You havent quite describe the type of connection problems you are having so there is quite a variety to check.Your Pcs should show if the cables are connected or not right? Guess thate where you should start. In case of concrete help, you need to describe the exact issues you are having.

its simple

when user connect their lap top to wall outlets . they are unable to connect .

how do i trouble shoot .

1) i need to check the health of cable from end to end .

2) if this succeed . then i can move to switch for checking layer 2 configuration .

i need some best cable testers that can detect loss of signal form one end to another end.
