1. Introduction ERB9250 is a 2.4GHz 802.11b/g/n 300Mbps Repeater & Client Bridge (Range Booster / Extender). Range Extender solves the signal attenuation (limited coverage) problem by literally repeating / extending AP radio signal to dead-spots. While repeater clones AP and serves as a subsidiary entity to its clients, client bride offers an extension of wired network to the AP.
1.2.
1.3. System Requirements To begin using the ERB9250, make sure you meet the following as minimum requirements: Existing AP / Router PC/Notebook. Operating System – Microsoft Windows 98SE/ME/XP/2000/VISTA 1 Free Ethernet port. WiFi card/USB dongle (802.11b/g/n) – optional. External xDSL (ADSL) or Cable modem with an Ethernet port (RJ-45). PC with a Web-Browser (Internet Explorer, Safari, Firefox, Opera etc.) Few Ethernet compatible CAT5 cables.
2. Installation Please configure your PC / Notebook Ethernet card IP address before device configuration. 2.1. PC Network Adapter setup (Windows XP) • Enter [Start Menu] select [Control panel] select [Network].
• Select [Internet Protocol (TCP/IP)] =>Click [Properties]. • Select the [General] tab. • ERB9250 supports [DHCP] function, please select both [Obtain an IP address automatically] and [Obtain DNS server address automatically].
2.2. Bring up ERB9250 Connect the supplied power-adapter to the power inlet port and connect it to a wall outlet. Then, ERB9250 automatically enters the self-test phase. Once WLAN LED is on and blinking randomly to indicate that it is in normal operation.
3. Quick Setup Range Extender Prerequisite: Before we start, please make sure the extender is within the coverage of your existing AP. We suggest you place your extender right next to your AP for the initial setup. We can move the extender to further location after configuration is completed. ERB9250 default IP address is 192.168.1.2, please ensure it is not occupied by any other devices. Power On: Connect the supplied power-adapter to the power inlet port and connect it to a wall outlet.
4. Once the orange WLAN LED stop blinking and staying on, the setup is then completed. If the LED does not stay on, this means the configuration is not successful. In case you do not have the extender right next to your AP, please move your extender closer and make sure the antennas are properly screwed firmly on the devices. Repeat steps 1~4 again. If the configuration fails again, this probably means your AP does not support one-touch setup function. Please configure your extender manually.
8. Click on [Site Survey] to search the existing AP. 9. Few seconds later, a window will pop up a list of available APs. 10. Select your target AP and click on [Connect]. 11. Enter the access key for the target AP and click on [Save]. 12. Pop-up box showing the connection established between AP and the extender. 13. On the extender status page, you should see AP security information being cloned here.
4. ERB9250 Placement 4.1. Placement Please note that there may be various interferences and obstacles in the environment that can impact wireless network performance. Most of the wireless driver utility provides signal strength visualization. You can make use of it to measure the signal strength of your AP. You may need to experiment a few times to find out the best location for the range extender. Generally, placing extender at where the AP signal strength greater than 30% considered suitable.
between the two nails is 89mm. Finally, carefully mount the device onto the wall and make sure the nails are firmly locked on the mount points.
5. Smart Wizard Please insert the Wizard CD into your CD-ROM driver. If you are using MacOS or other operation system, please browse your CD and click on index.html to start Smart Wizard.

6. Initial Setup ERB9250 ERB9250 uses web-interface for configuration to be accessed through your web browser, such as Internet Explorer or Firefox. 1. OPEN your browser (e.g. Internet Explorer). Type http://192.168.1.2 in address bar and hit [Enter] button on your keyboard. Click to navigate into ERB9250 configuration home page. You will see the home page of ERB9250 as follows.
7. System 7.1. Operation Mode This page allows you to change device operation mode. ERB9250 supports Universal Repeater (Range Extender) and Client Bridge mode. By default it is configured as an Universal Repeater (also known as Extender). If you are not sure what Client Bridge is, please do not use this mode. Client Bridge is not an AP extender but an “Ethernet Wireless Extender”. CB serves as a bridge between wired network and wireless network.
7.3. Event Log View operation event log. This page shows the current system log of the Broadband router. It displays any event occurred after system start up. At the bottom of the page, the system log can be saved to a local file for further processing or the system log can be cleared or it can be refreshed to get the most updated information. When the system is powered down, the system log will be cleared if not saved to a local file.
7.4. Monitor Show histogram for network connection on WAN, LAN & WLAN. Auto refresh keeps information updated frequently. 7.5. DHCP (CR Mode) View the current LAN clients which are assigned with an IP Address by the DHCPserver.
network. The table shows the assigned IP address, MAC address and expiration time for each DHCP leased client. Use the button to update the available information. Hit to get the updated table. You can check “Enable Static DHCP IP“. It is possible to add more static DHCP IPs. They are listed in the table “Current Static DHCP Table“. IP address can be deleted at will from the table. Click button to save the changed configuration. 7.6.
Edit schedule options to allow configuration of firewall and power savings services. Fill in the schedule and select type of service. Click to keep the settings.
8. Wireless 8.1. Status 8.2. Basic Radio: You can turn on/off wireless radio. If wireless Radio is off, you cannot associate with AP through wireless. Mode: In this device, we support three operation modes which are AP router and AP route with WDS. If you choose AP Router Mode, you can select AP or WDS function in the drop-down menu.
Band: You can select the wireless standards running on your network environment. 2.4 GHz(B): If all your clients are 802.11b, select this one. 2.4 GHz(N): If all your clients are 802.11n, select this one. 2.4 GHz(B+G): Either 802.11b or 802.11g wireless devices are in your environment. 2.4 GHz(G): If all your clients are 802.11g, select this one. 2.4 GHz(B+G+N): Either 802.11b, 802.11g, or 802.11n wireless devices are in your environment.
8.3. Advanced Fragment Threshold: This specifies the maximum size of a packet during the fragmentation of data to be transmitted. If you set this value too low, it will result in bad performance. RTS Threshold: When the packet size is smaller than the RTS threshold, the wireless router will not use the RTS/CTS mechanism to send this packet. Beacon Interval: This is the interval of time that this wireless router broadcasts a beacon. A Beacon is used to synchronize the wireless network.
N Data Rate: The “Data Rate” is the rate that this access point uses to transmit data packets for N compliant wireless nodes. Highest to lowest data rate can be fixed. Channel Bandwidth: This is the range of frequencies that will be used. Preamble Type: The “Long Preamble” can provide better wireless LAN compatibility while the “Short Preamble” can provide better wireless LAN performance. CTS Protection: It is recommended to enable the protection mechanism.
ESSID Selection: This broadband router support multiple ESSID, you could select and set up the wanted ESSID. Broadcast ESSID: If you enabled “Broadcast ESSID”, every wireless station located within the coverage of this AP can discover this AP easily. If you are building a public wireless network, enabling this feature is recommended. Disabling “Broadcast ESSID” can provide better security.
Key Length: You can select the WEP key length for encryption, 64-bit or 128-bit. The larger the key will be the higher level of security is used, but the throughput will be lower. Key Type: You may select ASCII Characters (alphanumeric format) or Hexadecimal Digits (in the "A-F", "a-f" and "0-9" range) to be the WEP Key. Default Key: It’s the key used to encrypt data. Key1 - Key4: The WEP keys are used to encrypt data transmitted in the wireless network.
frequently. So the encryption key is not easy to be cracked by hackers. This is the best security available. 8.5.
