That light should be solid, whatever color it is. Reset the extender.
With the extender powered on, use a pen or straightened paper clip
and hold down the reset button on the back of the extender until the Status light (the one on the middle)
flashes. After a minute or two, look on your tablet for a wireless network called NETGEAR_EXT
and connect to it. (you won't need a password)
Once connected, open the browser on your tablet and go to www.mywifiext.net
That should open the extender setup wizard which will walk you through connecting
to your wireless network. You will be asked for your wireless password ***** make sure to have it handy.
You don't have to use the tablet. A wireless laptop or PC will do as well.
Try to have the extender as close as possible to the router when setting it up.
