You can check the firmware in the network page of each tuner as well
I got burned by that recently. I had a tuner that was having lots of issues and it was displaying 1.16 on the web page (both of them were). I had checked it MANY times. At a VM tech's recommendation, I tried updated the firmware anyway and the upgrade tool reported that the tuner was actually at 1.14!
