回复：a question about networking

1、需要宽带ADSL 或CABLE Modem
2、买一4口无线ROUTER，有的带PRINTER Server，如USRobotics MAXg 5461.有一USB口接打印机，只要有USB口的打印机就可以。
3、4Port Wireless Router Support 4 Wire Cable Connection。 Usually up to 100 Mbps. Meanwhile, it will support 250+ wireless connection( the total is 254). Wireless connection support up to 54M(802.11g) or 11Mbps (802.11b standard). Wireless is OK, since you broadband connection is much less than the wireless connection.
4. If the wireless router don't have printer server function, you can buy a printer server or you can use a computer to share the printer. The computer have to be on for all other computers to print.
