Network keep droping ,ping time=-31ms

hi,

I have a system using POS system, but keep disconnect the network, I ping the router and keep getting time<1ms and time=-31ms, but all my other computer ping only time<1ms, is that mean network card has problem?

Network card, cable, switch, wall port..... Any number of things.

You need to start by eliminating each one.

Do you have another POS Near that you can swap the cable ends from one to the other?

Apart from all the other stuff that has been mentionend before and even if ping is not really vulnerable to it: did you check the duplex settings on switch and POS system (either auto/auto or fixed/fixed)?
