What is a loopback cable ?

after i assign IP address(Ex: 192.168.0.1) to my pc, I can't ping using the ip that i have assigned unless i connect my computer to a hub.

I heard that we can make a loopback cable using UTP and we just connect one end of that cable to the pc and no need hub and then we can ping the ip that we assigned to that pc.

So i followed their instruction to make the cable, but it doesn't work after i connect this cable to my pc.

Please help,


Thanks,

Ping (ICMP Request) is not a broadcast.  It's a Unicast.

You CAN ping your own computer without connecting it to anything.  If you can ping the loopback address (127.0.0.1) this indicates your TCP/IP stack is functioning.  If you cannot ping the NIC, with a static address set, this indicates the NIC is malfunctioning in some way.  You do not need a loopback plug, or to have it connected, in order to ping it.

You DO need the loopback plug in order to perform certain types of diagnostic tests - usually included with the NIC driver.

Nsophat, you may want to try swapping out the NIC.
