Looks to me as if your upload attenuation is quite high. Mine is about 30db downstream like yours, but my upload att. is only 14.7db. Yours is 45.5db. Not much you can do without getting your wiring looked at.

supernom · 1st January 2012, 8:51 PM

Normal, everything plugged in

Everything unplugged except router (no filter), I also disabled wireless on the router.

Not much difference

I'm pretty sure it's something with your line now, 45db upstream is not normal. If you're going to ring tesltra or whoever your ISP is, you going to need to try another modem. You've done well to go for isolation tests first.

I'd say that either the port or the modem has had the finger. lack of upstream CRC errors doesn't suggest noise, and the output power levels are normal. most likely the port has gone deaf and is dropping the lower end of the frequency spectrum, which is why the attenuation is so high/bitrate so low with no errors.

OP has apparently been a bad boy though, I can't even see the post he got canned for so I presume it's been deleted.

Lol I just have a 24 hour break.

I went onto adsl2exchanges and put in our ph number and address. Here is what it told me.

Line of Sight: 4473 m
Estimated Cable: 5144 m
Estimated Attenuation: 72
Estimated Maximum Speed: 1500

5 km cable.
Could this be the causes of the problems

??

Could be. But you still haven't given us the ADSL stats from your modem. I doubt there's much that can be done with that line length though.

FYI adsl2exchanges isn't 100% accurate. At my old place it said max speed of about 8000, we got more than that, and even more when the line was replaced. At our new place, it says we should get a maximum of 11000, but again we get more than that. 15600-16000kpbs.

Are you sure someone isn't torrenting with dodgy settings on the network? Your uptime is three hours and you've already uploaded 2.1 gig.

That doesn't even seem possible!

Oh, somehow missed that he posted stats!

As above. Lock down your network to you and your lan connection only for a while. Also report a fault with your ISP, no line should have 45db upstream. In fact, no line should have an upstream attenuation that is higher than the downstream one! For the record my down/up attenuation is 31.5db down and 14.7db up! Yours is way out.

supernom · 26th April 2012, 3:22 PM

So yeah finally got around to getting onto telstra about this, and after a few days of back and forth calls they have said everything at there end looks fine, must be a problem at our end....

These stats are as of right now

Considering forking out for a brand new router right now

Currently running on a different router, an old one we used to use back in NZ. Get the same results on speedtest.net

Some stats from this router

Code:

 
Item	           Downstream	Upstream	Unit
SNR Margin	6	           6	            dB
Line Attenuation	34	           45	              dB
Data Rate	12246	           434	            kbps

So I don't even know if buying a new router would make any difference

In an attempt to resolve our issue of net dropping out when the phone rings, I picked up 2 new adsl filters and plugged them in, but it did not solve the problem.

Does anyone know what else it can be ? We asked telstra about it and they said it is the faulty filters, but nope.
