Any number of variables can keep your workstations from talking to each other.
Let's go over some of more common ones.
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.
