Latitude D630 cannot find wi-fi networks

Hello,

I have an old D630 running windows XP. It was working fine until for some reason the operating system became so slow i had to reinstall windows. After that i installed all of the missing drivers but for some reason the wi-fi driver is not working properly because my laptop cannot detect any wi-fi networks even though in my apartment my devices can find 5-10 wi-fi networks at any given time.

I think it has something to do with the WLAN utility - i did not have it prior to reinstalling windows and my wi-fi worked fine. Also for some reason, while the driver is installing the windows wi-fi connection program icon on the bottom right corner appears and says that is actually can find wi-fi networks in range. I even managed to connect to my house wi-fi network while the installation was in progress and it worked fine - however, when the installation completes my laptop cannot find any wi-fi networks. So does it have to do with the WLAN utility? Disabling it does not work, deinstalling it removes my driver as well, and by the looks of it, my Dual-Band 1490 WLAN mini-card works fine. 

Any help is appreciated!
