Dlink 504t

[monty]

I use the Dlink 504T ADSL router, which is now about 3 years old. It's a Thai bought Rev. A3 model, still running ver 1.00 firmware.

So no ADSL2 or ADSL2+ support.

I have a 3Mbps/1Mbps connection, but on the uplink the SNR margin is very low (around 6 DB), so my uplink sometimes fails requiring the router to re-negotiate the connection. It also never reaches the 1024 kbps, but always connects between 900 and 950 kbps.

Basically I assume due to the uplink limit of the old ADSL standard (which I think is 1.3Mbps when sitting right next to the Dslam).

On Dlink Australia's website it states that their firmware upgrade (ver 2. something) will enable ADSL 2/+, so assuming the Dslam I'm connected to supports this, I should get rid of my uplink problem as on the ADSL2 standard longer distances should be possible with the same line quality.

Anybody done this? All the newer 504T's I've seen support ADSL2 out of the box.

It's just that the website states that the firmware should ONLY be used in Australia and New Zealand, also on the Singapore website it states that their upgrade is only to be used in Singapore and Malaysia!

I'd rather not brick it

Cheers

Hello Monty,

A firmware upgrade would be useless, in the 3-years that you use your modem/router combo nothing changed. Internet providers in Thailand still the same technology, and therefore upgrading your firmware would only give you the risk that something go's wrong and you make your mode/router useless.

If you use for 3-years the same router, why you not simply cancel the connection and open a new subscription, you likely get a new modem which is ADSL2 (and what more) compatible.

I believe that country specific warning is for the built in ISP settings. But that is only a guess. I just upgraded my D-Link 2540T without a problem and believe I downloaded from Singapore. It held all my settings.

Not necessarily I would think.

I know I'm connected to a micro DSLAM, which was installed just a few months not far from me. Pretty much all of those devices on the market are ADSL2+, so unless they had it lying in stock for 3 years, the device should be ADSL2+ capable.
