RBS50 fails to update but RBR50 is successful
Hi,
So I downloaded the firmware from Netgear RBR50-V2.7.6.6 since the router does not find any new version besides the old I have which is 2.7.5.6, updated the main router and it worked perfectly, tried to update the satellite next, but it fails and I get an error message saying:
"This firmware file is incorrect! Please get the firmware file again and make sure it is the correct firmware for this product."
Ok so I tried to rollback the main router to previous version 2.7.5.6 thinking maybe you have to update the satellite first. Rollback worked no issues, tried to update the satellite again with newest firmware and still the same error message. So is this a bug or you simply can't update the router to the newest firmware, only the main router? Thanks for any help with this matter.
The satellite firmware file is different from the router firmware:

As FURRYe38 mentioned, I find it easier to connect to the satellite IP address and use the Firmware Update menu selection on the satellite itself.

What browser did you use? Try MS Edge or Firefox?
Be sure you update the RBS first using its web UI.
Clear out any browser caches.
File should be .chk.

Thank you! I looked for the satellite firmware but couldn't find it on the website only for the main one. I use Firefox and I log in to the web UI orbilogin.net. I use the satellite firmware window of course. I'll try updating and get back you.

Ok so CrimpOns firmware worked :). Both firmwares ended in .img but they updated fine. So thank you both for your help :).
Before I finish off, since I have two experts here I might as well ask if these settings below (see picture) are best for this router :).Edit: Ok so I am trying to upload a picture but it says "media upload in progress, please wait a few minutes" and nothing else happens. If I wait the page just reloads after awhile and both this answer and the picture I want is not there, tried uploading from computer and also as a file. So I will have to try uploading it later.
