Try this..1.Try to uninstall the USB adapter and re install it again. To do this go to Add/Remove Programs under Control Panel and find the usb adapter your install in this case its Alfa Wireless USB Adapter and uninstall it and restart your computer after uninstallation. 2. Remove the USB adapter while restarting and insert it again until windows already loaded and all windows startup program have all been started.
3. System will look for the system driver of USB adapter and it will prompt you for the driver location in this window do not choose the recomended instead click browse and locate the driver cd and look for driver folder and select the applicable driver for your operating system such as WinXP if your using XP.
4. If there is no driver folder in cd, go to my computer, explore cd and run setup or install this will install the pending driver installation.

Go to the Device manager and bring up the properties to the realtek 8185 device. There is a tab called Power Management. Click on this tab. There is a checked checkbox that says Allow the computer to turn off this device to save power. Uncheck this box. This should stop the random disconnects.
