Hello, when you installed the drivers for the WiFi, do you sense it alone? Was it Windows Update? Did you installed it? What I suggest is that you install the drivers for Win7 manually if you can from the Device Manager, doing the manual install and load the inf, but I not gone with Win8 and the PenWifi that I currently use, but the earlier they used and I finish fastidiándose and always got me into trouble, in WinVista and Win7 downloaded an updated driver for Windows Update, since the originals were for XP64 drivers and had no official vendor support for Vista and Win7
The drivers you downloaded from WU go redundancy annoyed connection have prevented that would connect, after installing it was impossible to connect back to the network, when retreating to the original driver XP64, everything returned to normal, you have such evidence, download drivers Win7 64bit HP official website and refer to your laptop, and I have seen that there are many models HP G61, and install manually, it may be that.
To go to the Control Panel or Device Manager more directly, in the lower left corner, where you would click to go to the start menu, right click and make a shortcut will be displayed very nerve system shortcuts.
