I downgraded from Vista Business to XP Pro on my TZ150n. I obviously have the integrated WAN. I downloaded the EVDO drivers and installed them, my WAN is enabled, but I don’t have any way that I know of how actually to use the WAN. The connection manager software that Sony provides only works in Vista. I tried installing it anyways, it wouldn’t install. I contacted the card manufacturer, EVDO or something, spoke with a tech guy, and he said he did the same thing as I on his TZ150, and that the connection manager software to actually use the card comes from Sony. Sony won’t actually tell me whether they make the software for XP; they just keep telling me that this computer will only work with Vista. Will Sprint mobile broadband software for XP help in resolving my issue? How can I get it? Please help. Thanks.
