I assume that you mean D8500.
&nbsp;
What do the LEDs on the D8500 look like?
&nbsp;
The manual tells you what they mean.
&nbsp;
If you visit the support pages:Support | NETGEARyou can feed in the model number and find the documentation, and, if there are any, firmware versions and drivers for your hardware.If you reset the thing and use the setup wizard, it should find the settings for BT.

Hi sorry yes its the 8500&nbsp;&nbsp;The twisted light remains red and has the message when trying to use the wizard that the dsl cable is not present, I have connected the dsl cable to my old BT hub and it all works well and connects however the D8500 will not recognise that the cable is present. The previous owner only used the router as an access point so never tested the modem side of the router. I suspect that the modem side of the router is defective.&nbsp;Thanks in advance for looking&nbsp;

That amber light tells us that it is not "not connected to a DSL service, did not establish a DSL connection, or did not establish an Internet connection". But you knew that anyway.

Aha,&nbsp; so we are talking second hand.
&nbsp;
I see no indication that you have done a factory reset on this thing, as suggested earlier. You should do that to wipe out any memory of previous internet connections.
&nbsp;
You don't say what the power LED looks like. I did ask "What do the LEDs on the D8500 look like?"

&nbsp;

Your firmware is corrupt. That's what the red power LED means.
&nbsp;
There is more severe, recovery reset, that you could try:
&nbsp;

Press reset for 30 seconds
Keep pressing reset while removing power
Keep pressing reset for another 30 seconds while apply power

&nbsp;
If that fails, you are into TFTP country.

This isn't the easiest operation, so if you are forced to use it, you could try a web search to find videos that&nbsp;guide you through the process.
