netgear wifi extender question

i tried to put number in the products section it did not keep them   the only number i have are wn3000rp and wn3000rpv3 what else do you require?    so this is what i did just now. i plugged them in on the table and the on light and the light that looks like a candle that i found out is the wps so if that is on it must be connected to the router.v then the router light turns on. then the device light turns on and when i plug it into the lan network the arrows turn on. so i connect my phone to it as the phone saw it as an extender but i got no internet, 

i'm leaning on these being junk and even new would not work as described. and when i plugged them in my nvr came up with a ip conflict and the netgear gateway i had open to see the access control started failing and then i lost that connection. so i may have to do a reset on the extenders.

so is there a site that show how to set these up? i may just reset them and start fresh and see if they actually do what i think i need them to do.
