1. Introduction
ERB9250 is a 2.4GHz 802.11b/g/n Range Extender. You can extend the reach of your
wireless network to areas with poor signal reception or dead spots by adding an ERB9250 for
greater coverage.
The Range Extender works as a bridge to connect and extend your existing wireless network.
It receives the signal from a wireless router and rebroadcasts the signal outside of the router’s
wireless coverage area. The ERB9250 can only re-boost strong or good signals received from a
wireless router. Thus, placing the ERB9250 in a location where a good signal (at least 3 bars) is
still available and which is in clear line of sight with your router (as few obstructions as possible)
will ensure that your wireless coverage can be expanded, minimizing areas prone to weak or no
signal coverage.
While the ERB9250 Range Extender can benefit users when they are in a weak spot or dead
zone in the existing wireless network, the best performance will be obtained by connecting to the
original wireless network when possible. Because the Range Extender relays the wireless signal,
it is inherently slower than traffic which is on the original wireless network. Consequently,
EnGenius recommends that users connect to the Range Extender only when they are not able to
receive good signal strength from the original wireless network.
The ERB9250 Range Extender supports WEP, WPA, and WPA2 encryption standards to
ensure compatibility with a majority of routers. To ensure optimum performance, it is highly
recommended to utilize an EnGenius 802.11b/g/n router to pair with the ERB9250. The following
EnGenius routers have been tested to operate better with the ERB9250: ESR9752, ESR9753,
ESR9850, ESR9855G, ESR1221N, and ESR1221N2.
