My friend's laptop, cable network works fine; she bought a D-Link PCMCIA Wireless Lan card, connect to wireless network at home. the driver was installed no problem, and firstly using Windows wireless configuration, after put WEP key, SSID and save, it pop up an alert said" at least one change wan't applied to the wireless settings ". It sounds like a group policy thing, but the system is xp home; then we disabled the windows wireless configuration by disable the zero wireless service, and use the utility comes with the Wireless lan card, this time, it seems connected, it got the proper IP , gateway and DNS, but no internet, keep saying "can't find the DNS", but from the connenction details, the DNS IP is there, Primary secondary.we plug the network cable again and it works fine with cable connection.After that, I tried an Asus USB wireless card, it did the same thing. i am thinking there must be that policy problem, but it's a xp home edition and not in a domain. Thanks for help My laptop with wireless connection is working fine, so the wireless router is no problem thanks for answers, the firewall has been disabled, even avast. I can't do any changes to the "windows default wireless configuration", It just like be locked up. I am really exhausted. the driver and utility has been installed many times, never works. Thank you for the answer, from the network scan, I can see the wireless network, when hit "connect button", it pops up ask me to change the ac hoc to infrastructure network, but it doesn't save any changes I made, just says"at least one change not applied to the wireless settings" this scenery is normally happened in a domain environment, when a domain policy is applied on the workstation, and the policy is prevent user to change the wireless settings. but this time, it is a windows xp home edition(no domain function),no local group policy configuration. I searched google and others, perople get the same problem when they install the xp sp2, So I remove the service pack2, but the wireless still not work in sp1 mode; I have to reinstall sp2, and unfortunatelly it's not help. At last we can only suffer on cable connection, I haven't tried to reinstall the system, it would help I suppose, but not wise enough.

FIREWALL settings may be to restrictive. If the only firewall running is Windows Firewall, then disable it. Everything should work fine.

It's difficult to imagine what's happening without checking the laptop but I guess is something related with the first experience you made trying to use the Windows applet instead of the proper D-Link application. Uninstall the device and all the related drivers and software, clean your registry, reboot and perform a fresh device installation. Configure using D-Link's driver and software and you should be fine.

Ok so if the router is fine it is already set up with a SSID, RIGHT??? THEREFORE, YOU DON'T NEED TO SET UP A WIRELESS CONFIGURATION IN WINDOWS. now, when you turn on the computer with the wireless card, open up the software that runs the card, search for a connection...and the SSID on the router that is broadcasting a SSID should show up. then just hit connect. Make sure you do NOT try "ad hoc" connecting. if the router has a password, then you need to know if it is wep or whatever, and the software that comes with the wireless card will allow you to enter these parameters as well. Now, when it comes time to trying to do file sharing and print sharing in windows XP home..you need to just set up a network...not wireless....and then do two other things... first turn of any windows firewall settings, and also, if you can get into the files at all..I was trying to network an 2000 with XP home edition, I had to set the GUEST account in windows XP home edition to be an administrator!!!! Anyone coming into XP home edition is a GUEST!!

The external wireless card(s) may need to be configured with the wep key that you made up. It happened here with another computer. Use wpa if you can. It is more secure, and never get online without a firewall (only one).
