ERB9250 Wireless N300 Range Extender

The EnGenius ERB9250 is a 2.4GHz Wireless N300 Range Extender with one Fast Ethernet port. In Client Bridge mode, it can be used to connect an Ethernet-enabled entertainment device like a Blu-ray player, set top box, DVR or game console wirelessly to an existing home router in another part of the house or repeat a home router’s signal to eliminate dead zones and extend a home network.

In Repeater (Range Extender) Mode
The ERB9250 receives the signal from a wireless router and rebroadcasts it beyond the router’s wireless coverage area. It features greater signal coverage than ordinary wireless repeaters and extends the reach of an existing wireless network connecting to computers and other 802.11b/g/n devices in areas that previously experienced poor signal reception or even no signal at all.

The ERB9250 is easy to connect to your existing network by using the WPS buttons on both the ERB9250 and your existing router or by configuring it using the easy browser-based configuration Graphical User Interface (GUI).

The ERB9250 supports WPA, and WPA2 encryption standards to ensure compatibility with a majority of routers.

**The updated firmware rev 2.0.2 is also available in the tab of Resources for easier installation for ERB9250.**

Wireless N300 Speed
Up to 300 Mbps wireless speed. Complies with the IEEE 802.11n standard and is backward compatible to 802.11b/g devices.
Extends the Reach of Your Existing Home Router
Relays the signal of your existing wireless home router to create a larger coverage area for more device connectivity.

Helps to eliminate wireless dead zones in your home due to construction materials or other architectural or environmental factors.
WPS - Push Button Setup
Easy to connect to your existing network by using the WPS buttons on both the ERB9250 and your existing router.
