Dell Latitude D 410 has suddenly (worked yesterday) stopped connecting to all known (and working) wireless networks. Is my internal wireless card gone?

So u can connect to the router, but you arent allowet to access the internet?
The router gave your dell a new ip-number, but it dident gave you access to the net. You ned to do the settings in your router manual, let the router give your dell full access.

Good luck

Hi car7924,

First, make sure that the wireless switch on the left side of the computer is turned on (this should make the WIFI light go on -- beneath the lower right corner of the screen). If it doesn't work, then try going to Start Menu > Control Panel > Network and Internet Connections > Network Connections.

You should see the Wireless Network Adapter in the window that comes up. If you don't, you need to download the driver for that adapter. The most common adapter in the D820 is the Dell 1390 WLAN MiniCard, and the driver for it can be downloaded at the following web address:

If, on the other hand, you do see the Wireless Network Adapter, but it says "Disabled" underneath the name, then right-click it and select "Enable." This should make it work.

I hope this helps - please let me know if I can be of any further assistance.

Kind regards,
H2H

The 1390 WLAN Minicard may not be configured to communicate with your wireless router.
Check the wireless router settings, (check the wireless settings on your other computer) and configure the 1390 WLAN with the same settings eg. SSID, WEP/WAP encryption, etc.
Is MAC address filtering enabled on your wireless router, if so add the MAC address of the 1390 WLAN to the MAC address list in the wireless router.

Check the TCP/IP properties of the 1390 WLAN card the Internet protocol should not have a fixed IP address, set it to Obtain an IP address automatically including the DNS.

Use the Ipconfig command to see the IP configuration of the network cards.

Use the Ping command to see if you can communicate with wireless router.

I have solved the issue by following the instruvtions of worldvet with the NIC unplugged I installed the latest drivers provided by cornyn, now everything works fine again.

The problem came into place when updateing Windows XP to SP3 with all other patches, so I assume there was a wrong dll or something.

I also installed all other drivers updates from dell including BIOS to avoid this behaviour in the future,

Have you run the Dell Diagnostics test? reboot the computer and hit the F12 key, scroll down to the diagnostic option and run the test, it will check hardware and memory etc.
