EX2700

I was able to connect the Wifi Extender to my existing router.  I followed the advice that the extender should have a different SSID, which is to add EXT to the existing SSID of my network.  I have an Amazon Dot and the app was installed on my iphone connected to my existing network.  Amazon Dot was working perfectly until I installed the netgear extender.  Once the netgear is installed the iphone could now see the Extender as another wireless network.  If I connect to the extender, Amazon Dot cease to function.  What I did is I disconnected the extender for now and the Amazon Dot could now be used.  I have reset the extender and would like to set it up again.  Can I use the same Wireless network SSID without the EXT on the extender.  Would this solve my problem on the Alexa Dot?
