Router connection issues with EX3700

I have been trying to reset my netgear ex3700 wifi extender.  I have reset the factory settings, set up the extender, updated the firmware on the extender and it keeps dropping the router.  I think it is may be tied to two odd things that happen but I don't have enough knowledge on how to correct.  The first is I go through the whole set up and confirm my device is connected to wifi through the extender by pulling up a browser and searching.  When I go back to the setup wizard to click the box and confirm it is connected, it pulls up a web page with my IP address and tells me it cannot reach the server.  The second is when I do try to connect to the exteded wifi network, it tells me the password is incorrect and I have re-enter my network password even though it was accepted during set up.  Any help would be greatly appreciated.
