Looking for last firmware update N300RE WiFi Range Extender

[BJ_Lewandowski]

I have an On Networks N300RE WiFi Range Extender, Firmware Version V1.0.0.10_1.0.63 , GUI Language Version V1.0.0.10_2.1.9.6 .  I think there is a Netgear N300RE WiFi Range Extender as well. Do they have the same firmware updates?  A few years or so ago, updates to my sister's iPad and MacBook Pro caused them to have trouble logging on to the extender's WiFi, then eventually not at all (they ask you to provide the password for the WiFi name, but just won't sign in).  Where can I find the last firmware update?

that extender is a little known device sold to on networks directly. Unsure if the hardware is the exact same or if any other firmware would work. 

One thing you can try doing is factory reset the extender and reinstall it using the installation assistant and NOT using wps.
