Right, now this is a bit unrelated and offtopic from the thread (although semi-related due to Driver related talks and what it's using) but I had opened up a threat on the forums here: WRT32X with 18.06.4 - 2.4GHz dies after a few weeks
And was told to try these drivers, but it was my understanding that they haven't really changed so I was curious and what may or may not be different between those drivers, Davidc502's builds, as well as Stock OpenWRT.
Now based on what @eduperez said above, it seems possible that Stock OpenWRT 18.06.4 may not be using these latest drivers or in the past haven't always been fully up-to-date, although that doesn't say for sure if 18.06.4 is using the latest.
