Greetings,

Does anyone know the best way to track what is causing a wireless device to
drop from SSID or go to the Limited or no connectivity state? We have a few
different types of devices, Wyse thin client with Cisco a,b,g cards, and
Lenovo laptops that use the Intel pro wireless. We are seeing that they will
have 100% Signal Strength, Excellent Signal Quality and running at 54.0 Mbps
but they disconnect and then get the 169.254.x.x address. We either have to
repair the connection or restart. We have the latest drivers from Lenovo and
all the latest Microsoft patches. I read that we can enable logging within
Windows Xp but the log looks a little confusing. Any ideas how to narrow down
if it's the client or if it's something with the access point and beyond? I’m
responsible for the desktop side and the network group keeps telling us it’s
the client and we need to figure out what to do next. We also have the
settings on the client set for no power management and we have tried setting
the roaming aggressiveness to high.


Wireless Properties:
Network Authentication - WPA
Data encryption - AES
EAP type - Protected EAP (PEAP)
Validate sever certificate
Enable fast connect
Secured password (EAP-MSCHAP v2)

To troubleshoot limited or no connectivity issue, try these:

1. Obtain and install the most recent version of the wireless network adapter driver and/or wireless router firmware..

2. Re-configure NIC speed.

3. Install Microsoft wireless update

4. check the wireless security settings or windows security software settings.



These links may help too.

Hi Robert.

1. I just wanted to go over the steps you suggest. We do have the latest
driver for the Wireless adaptor but we use Nortel Access points at the place
I work, so I can do nothing to them. It's hard becasue we tweak the clients
over and over and the people that handle the AP's keep saying it's client
issues.

2. Im not sure what you mean by nic speed. We have adjusted the roaming
aggressivness and changed the power managment so that the nic is always on
and running at full power. Any other suggestion would be great in this area.

3. As far as the Wireless update, we have XP SP2 loaded and the WPA2 update
installed. The image has all the latest patches from Microsoft as well. Am I
missing anything if I have SP2 and the WPA2 patch loaded?

4. The wireless security settings I'm not sure where to chesk that. Can you
help me out in this area at all as far as checking this? I only have access
to client side settings and security.

Thanks for the links...I will go through those now and see if anything helps.

Thanks for all your suggestions.
Dave
