Speed problem

By tech_soul7 ·
I have five workgrouped computers. There's speed problem on one of them (PC 2).
When I set speed to 100 full duplex or 100 half duplex the problem occurs.
I can ping local host but cannot ping any other host on the network (the network stop working).
Lenght of cable which is connected from PC 2 to switch is for about 30 meters.
When I set speed to 10 full duplex or 10 half duplex everything is ok.

what type of switch is it? It could be an autonegotiation issue where the switch is trying to autonegotiate but the workstation is forcing a specific mode. I have run across this using Cisco switches and Intel and Broadcom Ethernet cards. You must have the same settings on the switch and the card for it to work. i.e. auto/auto or 100full/100full etc.

It is small home network and switch is cheap one Micronet SP650K.
You cannot configure it only thing you can do is to turn it on and hope it will work.

Check that cable is rated either CATV or CATVI
Check pin out of cable should be either
wht/org, org, wht/grn, blu, wht/blu, grn, wht/brn, brn or
wht/grn, grn, wht/org, blu, wht/blu, org, wht/brn, brn
These are the pinout for 568B and 568A. 1 -8 (with clip down 1 is on left)

If it isn't an Onboard LAN connection try it in a different PCI Slot and see if that helps. If it's an ISA Card remove it and replace it with a PCI card and that should cure your problem.

It is Onboard ethernet card.
The pins are not in order you said it should be but if I change it for PC 2 than I must change pins for all computers on the netwrok am I right?
Cable is UTP CAT.6

If I understood this correctly I must use one of those two standards (568B or 568A) to connect computers to swtich.

Try a different NIC, differnet port on the switch, different cable. Process of elimination.

Also, try a program like QCcheck to test the actual speed. It could be reporting it's speed incorrectly.
