I wonder if this has anything to do with the law suit by Netgear and now Asus has lowered the radio power to comply with Fcc law. This is somthing i feared might happen. Ofcourse nobody can be sure.
I don't think so.
1) Here in Germany the device had already a strict limit for radio power in prior versions.
2) Compared with 33-beta1 the tx power of version 374.720 is equal to 5-10 mW. Or with other words the signal strength of my neighbours router is at the same or even higher level than from my own router just 3 meters away.
