wlan problem with xp

Point value changed by question poster.

Try this.

Go into the network card properties and Click the Authentication Tab. Uncheck "Enable IEEE 802.1x

This sounds like a wild problem I have seen before. It's worth a shot :)

Technet article 302088 says:

Wireless Network Adapters May Lose Connectivity When They Appear to Be Functioning
The information in this article applies to:
Microsoft Windows XP Home Edition
Microsoft Windows XP Professional
Microsoft Windows XP 64-Bit Edition

This article was previously published under Q302088
SYMPTOMS
A wireless network adapter may lose its IP address and, as a result, may not have any network connectivity to access the Internet or browse the network.
CAUSE
This issue can occur if the Service Set Identifier (SSID) for that network has not been added to the list of preferred networks. This can occur if infrastructure networks are detected and wireless detection has been set to auto configuration (the network has not been previously associated with and has not failed an 802.1x authentication attempt).
RESOLUTION
To resolve this issue, add the Service Set Identifier (SSID) of the network that you want to use from the Visible Networks list to the Preferred Networks list:
In the Network Connections folder, right-click the icon for the wireless connection that you want to use, and then click Properties.
Click the Wireless Networks tab, and then click Configure.
In the Network Name (SSID) box, type the SSID that you want to add, and then click OK.
If the SSID is not known or not yet detected, you may experience reception problems. When an SSID is detected, a message announces the SSID in the notification area, where you can choose the SSID for use.

You can also:

Right click the Network Interface Card (NIC), chose View available Wireless Networks, then click Connect. It is automatically added as a prefered network.

I have heard of several situations where xp has had some problems networking with 2000. in my personal experience, i had the problem too, and it was very beneficial to just upgrade the 2000 users to xp. if that doesn't work, then you should look at getting different network cables/cards for your computers. Sometimes you might have a damaged cable. also, you might want to look to see if there are any special drivers that you can use to help your network card function better.

Make sure that you don't have some kind of power saving feature enabled for the card. My wireless setup has a power saving feature in it's properties.

Also besides the power savings on all devices including NIC's , check to make sure that there is no Battery or AC problems.

Has Event Viewer helped out with any errors?

We had this problem before. Make sure the DNS server is correct and working. Then set the DNS on the XP to point to the DNS server (your w2k server possibly). Do this in the local area connection properties, IP protocols, click advanced, click DNS tab, and add and enter the IP for DNS server. Must be first on the line.

I had a similar problem with an XP hardwired to the lan (W2K PDC) using DHCP. The PC would be connected to the lan for a couple of hours then for some reason it would no longer be on the lan. I finally gave up and assigned the XP a static IP address and it has not had a problem since. Later, if/when I have more time I hope to either see the answer on this website or figure it out myself. Good luck.

If your WLAN unit has firewall protection, you will have problems most likely with Win XP. The problem would be with Win XP's built-in firewall (needs to be disabled). I just installed a wireless router (firewall built-in) on a small network and every XP machine had no Internet connection most of the time. As soon as I disabled XP's firewall, every connection has been 100% stable. Also, my firewall software on one XP machine had to be uninstalled and that resolved the only other issue.

Only one firewall is needed as long as it is setup correctly for your needs.

Hope this helps. Good luck.

Take a look at your powermanagement of your wireless lan adapter. Switch this to 'OFF' at the properties of the device in Computer Management. You can find it on the advanced tab under Card Powermanagement.

Maybe this one will help:
