Hello! Two quick questions about the RE 450:

1. The 5g band drops regularly for just a second, then restores. I often get a "you are not connected to the internet" screen in the browser, but a reload and all is well. Is this normal? Any thoughts about cause? (Note that I can actually hit the 5g on the parent router without a problem, so I don't think it is distance.)

2. Related – What is the latest firmware for this model? The latest I saw on the support page was 2017-12-20, which I assume is what I have. (I see both a "ver. 2.8" and a 171220.)

Thanks!
