do you have a USB wifi adapter you can test on this computer?

SOURCE: how to change (or update) wap to wpa encryption on ASUS WIFI-B Network Adapter

With this Asus wireless B adapter even the new driver dont support WPA wireless security , because right now sicne WPA is a much newer and higher type of wireless encryption only some wireless B adapter supports that and sorry to say this wireless adapter that you have don't support it even with the latest driver so it will be better to get a new wireless G adapter that supports WPA 100% , you can get the wireless adapter from Asus or from other wireless device manufacturer like Linksys, Netgear. Dlink and Belkin....

SOURCE: can't load wua 2340 driver

Here is the correct driver install package, download the zip file to your desktop, then double click the zip file to get to the setup.exe file for the dlink adapter, first it may ask you if you want to remove the driver and all its components, say yes, go ahead remove all previous dlink drivers. Then, after the driver is gone(look in your program list to make sure its gone), doubleclick the exe file again to install the driver correctly, insert your usb adapter when prompted to. You are better off using this dlink adapter with an external base with a usb extension cable so you can mount in by your window(to catch the networks)
I am using it right now (wua-2340), it comes in low, but with a fast download speed even fast enough to stream video or audio.

Hi Antonio, you need to make sure your routers wireless settings match the settings of the computers wireless adaptor. Both need to be exactly the same.
