Our shop has had trouble using the prism based cards with a lucent access point, allegedly due to encryption incompatibilities. However, the prism access point/lucent client scenario is much more promising... We are phasing out the lucent APs as quickly as possible after a number of our units were reconfigured by a SNMP explit regardless of ACLs in place, and the only response from orinoco was 'reflash your firmware', depsite our using the newest version already. Ultimate solution was to employ SNMP blocking very aggressively on our routers and to arbitrarily change the IP of the AP itself on a regular basis. Not really the way you want to have to operate when dozens of corporate contracts ride on these APs. With that, great thanks to all those who work on the HostAP project! I look forward to contributing in any way possible.
