This is the first time I've heard of such a difference in range. I don't
know whether the firmware would be doing something differently as far as
radio configuration is concerned between client and Host AP mode. Which
firmware version are you using? Are you setting any wireless parameters
with iwconfig/iwpriv? Do you have a wireless sniffer that would report
signal strength on the received frames? It could be useful to compare
the signal strength of the frames send by the device that is using Host
AP driver when in Host AP and client modes.
