Network Name(SSID): When you are browsing for available wireless networks, this is the name that will appear in the list (unless you set it to Hidden, see below). This name is also referred to as the SSID. For security purposes, it is highly recommended to change from the pre-configured network name. Default is 3Jtech WiFi. Hidden: The option allows you to hide your wireless network. When this option is unchecked, your wireless network name is broadcast to anyone within the range of your signal. If you're not using encryption then they could connect to your network. When you click on this checkbox to enable this function, you must enter the Wireless Network Name (SSID) on the client manually to connect to the network. Multiple SSID 1 ~ 3: Up to three SSIDs you can additionally set up for this wireless network.
Super Modem IIIUser’s Manual 20 Broadcast Network Name (SSID): Enable/Disable the SSID broadcast function. This function is used to control the broadcast status of all SSIDs. If this function is disabled, all SSIDs you had set up for the router will be hidden. To cancel the hidden status for the specific SSID, you can uncheck the “Hidden” option in the back of your desired SSID. AP Isolation: Enable/Disable this function. Create a separate virtual network for your wireless network. When this feature is enabled, each of your wireless clients will be in its own virtual network and will not be able to communicate with each other. You may want to utilize this feature if you have many guests that frequent your wireless network. MBSSID AP Isolation: Enable/Disable the MBSSID AP Isolation function. The router supports multiple SSIDs. You can decide whether the clients associated to different SSIDs on the device can see each other or not. Enable the option to block it. Default is “Disable”. Frequency (Channel): A wireless network uses specific channels in the 2.4GHz wireless spectrum to handle communication between clients. Some channels in your area may have interference from other electronic devices. Choose the clearest channel to help optimize the performance and coverage of your wireless network. If you select AutoSelect, the router automatically finds the channel with least interference and uses that channel for wireless networking. Rate: Exist only when selecting 802.11b/g mixed mode, 802.11b only, 802.11g only as the Network Mode for the router. You can set up the desired transmitting rate for these network modes. Default is Auto. HT Physical Mode Settings: This mode settings exist only when 802.11b/g/n mixed mode or 802.11n only(2.4G) is chosen as your router’s Network Mode. Operating Mode: Select the option to enable the Mixed Mode or the Green Field Mode for physical layer transceivers. Default: Mixed Mode. Mixed mode: In this mode the device transmits the packets with preamble compatible legacy (802.11g), so they can be decoded by legacy devices. The device receives and decodes both Mixed Mode packets and legacy packets. Green Field mode: The device transmits HT packets without legacy compatible part. But the device receives and decodes both Green Field and legacy packets.
Super Modem IIIUser’s Manual 21 Channel BandWidth: This option only works when selecting Network mode in 11b/g/n mixed mode and 11n mode. Select the option to choose 20 MHz or 20/40MHz. This option affects the Phy data rate of radio. Please refer to the table below, which shows the relationship among Phy data rate, Bandwidth and Guard Interval. Guard Interval: The 11n device inserts the Guard Interval into the signal. You can choose the interval between ”Long” and “Auto”. This option affects the Phy data rate of radio. For more details, please refer to the table below. MCS: It means “Modulation Coding Scheme”. The available options are “Auto, 0, 1, …15, and 32”. It changes the modulation of this device and effect the maximum Phy data rate. We recommend “Auto” setting. For more details, please refer to the table below.
Super Modem IIIUser’s Manual 22 Reverse Direction Grant(RDG): This is the 11n performance parameter. Enable it if needed. Extension Channel: Exist only when selecting “20/40” as the Channel BandWidth for the router. For example, if channel 6 is selected, it means you can select channel 2 or channel 10 as the extension channel. Choose the unused channel as the extension channel. Aggregation MSDU(A-MSDU): The multiple HT packets can be transmitted with single ACK reply packet. Enable it to apply this function and reduce the network congestion. Auto Block ACK: It is another aggregation technique which prevents sending ACK in the communication to increase the throughput. If this option is enabled, the device will activate this function when transmitting massive data. Decline BA Request: Enable this option to decline the Block ACK request addressed by the other devices.
