possibly in the back of the post office if the building is big enough), marked Telephone Exchange. Someone around town should be able to tell you where it is, (Police, Fire Depart., etc). When you find it, measure the shortest distance between it and your house on your bike or in your car, (the actual distance the copper cable runs will be longer). Or just ask the company who provides your phone service how long the cable run between your house and the exchange is - you might get someone helpful who'll tell you.
Depending on how far away it is will help determine where the problem might lie, (eg. if it's <3km then the fault is possibly crappy wire joins or faulty equipment).
You could try unplugging the phone line from the back of the router 3 or 4 times to clean it's connection, the same where the line from the router plugs into the box on the wall. Plug/socket connections tarnish over time and that can introduce resistance into the circuit.
It could be that the ADSL filter itself has developed a fault or that any joins along the length of cable from the box on the wall all the way back to the telephone exchange have gone high resistance
No problem.
One other thing, on the Maintenance->System Status page there's a button marked 'Show Statistics', click on it and watch the stats for the WAN Port - ideally you don't want to see any Errors there.
