I have a similar problem in 3.9 with ral cards; very poor range. Linksys (ath) [ap] - Level One (ral) = 5-7 meters Linksys (ath) [ap] - Old 1MBit Intel (wi?) = +30 meters Level One (ral pci) [ap] - Level One (ral pccard) = must be within 1-2 meters I tried changing the Tx Power, but that didn't have an effect. Because I've heard that the ral driver is very good, I was just assuming that my Level One cards have crappy transceivers and/or antennas.
