Maybe "Wireless Zero Configuration" in Windows will be recipe for your problems, without dedicated application.

How do I find that? I don't understand.

You can configure WZC (wireless zero configuration) in your computer:

1) Type services.msc in "run" and enter.

2) Select wireless zero configuration from the list which appears in the next window.

3) Double click on that option , and do whatever setting you want to do.

It doesn't show up in that list. :/

I just installed Windows 7, when I put the CD in, it says "Wireless network adapter is not detected. Please insert the right TP-LINK wireless network adapter and click yes to continue installation, or click "No" to quit installation progress." It's defo plugged in, tried all different ports and no luck. When I plug it in it also now says at the bottom of my screen "USB device not recognised." Please help, this getting beyond a joke now.

Have you installed "chipset drivers" for your motherboard?

I don't really know. Sorry, I'm not the best with computers.

I don't know model your motherboard, I know only your operating system and wireless card - WINDOWS 7 and Tl-wn725n

What should I try next?
