I am facing one problem in my layer 2 switch I don’t know
the problem is on switch side or client side. The problem is
some PC (not all) are stop participate in LAN they don’t
send or recd. Packet from switch and if I check RJ45 (with
LAN tester)from PC side the packet and 8 pin wire is working
fine and after that process of LAN tester I plug RJ 45 in PC
now PC start recd/ send packets what is the problem I don’t
understand even client side no virus found RJ45 is ok and
switch has no problem bcoz other PC is working fine Cable

in LAN tester and start working fine. Plz any one solve this
matter. And after lan tester process pc is working fine and
after 2 or 3 hour it again start same problem and again same
