Linksys Wireless network drops connection with XP service pack

[Tom]

I am using a linksys wpc11 wireless Pccard with windows
XP. Everything works fine until I install the XP service
pack. With the service pack installed I get the network
dropping from time to time and then coming back a few
minutes later. This can happen as frequently as every two
minutes or as infrequently as every two hours.

Make sure 802.1x autheneication is turned off..

In Windows XP SP1, a change was made to this authenication method such that
wireless connections that had this option enabled would have its connection
dropped after 3 minutes if the connection could not authenicate against
802.1x credentials.

To disable 802.1x authenication over your wireless network card...

1.. Click Start, point to Connect To, click Show all connections, and then
double-click your wireless network adapter.
2.. On the General tab, click Properties.
3.. Click the Wireless Networks tab.
4.. Under Preferred Networks, click your home network, and then click
Properties.
5.. Click Data encryption (WEP enabled).
6.. Click the Association tab, and then click to clear the Network
Authentication (Shared mode) check box and the The key is provided for me
automatically check box, if they are selected.
7.. Click the Authentication tab, and then click to clear the Enable IEEE
802.1x authentication for this network check box, if it is selected.
8.. Click OK two times to accept the changes.
