i want to know which sharing is best router or windows sharing manully i want to share my internet to 16 compter which is good for me and worked fast and smooth and should i keep static ip on workstation or dynamic which worked fast without problme

With 16 computers you need a router. I wouldn't contemplate for one moment sharing an Internet connection through Windows with that many computers. You need a router which normally comes with 4 Ethernet ports then a 16 port switch to expand the network to the 16 computers. I would use dynamic IP addresses through DHCP. It will save you the administrative burden of manually allocating IP addresses. Stuart
