For starters, verify that your router and your workstation are using the same

SSID descriptions. SSID acts as a password when a mobile device tries to

connect to the wireless network. The SSID also differentiates one WLAN

from another, so all access points and all devices attempting to connect to a

specific WLAN must use the same SSID. A workstation will not be permitted

to connect to the network unless it can provide this unique identifier. This is

similar to the function of your network's Workgroup or Domain name.

When you're experiencing conductivity problems, it is always best to keep

things simple. So next you are going to do is that, please disable any WEP

encryption you might have configured.

Successful implementation of encryption also includes the use of a shared

key. A HEX key is the most common, but other formats are also used. This

key identifies the workstation to the router as a trusted member of this

network. Different manufacturers can implement this key technology in ways

that might prevent them from working correctly with another vendor's

products. So pay attention to detail is going to be the key to a successful

installation.

Next make sure the router and the NIC are configured to use the same

communications channel. There are normally 11 of them, and the default

channel can also vary from vendor to vendor. You might also want to confirm

that the router has DHCP services enabled and an address pool configured.

If not, the NIC won't be able to pick up an IP address. I have run across a

few access points that offer DHCP services but do not assign all of the

needed IP information to the NIC. As a result, I was able to connect to the

network, but could not browse the web. The point is, don't assume anything.

Verify for yourself that all of the required settings are being received by the

workstation.

Finally, you might want to keep the system you're trying to configure in the

same room as the router, at least during the initial configuration, in order to

minimize potential interference from concrete walls or steel beams.

• My PC can’t locate the Wireless Access Point.

A:Check the following:

◦ Your PC is set to Infrastructure Mode. (Access Points are always in

Infrastructure Mode.)

◦ The SSID on your PC and the Wireless Access Point are the same.

Remember that the SSID is case-sensitive. So, for example

“Workgroup” does NOT match “workgroup”.

◦ Both your PC and the Wireless Access Point must have the same

setting for WEP. The default setting for the Wireless Router is

disabled, so your wireless station should also have WEP disabled.

◦ If WEP is enabled on the Wireless Router, your PC must have WEP

enabled, and the key must match.

◦ If the Wireless Router’s Wireless screen is set to Allow LAN access to

selected Wireless Stations only, then each of your Wireless stations

must have been selected, or access will be blocked.

◦ To see if radio interference is causing a problem, see if connection is

possible when close to the Wireless Access Point. Remember that the

connection range can be as little as 100 feet in poor environments.

• Wireless connection speed is very slow.
