Is the router secure with at least WPA2 AES personal security?
I'll forgo explaining the kid friendly hack tools and why it can affect just one machine and have folk making a post like yours.
I have an HP G61 Laptop running Windows 7 home. Over the past few months, my internet connections drops off, when I trouble shoot, it tells me there was a problem with the access point and that it is fixed. However with in minutes i lose connectivity again. I know it is not the router as we have several laptops that connect with no problem and stay connected. I have updated drivers, and have gone so far as to revert to factory settings to fix the problem. Not sure where I go from here. Any help would be appreciated as this is getting to be very frustrating.
