Wireless-B Broadband Router
RTS Threshold. Should you encounter inconsistent data flow, only minor reduction of the default value, 2346, is recommended. If a network packet is smaller than the preset RTS threshold size, the RTS/CTS mechanism will not be enabled. The Router sends Request to Send (RTS) frames to a particular receiving station and negotiates the sending of a data frame. After receiving an RTS, the wireless station responds with a Clear to Send (CTS) frame to acknowledge the right to begin transmission. The RTS Threshold value should remain at its default value of 2346.

Filters block specific internal users from accessing the Internet. From the Filters tab, you can set up a filter through an IP address or a network port number.

Users who have filtered IP addresses will not be able to access the Internet at all. If you only want to filter one IP address instead of a range of IP addresses, enter the same value into both fields. For instance, if you wish to filter the PC with the IP address of 192.168.1.5, enter 5 into both fields on one line: 192.168.1.5 ~ 192.168.1.5.
Filter Port Range. To filter users by network port number, select a protocol, then enter a network port number or a range of network ports. Enter the port numbers you want to filter in the port numbers fields. Users connected to the Router will no longer be able to access any port number listed there.
Filter MAC Address. This feature filters the Ethernet adapter’s specific MAC address from going out to the Internet. To check your Ethernet adapter’s MAC address, you can run winipcfg or ipconfig in the command prompt, depending on which Windows operating system you are using. To set the MAC filter, click the Edit MAC Filter Setting button. When the screen appears, select the range in the
