How do I change WEP to WPA to fix network connection?

[Patrick V]

My Belkin network adapter (F5D9050UK) recognises my home Airport network (and
the networks of several neighbours). Device Manager says the Belkin is
working correctly. However, it won't connect to the WWW. It prompts for a WEP
password, which I enter, and which works for other XP computers in the
network but then fails to connect this one, with the message 'Connection
failed'.

The diagnostics say that the problem can't be fixed. I've downloaded the
latest drivers from Belkin and installed them and I've had this network
adapter working on this PC before a system restore. I want to change the WEP
setting to WPA in case this is the problem, but I can't find the option
anywhere to change the WEP to WPA or to try the TKIP option. I go to network
center, but none of the options seem to allow me to go anywhere near the
WPA/WEP/TKIP/AES settings. Help.

Hi
It seems that something is wrong with the Wireless setting of the computer.
May be this can Help.

As for Wireless Security.
From the weakest to the strongest, Wireless security capacity is.
No Security
MAC______(Band Aid if nothing else is available).
WEP64____(Easy, to "Brake" by knowledgeable people).
WEP128___(A little Harder, but "Hackable" too).
WPA-PSK__(Very Hard to Brake ).
WPA-AES__(Not functionally Breakable)
WPA2____ (Not functionally Breakable).
Note 1: WPA-AES the the current entry level rendition of WPA2.
Note 2: If you use WinXP and did not updated it you would have to download
the WPA2 patch from Microsoft. http://support.microsoft.com/kb/893357
The documentation of your Wireless devices (Wireless Router, and Wireless
Computer's Card) should state the type of security that is available with
your Wireless hardware.
All devices MUST be set to the same security level using the same pass
phrase.
Therefore the security must be set according what ever is the best possible
of one of the Wireless devices.
I.e. even if most of your system might be capable to be configured to the
max. with WPA2, but one device is only capable to be configured to max . of
WEP, to whole system must be configured to WEP.
If you need more good security and one device (like a Wireless card that can
do WEP only) is holding better security for the whole Network, replace the
device with a better one.
