I'm trying to setup wifi connections to be 2 hours after a purchase is made. My POS runs on mysql tables...I can have users enter their ticket number and total amount for verification. If ticket has not been tagged and verification checks out, then login for web access. What minimum packages would I have to install to make this happen? Any suggestions? (running a 4mb or 8mb flash capacity router). Also, how can I manually disconnect an authenticated client? Thanks much
