Thanks Joe... Wow, I have reminded myself not to post replies late at night when my brain isn't operating at 100%. WiMax included with some of the DV7 models from HP, mostly ones sold through Best Buy offered WiMax service. Best Buy offered mobile broadband service for a very short time, then migrated their customer over to Clear Mobile Broadband.
WiDi had nothing to do with the original question, so my sincere apologies. And Thanks again Joe. I meant to log back on the next morning to clarify this myself, but am glad you reminded me to retract my comment.
Either way, Intel does have new drivers for WiMax, or you can ignore it if you do not subscribe to a mobile broadband service that work with your WiMax service.
