R7000 - no firmware update available

I'd like to thank the 3 of you for your input. Each of you provided some useful informaiton but Portwey84 was the most helpful. 

I had no problem downloading and extracting the update ZIP from the site which was done before I posted to the Commuity. 

I have not updated firmware on this year-old router before but have updated many other devices without as much grief as this one. The User's Manual didn't seem to have good suggestions beyond strict do 1, 2, 3, etc. There was no clue as to the use of the .chk file.or other 'error' messages that popped up. 

I was finally able to get thru the update process today with a number of wrong guesses on the way. To me it is far from strightforward. 

Thanks for the heads up about the auto-update process. I tend to prefer the 'let me do it manually' option so I know what's going on.
