Sorry for the delay.
Router is Edimax AR-7024Wg
When I go to http://10.0.0.2 I am told that the web page cannot be displayed.
again sorry for delay
I assume this is the main router as my laptop is sitting right next to it and getting a good signal.
Apologies. Same gateway no. 220.127.116.11
It goes straight to Technicolor TG582n
I have a wireless laptop and no means of connecting it to the second router.
I have a Dell XPS with no cable to connect it to a router.
I assume that when undertaking your instructions it was going through the main router.
