The ASUS wireless router distinguishes itself with the "auto switching" function. It not only enables multiple users to use multifunction printer wirelessly without a PC or server turned on 24 hours a day, but also rules out the trouble of repeating "disconnecting" & "re-connecting" when users switch. When different users are to use the printer, the router switches automatically, which enables different users to use the printer simultaneously. After plugging in the USB (Universal Serial Bus) printer into ASUS wireless router & running the ASUS Network Printer Setup program, each user can enjoy easy scanning & easy printing. The ASUS EZ Switch provides three operation modes, user can change it more easily, only one-touch. Ai Disk combines simple FTP settings with the ASUS DDNS service to share files with friends easily no matter when & where the user is. By simply utilizing the RT-N13U with a USB (Universal Serial Bus) hard disk, users will be able to create a mini FTP server at home & only requires them to setup an account & password & select the file they want to share. Users will be able to easily create their own FTP servers with easily recognized & meaningful hostname, instead of a hard to remember IP addresses or URLs. HTTP, FTP, BT (Bit Torrent) download protocols can be download automatically from the Internet. You can keep downloading even when PC is off. After buying router & preparing for setup, just connect to the router & QIS will automatically guide users to their browsers default home pages.
