Linksys NWR04B manual Network Everywhere Series

Network Everywhere® Series

•RTS Threshold. This value should remain at its default setting of 2,346. Should you encounter inconsistent data flow, only minor modifications are recommended.

•Fragmentation Threshold. This value indicates how much of the Router’s resources are devoted to recovering packet errors. The value should remain at its default setting of 2,346. If you have decreased this value and experi- ence high packet error rates, you can increase it again, but it will likely decrease overall network performance. Only minor modifications of this value are recommended.

•DTIM Interval. This value indicates the interval of the Delivery Traffic Indication Message (DTIM). A DTIM field is a countdown field informing clients of the next window for listening to broadcast and multicast mes- sages. When the Router has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. Clients for the Router hear the beacons and awaken to receive the broadcast and multicast messages.

•Basic Rates. The basic transfer rates should be set depending on the speed of your wireless network. You must select 1-2 (Mbps) if you have older 802.11 compliant equipment on your network, such as wireless adapters that support only 1 or 2 Mbps. Selecting 1-2 (Mbps), however, does not limit the basic transfer rates of faster adapters.

•TX Rates. Select all the rate at which you wish the Router to communicate within your wireless network.

•Preamble Type. The preamble defines the length of the CRC block for communication between the Router and the roaming Network Card. (High network traffic areas should use the shorter preamble type.) Select the appropriate preamble type and click the Apply button to set it.

•Authentication Type. You may choose between Open System, Shared Key, and Both. The Authentication Type default is set to Open System, in which the sender and the recipient do NOT share a secret key. Each party generates its own key-pair and asks the receiver to accept the randomly- generated key. Once accepted, this key is used for a short time only. Then a new key is generated and agreed upon. Shared Key is when both the sender and the recipient share a secret key.

Wireless Cable/DSL Router

•Station MAC Filter. This option will allow you to prevent wireless users on your network from accessing the Router’s functions.

Clicking the Active MAC Table button will display the MAC Addresses of all users on your wireless network. Addresses in green show access to the Router, while addresses in red do not have access.

To filter users, click the Edit MAC Filter Setting button.

Click the Wireless MAC Entry drop-down menu to select a range of entries for your network. From within this range, select the entry for which you’d like to manage access. Verify that the appropriate MAC Address is entered into the MAC Address field. Click the Filter checkbox beside that MAC Address. Now, this user will be prevented from accessing the Router. All other users will have access. To allow only that user and deny access to all others, leave Filter unchecked.
