Lately,I bought a new computer to replace old one in my office.
The pc is far from hub
It is about 10 meters
It showed “connect failed”
Ping host”192.168.1.1″,lost four bags
But the light of network card is ok
The computer is ok when is connected with other network line
So there are not problems in network card and net work line
Suddenly,I remembered network card pattern makes network lingering when the network line is so long between two PCs.
So I changed the netword card parrern as 10M
It is ok!
