Thanks Martin. Can the CISCO 877 Router (with build-in ADSL modem) act as firewall also? It has 4 ports but only one is used now. The router's password is controlled by M1 because we have no System Administrator. From your suggestion, I shall buy another wifi router+switch connects to one port of CISCO 877 and then connect a 24-port switch to the wifi router+switch and do the same for staff sub-net. In this case the 2 sub-nets are isolated by the wifi router+switch and the result is the PCs in student/public sub-net cannot access server and PCs in staff sub-net and vice versa. Is my understanding correct? Shall I worry about the speed accessing Internet will be slower due to one additional router being added as I notice the wifi speed is always much slower than the fixed line connection (I use http://www.bandwidthplace.com/ to test speed and the wireless speed is normally 50% slower). What is the normal delay expected when one additional router is added? The wifi router+switch we are using now is Linksys WRT310N. Any suggestion of better make and model?
