Asus RT-N13U Rev.B1
If you’re on a tight budget but still want a feature-rich router, then nothing beats the RT-N13U from Asus. The new revision B1 model comes with double the memory and RAM, so one can install bigger custom firmware packages. The router has a built-in antenna. Yet, it has a very good range, and supports a single USB 2.0 port and a WPS button to quickly pair with any device. The router also supports printer server and DD-WRT for adding more functions like Torrent downloading, NAS and SAMBA features.
