Dell 1.66Ghz 1GB Ram laptop
Intel PRO/Wireless 3945ABG Network Connection
Windows XP SP2

I have a wireless connection at home with a number of laptops connected, have all been working fine for a year or so. One of the laptops has stopped connecting to the internet and I have searched high and low for a solution.

The adapter (Intel PRO Set Wireless) has an icon saying I am connected to my provider at 54mbps with an 'excellent' signal quality but the ip address is set at 169.254.195.180. Another icon in the tray starts stating 'acquiring network address' for a long time and then fails stating 'limited or no connectivity'.

Using the various troubleshooters, I have received a message stating 'the wireless adapter failed to get a valid ip address. This can be due to authentication failure, incorrect wireless security passwords or because of a DHCP server malfunction'. I have re-entered the correct passwords to no avail, and the other 2 laptops are working and connecting fine to the same provider.

I have also tried the cmd prompt and the usual ipconfig release and renew but it simply states:

>ipconfig /release

sconnected.

An error occurred while renewing interface Wireless Network Connection : unable

I have also tried the WinsockFix and IspFIx programmes available on the internet for download. Again no success!

On my Sony vaio laptop, which is working fine, I get the following details:

Wireless LAN adapter Wireless Network Connection:

Anybody have any words of wisdom before I throw the laptop out of the window!
