Netbook won't connect to WPA2 protected network

Can anyone help? I 'm trying to connect my netbook to my wireless home network but it won't recognise the security key. I have Windows 7 32 bit installed. I have successfully connected it to my sister's network which is WPA2 protected, but when I try to connect to my own d-link dsl 2680 router, it keeps telling me that the security key or passphrase is incorrect even though I am typing in exactly the right password. My router is also WPA2 protected but for some reason the netbook fails to connect. My other laptop and my PC have no problem connecting at all though. It's just the netbook that seems to be the problem. It will however connect with a cable and also if I change the router's security setting to WEP. However I don't really want to leave it as WEP as this is less secure than WPA2. I've tried changing the SSID and password but it still won't connect. Before I installed Windows 7 I had XP running on the netbook and then it connected no problem. I don't know why I can connect to my sister's network but not my own. Any suggestions? Thanks.

Hi
Thanks for your reply. The D-Link is my broadband router not the internal WIFI card. However, I have updated the WIFI card using Windows Update. Had also tried updating it further using the method you described, but nothing was found. I also have the latest firmware running on my D-Link router.

Problem is it worked fine when I connected to my sister's Netgear router.

To fix this type of problem the firmware on the router usually needs to be updated.

The D-Link site for your router shows a firmware update made in 2010, that would be my first move to fix this type of problem. :)

D-Link UK | DSL-2680 Wireless N 150 ADSL2 Home Router

Thanks chev65 but the router seems to be running an even newer version than this, version 1.14t. The TalkTalk website (my broadband provider here in the UK) says this is the latest.

That's good then. I'm curious about the encryption being used. With WPA2 you should be using AES encryption rather than TKIP. Which one is the router and the wireless profile set to use?

Update: Nothing that has been suggested works. The router doesn't allow you to select TKIP or AES, it just gives the option of WPA, WPA2 or both. I've tried all combinations possible, changing the security settings on the netbook as I go.

So to see if it was the router or the wireless card, I have plugged in my old BT Homehub router, and the netbook connects first time. It accepts the password and is connected via WPA2 using AES. No problems. So does this mean that my D-Link router is a bit dodgy?
