I have an R8500 with the latest BS 42847 firmware. For the last few firmware updates, my wifi has stopped transmitting after installation. The Wireless SSID Broadcast in Wireless>Basic Settings is always set to enable.
For a while, I just left it. But recently, I found a way to get it working again, by installing a really old Firmware: DD-WRT v3.0-r30260 std (07/20/16), and then reinstalling my CFE. Method below...
I don’t know why the boot loader needs to be reinstalled either, but although the method above works, is there not something that will manually restart the WiFi radios or something? Maybe there’s a line of code or a script that is quicker to get things working again without applying this long method above?

The version DD-WRT v3.0-r42287 std (02/06/20) seems to be the last version that works with my R8500, in case that helps. I have tried pretty much every release since then and no SSID is broadcast on any of them.
nvram erase should be done after upgrading to a recent build.
If you do that on builds from 2018 or earlier the result is unpredictable
Thanks, I never knew this. But wouldn't the same unpredictable results, in any case, still happen after a new build with nvram erase as if I'd just done a nvram erase before updating? In my case, the wifi radio stops working in either scenario...
