I had to revert to 384_4_2. The network client list would constantly refresh. DirecTV would lose its Internet connection within 30 minutes after resetting the cinema connection kit's client. We have Cox Gigablast service and performance would slow to a crawl.
None of these issues were present, or were not as far as this addled dolt could discern, with 384_4_2. It is stable, fast and no constant client list refreshing. Oh, DirecTV has not lost its Internet connection since reverting.
My setup is pretty vanilla. I use bandwidth monitor to keep a fire stick from using too much of it. That was before switching to Gigablast. That's it. Vanilla after that except for IPv6 & manually assigned IP's.
