hi, i'm looking to upgrade my 3 wap54g's (1ap, 1 bridge, and 1 repeater) to the new wap54gx's. has anyone actually gotten and installed one of these yet? if so, i have a few questions about them. 1. do they support the linksys hga7t antennae? if not, is there something else that is equivalent? 2. is the range & speed actually significantly better than the wap54g (i use wpa, g band only, and have speedbooster turned on)?
