Admin login times out

> Cannot access router admin page from my wireless laptop. [...]

   "Cannot" is not a useful problem description.  It does not say what
you did.  It does not say what happened when you did it.  As usual,
showing actual actions (commands) with their actual results (error
messages, LED indicators, ...) can be more helpful than vague
descriptions or interpretations.

> [...] Tried the app and even Genie app [...]

   Which app is "the app"?  What happened when you it/tried them?

> [...] What am I missing here?

   A useful description of what happens when you put that URL into your
(unspecified) web browser on your (unspecified) computer/device?
"Cannot", "can't", and "would not allow me" all suffer from the same
lack of useful information.
