I just read the post with the same subject further down, I have exactly the same issue.

Attempted to upgrade firmware from the web interface of a newly reset router. Seemed to go OK, asked to reboot, never came back again.

I just have the square of solid lights with DSL not on.

It wont go into TFTP mode, the ethernet ports don't light up so the PC doesnt even get a link up. I can't ping it using a static IP when apparently in TFTP - the left 3 lights do go on for a minute or so when I do this, then it clicks and goes back to the square of 8 lights.

Can anyone help please?

Are there any Draytek engineers in this forum who support these devices?