Super Modem IIIUser’s Manual 23 3.2.2 Wireless Security/Encryption Settings In this section, you can configure the wireless security and encryption to prevent from unauthorized access and monitoring. Please choose a SSID you had created for this router in the Wireless Settings Æ Basic setting page from the SSID Choice pull-down list. There are 4 encryption modes, including Disable, WEPAUTO(WEP), WPA-PSK and WPA2-PSK offered for your selection. Please also pull down the Security Mode list and select the desired mode for your router’s wireless security. For more details about the setup in these different modes, please refer to the following sections. 3.2.2.1 Disable Mode In this mode, wireless clients can directly connect to the router without inputting any key.
Super Modem IIIUser’s Manual 24 3.2.2.2 WEPAUTO(WEP) Mode WEP is a method of encrypting data for wireless communication intended to provide the same level of privacy as a wired network. WEP is not as secure as WPA encryption. To gain access to a WEP network, you must know the key. The key is a string of characters that you create. When using WEP, you must determine the level of encryption. The type of encryption determines the key length. 128-bit encryption requires a longer key than 64-bit encryption. Keys are defined by entering in a string in HEX (hexadecimal - using characters 0-9, A-F(a-f)) or ASCII (American Standard Code for Information Interchange - alphanumeric characters) format. ASCII format is provided so you can enter a string that is easier to remember. The ASCII string is converted to HEX for use over the network. Example, 64-bit hexadecimal keys are exactly 10 characters in length. (12345678FA is a valid string of 10 characters for 64-bit encryption.) 128-bit hexadecimal keys are exactly 26 characters in length. (456FBCDF123400122225271730 is a valid string of 26 characters for 128-bit encryption.) 64-bit ASCII keys are up to 5 characters in length (DMODE is a valid string of 5 characters for 64-bit encryption.) 128-bit ASCII keys are up to 13 characters in length (2002HALOSWIN1 is a valid string of 13 characters for 128-bit encryption.)
Super Modem IIIUser’s Manual 25 WEP Keys: Select “ASCII” or “Hex” from the pull-down list to set up the key value. ASCII (American Standard Code for Information Interchange) is a code for representing char as numbers from 0-127. Hexadecimal digits consist of the numbers 0-9 and the letters A-F (a-f).
Super Modem IIIUser’s Manual 26 3.2.2.3 WPA-PSK / WPA2-PSK Mode WPA (Wi-Fi Protected Access) is the older standard; select this option if the clients that will be used with the router only support the older standard. WPA2 is the newer implementation of the stronger IEEE 802.11i security standard. PSK(Pre-Shared Key) is the key which is entered as a pass-phrase of up to 63 alphanumeric characters in ASCII (American Standard Code for Information Interchange) format or 64 digits in HEX format at both ends of the wireless connection. When inputting ASCII strings, it cannot be shorter than eight characters, although for proper security it needs to be of ample length and should not be a commonly known phrase. This phrase is used to generate session keys that are unique for each wireless client. WPA Algorithms: Mark the option to enable modes of TKIP or AES. Pass Phrase: This mode requires only an access point and client station that supports WPA-PSK. The WPA-PSK settings include Key Format, Length and Value. They must be as same as each wireless client in your wireless network. When Key format is Passphrase, the key value should have 8-63 ASCII characters or 64 digits in HEX format.
Super Modem IIIUser’s Manual 27 Key Renewal Interval: Enter a value to set up the WPA key renewal interval. The device regenerates the key in every interval seconds that you have setup without disconnection. The WPA Algorithm will regroup the key for a period. The default value is 3600 seconds, and you can adjust the time interval (Valid Range: 0 ~ 4194303).
Super Modem IIIUser’s Manual 28 3.2.3 AP Client Settings With the AP Client function, the Super Modem III could connect to other remote WiFi AP(AP1) as a WiFi station, and it will be bridged with Super Modem III WiFi AP and LAN, which means that PC WiFi clients under AP1 and PCs clients under Super Modem III LAN and WiFi could communicate with each other. Just fill in the network name (SSID) and the pass phrase (security key) of the WiFi AP that Super Modem III would like to connect. Please note that the setup of Network Mode as well as Frequency Channel No. for the Super Modem III in the Wireless Settings Æ Basic setting page must match the values used on this WiFi AP.
