Mi ex6250 no puedo hacer reset

In inglese per favore

 

Netgear has set up a community forum specifically for the WiFi Extender products. Most of the people who watch that forum are more likely to have experience with WiFi Extender products and know how to work it better than those of us who follow this router forum. Might be more likely to find someone who has a solution if the question is posted there:

Thank you.

You can try recoving it with tftp or nmrpflash.  

are you on windows? if so, follow this guide

https://kb.netgear.com/000059634/How-to-upload-firmware-to-a-NETGEAR-router-using-Windows-TFTP

 

just make sure you enable tftp

and here's a video walk through using a tftp client. Use the built in one for windows 10 though. the video is more of an example of how its done.
