You've just diagnosed the problem. It has nothing to do with the
wireless, and has to do with the kernel parameters for maximum TCP and
UDP ports (really, NAT settings) or TCP/UDP timeout.

On DD-WRT v24, this is set on the Administration tab, Management subtab,
bottom of page, "IP Filter Settings (adjust these for P2P". Exactly what
to use depends on your hardware (RAM, really) and firmware.
