Try With A different wall Socket

If the lights are still OFF

Then call 1800-223-5546 and ask for a replacement

check the wireless settings of the router .
Make sure that you are typing the correct network key if your network is secured.
May be you will need to open the ports on the router.

Hi,

Upto 1.5 mts is OK and u require a cross over cable to get an connection.

That message means that your wireless security key has been changed to a different password. All you need to do is go to Network and Sharing Center > Manage Wireless Network, then delete all the listed wireless profiles there. Now click on Add > Add a Network that is in range of the computer > Choose your network and connect. Make sure to type in a correct network key. That should do it.

In some cases, older 802.11b clients may not be compatible with 54g wireless. These adapters tend to be of lesser design or use older drivers or technology. 54g-LRS (Limited Rate Support) allows these clients to be compatible with the newer 54g technology. Switching to this mode can solve problems that sometimes occur with these clients. If you suspect that you are using a client adapter that falls into this category of adapters, first check with the adapter vendor to see if there is a driver update. If there is no driver update available, switching to 54g-LRS mode may fix your problem. Please note that switching to 54g-LRS mode may decrease 54g performance. It is not recommended you use this mode unless you have a very specific reason to do so. This mode exists only to solve unique problems that may occur with some 802.11b client adapters and is NOT necessary for interoperability of 54g and 802.11b standards.

As with any wireless protocol, 54g has overhead associated with it that limits performance. While signaling data rates of up to 54 Mbps may be achieved, like most shared media (e.g. Ethernet) throughput will be significantly less. There are two scenarios for 54g performance. In an environment with only 54g clients, throughput can exceed 24 Mbps. This performance is equivalent to that of 802.11a, although 54g is usually available over a greater range. The second scenario is where 802.11b clients are present. RTS/CTS flow control must be used to allow 802.11b clients to recognize and establish communications with 802.11g access points. This leads to delays in transmission and drops peak throughput to about 10 Mbps. 54g performance is still well in excess of the maximum measured speeds of 4-5 Mbps for 802.11b. The use of RTS/CTS is important because it provides determinism to the wireless network, ensuring a minimum bandwidth for each user. Like Ethernet, 802.11 LANs normally use a ג?œcarrier sense media accessג? mechanism to signal transmission without asking for permission from the network. As the network becomes highly loaded, collisions occur more frequently and the network can become saturated with packet retransmission attempts that eventually make it impossible for any data to get through. RTS/CTS provides a more formalized flow-control mechanism that avoids this problem.

54g products will perform differently depending on whether or not there is 802.11b traffic in the immediate environment. The rules-of-thumb for throughput are: In an 802.11g-only environment, throughput will be between 4-5 times the throughput of an 802.11b network. The maximum throughput can exceed 24 Mbps. In an environment that includes 802.11b devices, throughput will be about double the throughput of an 802.11b network. The maximum throughput can exceed 10 Mbps. In addition, all 54g radios have better sensitivity than current 802.11b radios, and 54g provides outstanding coverage in its 802.11b compatible mode.

54g is Broadcom's maximum performance implementation of the draft specification for IEEE 802.11g wireless networks. This technology is expected to quickly become the next mainstream wireless LAN technology because it works faster and farther, is backward compatible with 802.11b and is affordable. Authorized products displaying the 54g logo use Broadcom's 54g wireless LAN chipset and ensures that products are designed to be completely interoperable at maximum performance with other 54g products and are compatible with the draft IEEE 802.11g specification.
