Range Extender firmware update

[CiprianoMPA]

I'm trying to upgrade the firmware on my EX3700 Range Extender.  When I download the file my Mac says that I can't open it.  It's a chk file.  The Netgear website is not helpful with trouble shooting and it says I need to pay for customer support.  What can I do?

Hi @CiprianoMPA,

                              You should not open the downloaded .chk file. You need to login to extender using mywifiext.net from a device connected to extender, goto "firmware update" in left, browse the .chk file and upload it.

Thank you.  I'm not able to open that site though.  Any idea why?

Hi @CiprianoMPA,

                              Try mywifiext.net from a device connected to extender's network. If that doesn't work, use the IP address of extender to login which can be located in attached devices of your router.

Sorry I'm new at this.  What is attached devices of my router?

Hi @CiprianoMPA,

                              Attached devices is list where it'll display devices that are connected to your router. Options to navigate to that will differ from router's brand and model. What is the make and model of your router? By the way, did you tried connecting a device to extender(_EXT) network and tried accessing using mywifiext.net?

Thank you.  I'm still not sure where to find this list though.  Is attached devices on the website?

Hi @CiprianoMPA,

                               Did you tried connecting any device to extender's(_EXT) network and attempted mywifiext.net?

[CiprianoMPA]

Yes and it tells me that I'm not connected even though I am.

Hi @CiprianoMPA,

                              What happens when you try mywifiext.net?
