Faulty Router or Line too poor?

Hi all,

I have been using my BT voyager 205 router for the last few months with not much trouble. I am however stuck at 1mb (instead of 2) and this could be because my dslam is yet to be upgraded + I seem to have too poor a line for 2mb.

Anyway, on to the real problem. I have just got myself a D-Link dsl-g604t wireless adsl modem/router. This router has serious trouble sync'ing and connecting. When it eventually does sync and connect (can take from 1min to half an hour) I usualy only get at max about 5 mins before it loses sync again and I can no longer access the net.

Looking at the logs it repeatedly goes through a cycle such as:
carrier down
carrier training
carrier up
(then maybe a connection, but usuall....
connection terminated
carrier down
carrier training
carrier down

and so on.
sometmes connecting and getting an IP and letting me on the net briefly, but then losing the sync again (adsl light goes off then starts flashing again).

So from this, to me it looks like my line is too poor, but when i remove the d-link and plug back in the voyager, it connects back up fine. :roll:

I have tried upgrading the firmware on the d-link - same prob. I have also tried connecting the router directly in to the main "hidden" phone socket behind the BT master panel and...same Sad

here are the stats from my BT voyager about the line:

Local Tx Power: 11.75 dB
Remote Tx Power: 16.1 dB
Local Line Atten.: 49.5 dB
Remote Line Atten.: 30.0 dB
Local SNR Margin: 22.5 dB
Remote SNR Margin: 24.0 dB
Self Test: Passed
DSL Standard: G.dmt
Trellis Coding: Enable
Framing Structure: Framing-3

Does this seem too poor for the d-link? or is it that the d-link could be faulty?
incidently the ethernet and wireless functions of the d-link seem to work fine.

Any help or tips would be appreciated before i RMA the d-link to ebuyer only to find that router is fine and they charge me Sad

Thanks for any help.

as a follow up I rebooted the d-link to get an actual snapshot of the log. Any plus.net guru's out there can see what's up? (btw I have xxx'd out my actual ip)

Faulty Router or Line too poor?

Hi

I Have a D-Link router as well and getting this all the time.
It started about 4 or 5 weeks ago and even though I have reported and a 'fail' is showing up in plusnets checks at their end I still have had no response.

I know there are problems moving people to the new 8Mb lines but I have had no idication that they have moved me as yet

Don't know about D Link routers, but your downstream figures
Local Line Atten.: 49.5 dB
Local SNR Margin: 22.5 dB
are not really all that bad.
Mine are just a bit worse and I've been synching at 5.5Mb for quite a while now with no problem.
So whatever is wrong, it's not your line, based on those figures.
When you go Max, the SNR should decrease as your speed goes up, till it's down to about 6dB, and it should stay there.

Sorry to hear of your troubles.

I'm using the G604T and it works well with our 8128 MAX line.
firmware HuhHuh.??.815

Hopefuly someone with a MAX line and a G604T who are syncing at less than 8128 will turn up for you.

Try disabling Bridge mode.

deck7uk,

I have a DSL-G604T also, and it is completely failing to connect at the moment, (possibly due to the MaxDSL upgrade).

I wonder which version of the firmware you're using, and how you managed to extract such a detailed log from your D-Link, as it never seems to give me such valuable information... (are you using remote log?)

On the DSL Network Stats page, it shows that it has sent plenty of data, but received nothing, even after several reconnection attempts. Could the router be faulty?

How do you determine the sync rate with the D-Link?

Regards,
Matt
