You should check the settings on your router. If the laptop can connect to a wireless network somewhere else, you don’t have a problem on the laptop, necessarily. Do you have MAC address filtering turned on? Or maybe the DHCP address pool is all used up? Do some poking around and you might turn something up.
I turned off the mac address filter. Like I said it successfully connects once every 2 or 3 hours of testing?????? Confusing. USB device.
