R7000 is now primary, with DD-WRT as a real-world test. Remember these (frankly stupid) hacks:

CTF - enabled
CTF+FA - enabled (through override; may do jack)
CPU overclock to 1200MHz

During this test, I ran a bufferbloat test, then two speed tests immediately after. Router crashes. Well, I have to recreate this, and sure enough, it crashes again.

I then relocated to the stable router, upgraded the firmware to version r51043, built on 2022-12-19. Recreated the test issue again, and this time, it didn't crash. Very odd. This needs more testing, and it wasn't caught during the initial runs. This lived through four connected wireless devices and a Twitch stream; and was caught when ~10 wireless devices were connected.
