Firstly, I really appreciate you getting back.
Taking your instructions in order:
When I press and hold the reset biutton, the blue light never turns but it does when I trelease the button the follwing sequence happens:
red light
then red and blue
then red and blue flash
then they both go out
then the red light come on
then the red turns green
My router is a D Link DGS 1005D
The router web UI is a bit of a mystery to me but I followed instructions and put in my deafualt gateway 192.168.2.1 into my web browser.
I then get a page that seems to be dedicated to my Belkin WiFi router so I guess I am doing something wrong.
Does this mean anything to you. Sorry for my ignorance!
