Trouble shooting PING This section discusses possible solutions using ping command to find your problem if you can’t connect to the network. 1. Check if you have a valid IP address 2. Test if your TCP/IP works. Under MS-DOS (command prompt), type “ping localhost”. If you didn’t receive a reply, then you need to re-install your TCP/IP. Proceed to next step if you have received replies. 3. Using the same procedure, try to ping your Wireless Adapter’s IP. If the Ping command fails, check the following: • Your WLAN is connected • Check that your driver is correctly installed.
Checking Valid IP Addresses There are restrictions on which IP and addresses you can and cannot use. Some IP addresses are reserved for testing, multicasting and some IP are restricted by your ISP. Following IP addresses cannot be used: ¾ 127.x.x.x – this is a loop back address, used for testing ¾ 0.0.0.0 – this IP address represent the host address ¾ 255.255.255.255 – this is local broadcast address ¾ First portion of IP cannot exceed 224, that is, IP addresses which is in the range of 224~239.x.x.x is not valid. This range of IP is for multicasting. IP range from 240~255.x.x.x are reserved IP addresses and cannot be used. ¾ 0 or 255 in host ID portion of your IP are not valid. This represent local host or broadcast address for your class of IP IP has five classes, namely class A, B, C, D and E. For each class, the host ID portion in the IP field is different for each of the classes. Figure below illustrate this. Class A: 1 ~ 127 . Host ID Class B: 128 ~ 191 . X . Host ID Class C: 192 ~ 223 . X . X . Host ID Class D: 224 ~ 239 . Used for Multicasting (no Host ID) Class E: 240 ~ 255 . Reserved IP address Host ID cannot be all 0’s or all 255’s. Note: X denote don’t cares in the above example.
Federal Communication Commission Interference Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures: - Reorient or relocate the receiving antenna. - Increase the separation between the equipment and receiver. - Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. - Consult the dealer or an experienced radio/TV technician for help. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
