Because the Engenius ESR-1221EXT High-Power Soho Router device has an external antenna port, you could use the high gain external antenna kits above to boost your signal. However, if your access point is very far, or you need to reach a WLAN station that is very far, or you require a very long cable run to get from the antenna mounting location to the device (long runs lead to large signal loss) consider using other Wi-Fi signal extension solutions as indicated below.
