This seems to affect WAN more than LAN, but LAN is still slower than what it should be.

I have a 100mega-bit download that is pretty consistent when I test on a wired connection

When I test on a wireless connection 5Ghz, it is consistently at 30mb/s

When I test a file transfer to my nas, the wireless can do a 90mb/s file transfer, still lower than the 200/400mb/s tx/rx speed that the dd-wrt landing page says my device is connected at (phone and desktop)

I have tried manually setting the wireless channels, manually setting the tx power from 71 to 80, and lowered it to 50... all didn't change anything.

Tried AC only and mixed mode

Tried wide channel, no affect

Tried enabling/disabling the beamforming options

I have been testing with the AP in the same room

I never would have noticed til my brother came over and immediately was like WHY IS THE WIFI SO SLOW, now it's bothering me to the point where I just might wind up disabling the wifi on the router and buying a ubiquity AP or something along those lines

edit file attachments were working... oops


edit 2

I changed the router to Merlin Firmware, WAN over 5ghz wifi reaches 100mb/s... it's been a pleasure, DD-WRT, but I guess here is where we part ways.
