Try Deleting the wireless card from Device Manager.

Beware though, if you do this all your wireless settings, such as network names and keys,will probably be deleted as well.

Then right click on the name of your computer and click scan for changes and that will then reinstall the card. Can't say it will help but it's woth a shot.

Check if any access list is set on router and disable it OR add your new PC MAC address to it.
Connect last PC to router using LAN cable: Be sure you can browse internet.check your subnet if you cannot.
Score this solution and let know if is fixing the issue.

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.

You have changed your TCP/IP settings and it cannot communicate with your wireless router.
Open the Control Panel, Click on Network Connections, then right click on Wireless Network Connection, then scroll down and click on to highlight Internet Protocol (TCP/IP), then click on the Properties button.
Select (click on) Obtain an IP address automatically

Try installing this driver first. It will automatically update itself so you dont have to bother with uninstalling it.

I have been working with Dell on this problem for quite some time. They tried replacing drivers, uninstalling and re-installing the card, replacing the card with a new one, etc, etc. Nothing worked. Sooner or later the error came back. Their last "fix" was to suggest that I restore the system to factory default condition and start all over again. I refused to do this. I had spent over 8 months adding software, tweaking it and windows, etc. They basically threw up their hands and gave up.

The Dell tech who replaced the card tried the solution noted here and "supposedly" it was fixed. A few weeks later the error came back.

So... I still don't have a fix for this problem.

If anyone finds one please let me know.

I'll check back here periodically.

Thanx,

Randy
