Router Model & Version: Linksys WRT3200ACM
Firmware: DD-WRT v3.0-r47720 std (12/02/21)
File: ddwrt-linksys-wrt3200acm-webflash.bin
Kernel: Linux 4.9.291 #2941 SMP Thu Dec 2 04:53:08 +07 2021 armv7l
Previous: DD-WRT v3.0-r47581 std (10/20/21)
Reset: YES: erase nvram and manually configured
Uptime: ~ 2 Days
Status: Solid release so far, seems like wifi signal rates have slightly improved
Issues/Errors: None so far
AP/Router with mix of Windows, Android and Apple. DNSMasq with DNSCrypt, Firewall enabled, extra IP rules, static leases, dnsmasq forwrding of bad domains, wifi WPA2 with AES, mac filtering

12/08 update: I made some tweaks:
1. cts/rts threshold to 2346 (same as I had it in 44048)
2. beacon / dtim to 300 / 1 (same as I had for 44048)

12/08 Update:
Connections are stable (great!) and overall it is a great build.
However, BTW I AM NOT TRYING TO DISPROVE ANYTHING HERE, JUST BEING TRUTHFUL: wifi speeds are still not like 44048. I can live with as a trade off for dnsmasq dnspooq fixes. e.g. using devices I always use for benchmarking, I always got 90%+ of my ISP's CAP on 44048. on 47720: I get 70-75% of the CAP

Anyay, I know Marvel hw is crap and I'll probably look for a R7800 or XR500 pre-owned with ddwrt. It is just hard to find one and I do not wish to speed a ton when this router is functional

Why are you using client mode threshold for AP? RTS/CTS protection and threshold are irrelevant for AP modes.
