So the radio stuff was OK in 3.3 Ghz - BUT I have never managed to perform a complete EAP association: each time the card was supposed to present its keying material to the EAP server, it just broke up the eap conversation. I was wondering if the allowed certificates are hard-coded inside the WiMAX 6250 card firmware ? I have never had any answer on that so far. Hope it helps PS: Keep us informed if you make it work !
