I am thinking seriously about a Slacker radio, but I am worried that I will have a difficult time getting it set up and loaded. I have no wireless internet subscription or provider, so I'll have to use my USB port. I'm worried my Windows Defender firewall will be stubborn. I'm worried that the IP address Slacker uses will be rejected by my computer as already in use, and that I'll have a hard time getting around this. Are these legitimate worries? Or should I not worry?
