Posted: Sun Aug 29, 2021 9:47 Post subject: CTF for Access Point?
For a secondary router setup as an access point, does the ctf option do anything? Since NAT is disabled, I guess it does nothing? The AP is used for both lan and wifi connections.
The primary router has ctf and fa enabled. Both devices are R6300v2's.
Edit: Both running r47256.

In my testing CTF does indeed change how the wifi driver acts speeding up some clients slowing others. I don't understand why because it makes no logical sense. There is a very long wifi article linked to in this thread:
I do not believe that any wifi protocol at this time is fast enough to even come close to overrunning the CPU in a Netgear R6300v2 so if CTF acted logically it would not make a difference. But CTF doesn't act logically, or at least, not by what logic we understand of how it works.
When I dove into CTF I thought initially that Broadcom had implemented it -entirely- in software and that the FA code was using hardware acceleration. But I am not so sure that is the case anymore.

Thanks for the link and the perspective. It looks like enabling CTF on AP's, for my old router at least, doesn't really do much (or it does *shrug* something differently and doesn't break anything).
Since the option to enable it is present I'll just leave it enabled. With or without the option it seems I've maxed out my wifi speed anyway for both the router and clients.
I'm happy that CTF + FA is working well on the primary router and taking advantage of my fiber connection!
