Wireless adapter sees, but will not connect to network

I have an Asus USB-N13 wireless adapter for my PC, I'm running on Windows 7 Ultimate and I have been having problems connecting to the internet. I currently have the latest driver for the adapter. The problem is that even though i can see all the available networks, it will not allow me to connect to my network. All other computers/laptops/phones can connect to the network no problem. When i run the Windows trouble shooter, it simply says that there is a problem with the adapter or access point. I know that my network key is correct so that wouldn't be the problem. The internet works fine if an Ethernet cable is used.

-Thanks

    First step turn off the encryption, then try to connect, does it work now? If not AND does work via ethernet then something is the matter with the wireless adapter most likely. If when encryption is off and your within 5 feet and works fine, then walk the system around, do you drop signal? This can be for any number of reasons. If encryption is off and your connecting now, then try with encryption (WPA2) again, typically it sounds like the password is just mistakenly incorrect as the issue.

    I disabled the encryption and it connected, strangely though, when i put the encryption back up it failed to connect again. The network key that i was using is the correct one as written on my router, all other devices work when using the same key.
  3. That basic test tell you were the problem was. Sounds like to me that your encryption either in Windows or used on the router is a problem. Vista forward implement WPA2 AES security, if the router isn't set right it may be using older WPA or TKIP and maybe the conflict. Obviously the router AND USB work, your just not getting them to speak perfectly to each other. You may also just try to change the encryption key to something else easier to type and see what happens then, otherwise read the Router manual (or is this router from the ISP?) on setting up encryption and see what options you have.

    The router is from the ISP, it uses WPA-PSK (TKIP) and WPA2-PSK (AES), the computer is also set up for WPA2 AES security, i have tried changing the encryption key with no success.
  5. Then either a reload of Windows is necessary, or contact your ISP for help. It should be WPA AES normally, but the test we just did also is a key indicator, where you can prove without the encryption it works, wired it works, but anytime the encryption kicks on it doesn't work. The other choice is return the USB and get a different maker / brand and see if it just that USB device can't handle the encryption
