Hi have brought a bsquare maui on ebay great machine and the screen is fantastic clarity, i have seen different posts about the device on this forum, but i need some more help, i have been trying to get wifi or wireless lan working using a wifi card and i have seen some comments about sdio now, i have tried a sandisk wifi+256mb sido card and it didnt seem to work i could see it as a storage card but no wifi, i have tested it on another compaq and the wifi worked a treat., i have tried different drivers, most of the time they dont work or that device says files are missing or already loaded into rom?????. does anybody know what wireless card works in the b square and what drivers work with it too please help . its driving me crazy. seems the machine eats the drivers and there not there odd!!!!!
