It is possible to put a wireless network card on ur laptop givin that the laptop supports it. wirelessly connect to ur laptopto ur car audio? yes, ive heard of this before but not much on it. but yes you can do it.
I am having a problem adding a wireless LapTop to a wired network. The LapTop accesses the Internet without any problem, but I cannot add the LapTop to the network. The LapTop is showing in the correct workgroup but it will not allow access from any of the other computers. I receive the message '//computer is not accessible. You may not have permission to use this network resource'.
