XR1000 What/Where is the Latest Firmware?

I have a XR1000 and my current firmware seems to be 1.0.64.18_5.0.19.

On the support page for the XR1000 under 'Firmware and Software Downloads' it says

"Firmware Version 1.0.2.86" with "Latest" next to it.

https://www.netgear.com/support/product/xr1000#download

 

Furthermore, I downloaded the XR1000-V1.0.2.86.zip, and when I extracted it, these are the files:

-XR1000-V1.0.2.86_2.1.40.chk

-XR1000-V1.0.2.86_Release_Notes.htm

 

According to 'Nighthawk Pro Gaming Router Model XR1000' user manual on page 151 it says

"Note: The correct firmware file uses an .img extension."

 

.chk files are usually recovery fragment files

 

What is the correct Firmware version and where can it be downloaded?

    Could you please take a minute to look at the product label (usually on the bottom of the case) to verify that this is not the XR1000v2 model?

  • The latest is the one you downloaded and you upload the .chk file to the router on the firmware update page

      Netduma-Fraser​ , the OP ATN90​ concern was the fact the user manual does not refer to a .chk file extension:

      All available XR1000 (and XR1000v2) firmware downloads ZIP archives come with a .chk file, we can safely assume this is an error in the documentation.

      Never conclude to the file content based on the file name extension...
