I have an Orbi CBR40 router that has the latest firmware, but my satellites (RBW30 & RBS20) are a couple of versions behind. I did not realize I had to update satellites first. Anyway, I followed the manual's instructions on how to update the firmware on the satellites manually. I download the correct zip files, extracted them, moved them to my desktop, and when I browse for the file and upload it, I always get an error message "This firmware file is incorrect! Please get the firmware file again and make sure it is the correct firmware for this product." I have double-checked and I am downloading the correct firmware file for the satellite I want to update. I am not a techy person so if you have any advice, can you please lay it out plain and simple, step by step.
