Dell Latitude C400
Dell WLAN 1300 Wireless G Mini-PCI card
Windows XP SP2
Problem – Wireless hardware will only work using native Dell wireless utility. With Win XP managing connection, I can only get connectivity from wireless router, (green bars in systray) but cannot get DHCP IP address assigned on client. Have tried all usual remedies such as ipconfig /renew, /flushdns, etc. Also tried stopping/starting Win XP Wireless Zero Configuration service, uninstall/reinstall of Dell WLAN 1300 driver and have tried different driver versions.
I have also tried uninstalling and removing Dell mini-pci card and using Linksys cardbus wireless G card. Same result. Can only get DHCP assigned IP address using Linksys native utility.
All other wireless clients at this location are working normally and nothing has been changed on wireless router. I do not use MAC address filtering and problem persists even with WEP encryption turned off at router.
I would appreciate any suggestions. Thanks.
