Thank,
you know where i can find one list of devices (usb dongle) with more
ram, or without this limit (I need provide Internet at less to 30
stations)?
Another question, how I can find this limit in others dongles? (some
command to know this limit)

Thanks Thomas, but is not an option using a "real" AP... I realy need
to make my own (I need access to MAC address of connected devices and
use the monitor mode at the same time).
You have some link to steps to "upgrade/install" the modify version of
frimware in my device (TL-WN722N) ?
This is one or two step ahead of my confort zone :)

The device I mentioned earlier is fully supported by openwrt, which
gives you a standard linux environment on your router.

No. But a "real" AP would be cheaper and much more perfomant anyway.
Something like the TP-LINK WR841n can be had for about $20.
Nothing stopping you from setting HTC_MAX_STA to 30 and seeing what
happens either!
