Chapter 3 NOTE: The settings on the Advanced Wireless Settings screen are designed for advanced users only. Advanced Wireless Use LDPC Low-Density Parity-Check Code (LDPC) enables or disables error correction to reduce the probability of data loss in noisy channels. The Rate Adaptation algorithm automatically disabled LDPC coding when working at high PHY rates (higher than 162). To use the LDCP advanced error correction scheme, keep the default, Yes. Otherwise, select No. ERP Protection Type This option configures protection of OFDM packets despite the presence of 802.11b stations within the wireless network. By sending RTS/CTS or CTS2Self packets in 802.11b rates, the Bridge informs the wireless network that OFDM packets are going to be transferred and protects the packets in the wireless network. The RTS/CTS and CTS2Self packets create overhead, which may result in lower throughputs. The RTS/CTS option provides better coverage but lower throughputs when compared to CTS2Self, because the RTS/CTS option includes acknowledgement from the receiving device. To use the RTS/CTS option, keep the default, RTS/CTS. The None option may cause collisions between OFDM and CCK packets. To use the None option, select None. To use the CTS2Self option, select CTS2Self. 11n Protection Type This option configures protection from non-High Throughput (HT) devices within the wireless network. In case the wireless router (or access point) detects an association of a non-HT legacy device, it will signal all the HT devices to use RTS/CTS or CTS2Self mechanisms before each data transmission. This feature also supports all 802.11n standard protections, including MIMO. The RTS/CTS option provides better coverage but lower throughputs when compared to CTS2Self, because the RTS/CTS option includes acknowledgement from the receiving device. To use the RTS/CTS option, keep the default, RTS/CTS. The None option may cause collisions between HT and legacy packets. To use the None option, select None. To use the CTS2Self option, select CTS2Self. Percentage of maximal transmit power This option sets the percentage of maximal transmit power relative to the regulatory domain restrictions. For example, if the regulatory domain restriction allows transmissions of up to 20 dB, then setting the percentage at 50% allows maximal transmit power of 10 dB. Select the percentage you want to use: 12%, 25%, 50%, or 100%. The default is 100%. QoS Classification Type This option sets 802.1D or 802.1Q mapping from the IP DSCP/TOS field to WMM priorities (Background, Best Effects, Video, Voice). Keep Wireless-N Ethernet Bridge with Dual-Band Advanced Configuration the default, 802.1D, or select 802.1Q, which is used by some IPTV streams. Click Save Settings to apply your changes, or click Cancel Changes to cancel your changes. Network Setup > Basic Network Settings Change the Bridge's wired, Ethernet network settings. Network Setup > Basic Network Settings (Automatic Configuration DHCP) Network Setup > Basic Network Settings (Static IP) Basic Network Settings This section determines if the Bridge's IP address is obtained automatically from a DHCP server, such as your network router (Automatic Configuration - DHCP), or set manually (Static IP). Network Connection Type If your network has a DHCP server, such as your network router, assigning IP addresses to your network devices, then keep the default, Automatic Configuration - DHCP. The Bridge will request an IP address from the DHCP server (usually the network router). If no DHCP server is found, then the Bridge will use its default static IP address, 169.254.1.250, until it detects a DHCP server and is assigned a dynamic IP address. If you want to set a permanent static IP address for the Bridge, then select Static IP. If you select Static IP, then complete the following fields: •• Static IP Address Enter a unique IP address that will be used to access the web-based utility. •• Subnet Mask Enter the subnet mask of your wired network. 9
