Ok to answer part of my own question The DWL-520+ is 2.4ghz and fully
802.11b compliant. But it uses a texas instruments chip that gives it
faster speeds when connecting to other D-Link airplus gear. 

<snip>When connected to other D-Link AirPlus products, the performance
is even greater — up to 22Mbps!</snip>

so it is at least supposed to be compatible
