Re: Wireless Issue

In article <#6xMMGdzGHA.5048@xxxxxxxxxxxxxxxxxxxx>, g@xxxxx says...

I just installed a wireless network using an D-LINK access point plugged
inside my network. It works great when I have not security however when I
use encryption my clients can connect but it say limited or no connectivity.
Any ideas why?

George:

"limited or no connectivity" usually means the NIC (the wireless NIC in
this case) cannot get an IP address from a DHCP server.

Since the wireless connection is working OK with no security, the first
thing to check is whether the security settings on the DWL-7100AP and
the client PCs are EXACTLY the same. This is especially easy to get
wrong if you are using the older WEP security. Entering those long hex
keys is a real pain and it is easy to make a mistake. The DWL-7100AP
supports the newer WPA security, which is both more secure and easier to
configure. You should use that unless you have a REALLY good reason not
to.

You say the AP can be used by both domain clients and non-domain clients
(what I refer to as "guests" or "visitors"). In general, it's not a
good idea to allow non-domain clients to connect to your domain network,
especially a wireless network. You have no control over whether non-
domain clients are properly patched or are even running anti-virus
scanners.

The DWL-7100AP supports a sophisticated security method known as 802.1x
authentication using Extensible Authentication Protocol-Transport Layer
Security (EAP-TLS) and WPA encryption. If you want step-by-step
implementation instructions, including sample network diagrams that show
how to support "guest" PCs, see the following:
