Need to connect to new wifi WN3000

[jema2]

I have a sling box that does not have wifi built in so I purchased a Wifi extender to be able to use the sling box.  It automatically named the Ext my wifi name with a .ext after it.  I have had to replace the wifi and now I can't use the sling box because it is saying it is not connected to the internet.  I think I need to change the name of the netgear extender to my new wifi with the .ext after it but I'm not sure and not sure how I can change the name.

Reset the extender to factory default and reconfigure. Find your extender documentation under support - https://www.netgear.com/support/
