There are multiple types of DWL900AP boxes. The one's without the + at the end have insipid radios and buggy firmware. The DWL-900AP+ comes in the rev A1, B1, E1, and probably some others. The A1 and B1 are ok, but the E1 and up are nice because they can be upgraded to
802.11g. The packaging is also different between the non-+ and the + versions.Be sure to thank D-Link marketing for their heroic efforts to minimize product differentiation and maximum customer confusion.
Well, I have a DWL-900AP+ rev B1 connected in client mode from the neighbors house to my BEFW11S4 at this very moment.
Firmware version? Update? As I vaguely recall (not sure), the original DWL-900AP (no plus) didn't work at all in the client or repeater modes.
This is for the DWL-900AP+ and does NOT apply to the DWL-900 (no plus).
Incidentally, I have about 4 or 5 point to point 22mbit/sec links that use DWL-900AP+ radios (mostly rev A1 and B1) and that have been up for years with few problems.
