Does the dongle have Windows 7 drivers? Check in device manager see if it's listed there with any errors. Try a different USB port also. If none of that shows or does anything, try it with another PC. If that does not work, replace it.
yes the device shows in windows device manager
NEVERMIND THE WIRLESS OPTION ON MY ROUTER WAS TURNED OFF
So when you said nothing was showing up, you were not talking about the WiFi dongle but the wireless network list? From what you wrote it sounded like the WiFi adapter was not showing up on the computer.
Glad it's working for you now.
no no no the wireless usb thing didnt pick anything up
also, why didn't it pick up my neighbours wireless ??
maybe its just really bad and can only pick up really close connections
WiFi has about a 300ft max range, lowered by walls and such. Plus the others may have WiFi shut off, or set to not broadcast the name.
