   _Which_ "Devices"?  When you do what?  Do these (unspecified)
"Devices" get IP addresses?  Are they connecting to your (unspecified)
router?  Other devices _are_ "connecting to internet"?

   A vague description of what does _not_ happen is less useful than a
clear description of what _does_ happen.

   To what, exactly, are your "the adapters" connected?  What, exactly,
is connected to what, exactly?  (Hint: If a device has different types
of ports, then "connected to device" is not enough detail.)  Is there a
router involved someplace?

   Often a good start:

   Visit http://netgear.com/support , put in your (actual) model number,
and look for Documentation.  Get the User Manual (at least).  Read.
Look for the LED descriptions and "Troubleshoot".  Further reading might
not hurt, either.
