I was purchased a TP-LINK WIFI router ( model TL-WR841N 300mbps) last year. The range of this router is very good approximately 20m. It has stylish body and look. It is combined wired/wireless network connection device.
It has two antennas greatly increase the wireless robustness and stability. And its has easy wireless security encryption at a push of WPS button.
The cost of this router is economical.
