Hello and I hope that you are well. I have been quite happy running DavidC502's Build's on the WRT3200ACM and WRT32X for years now and I am an active member of his Community Forum found here: : Davidc502- wrt1200ac wrt1900acx wrt3200acm wrt32x builds and his website : https://dc502wrt.org/ -
Dave's Community Thread in addition is frequented by OpenWRT experts and mavens plus there is great advice and support on the Community Thread and you can even request new packages and features.
As far as resetting the WRT3200ACM or any of the Routers which Dave supports listed here:
Current images built and distributed.
WRT1200ac Version 1 and 2
WRT1900ac Version 1 and 2
WRT1900acs Version 1 and 2
WRT3200acm Version 1
WRT32X Version 1
See this page to reset your router to default settings and clear ram : https://www.routerdefaults.org/linksys/wrt3200acm - doing a 30-30--30 reset potentially has you running the risk of bricking your router. Follow these steps in order:
Press the reset ( hold it down ) for 20 seconds - watch the lights flash - wait for unit to reboot fully - next unplug the router - wait 30 seconds. Then plug the router in once again - let it boot up. Then you are done. Hope this helps.
Peace and God Bless
