I would say remove and re-install the application/drivers.
What applications are you trying to connect with? If you use the one that can with the adapter then use the windows one if you use windows use the one that came with the adapter.
Try rotating the antenna, if it doesn't have an antenna plug it into another USB port.
Try installing either newer drivers from the manufacturer.
Are there any electrical items around the PC? Just like a fan can interference old school CRT monitor, the wireless signal can ge interfere.
If you are using the windows zero configuration utility restart the service.
Click on start, run type, services.msc, look for wireless Zero Configuration, right click and select restart and try the connection.
What OS do you have?
