After a very strong lightning strike we lost all our network connections (routers, switches and NICs working with CAT-5e in desktop connected to computers). ). I then decided to use them as detachable Ethernet ports. They install quickly on Win7. The good news is that they work and are inexpensive. The downside is that they're 10/100 speeds, not gigabit.
