The Linksys WUSB54G wireless internet card is an old piece of hardware.
After upgrading to Microsoft Windows 10 or 8, the gadget stopped working properly.
Microsoft Update installed drivers that would work for a few seconds, but then would disconnect repeatedly.
Fortunately, I found a workaround.
I located some community drivers for the WUSB54G.
They were intended for Windows 7, but I modified them slightly.
Use them at your own risk.
Im not responsible for any damage.
Also, for some reason, I had to rollback the drivers shortly after I installed these drivers.
Windows decided to update them without my intervention.
Since the rollback though, everything has worked solid.
