Connecting a Edimax Wireless Lan Hi-gain 2.0 adaptor to my Windows XP desktop via a new Talktalk router

I have just received a new Talk talk broadband router  and tried to point my Windows XP old Pc to it as i have always had before via an old Edimax 802.11g Turbo Wireless Lan Hi-Gain USB 2.0 Adaptor. I have messed up the settings after it kept saying that i didn't have the authorising certificate.
After hours of frustration i removed the software driver supplied on a CD and re loaded,
It still does not work it just keep saying that the connectivity is limited or no connectivity and the router connection keeps dropping out.

When i am asked to put the network key in i try and input the numbers supplied by Talktalk in which is 8 letters/numbers it says that it must be 10 hex
I think it is because the adaptor is not talking to the route correctly
I am ready to throw the whole thing through the window can you help please..................

10 hex digits would be a weak (40 or 64 bit) WEP key.  WEP encryption was broken some years ago and should no longer be used.  Modern routers use WPA/WPA2 by default.

Your Edimax adapter may be obsolete and incapable of WPA.  Please check the model number, which should be something like EW followed by four digits.

WPA was supported in XP only after Service Pack 2.  If your XP system does not have SP2 installed, you'll need to install it before proceeding.

Please check the Edimax model number, and whether your XP system has SP2 installed.  Let us know what you discover.

Hi thanks for the reply
Ok i have checked i have the Windows XP service Pack 3 loaded

and the adaptor is Mac: 000E2E47DCE2.
 i purchased in 2006 so it is really old

Just as a matter or interest i have taken the base unit downstairs and linked up with an ethernet cable linked straight to the router. The connection is confirming local area connection speed 100.0Mbps

Unfortunately, the MAC does not help us determine whether the adapter is WPA capable.  Please check the model number, which should be something like EW followed by four digits.  Alternatively, the FCC ID will also work.

This adapter is WPA compatible.

The new router shipped with a default encryption key from the factory.  It is inadvisable to use that key, as you do not know how secure that information is.  The encryption key should be changed in the router's setup pages using a passphrase of at least 20 characters.  It is also advisable to change the router's wireless SSID to something that does not advertise what the router is.  A randomly chosen name is best.  If you wish, "_nomap" can be appended to the SSID so that Google does not use your router for geolocation.

A fictitious example is below.  Your router's setup pages will not look like this.

When connecting to the router, the connection should be made using encryption type WPA or WPA/WPA2.

Then try the connection again and let us know what happens.
