yet he will have to get a wireless router who's range will be limited ... and will cost 6k
besides there will just be multiple P@P connections formed for each pair of wireless device ...
a switch for 14 pc's would be a good idea
afaik neither of the options will make a much of a diff
using 2 switches however for the ip's on the secong switch the first switch will have to broadcast on all ports of the second switch
forwarding thru 2 mac addresses will take place ..
rather jsut get one if u can have a central place to keep it n connect all pc's
