My technology knowledge is not good.
In my home there are three PCs in which two are wireless and third hard wired with a coax cable to a router/cable modem (Verizon). Yesterday, the wired pc missing its capability to attach to internet. It cannot locate any networks, and I cannot ping it. I do not want to blame my son, but he did attempt to install a security program (Kaspersky) which I had him take off.
Rather than having an IP address like 192.168.1.x, it has a different IP address that I do not know, but surely is not a 192.168.x.x Unfortunately, I have been attempting to repair it for about 4-5 hours and hopefully I did not mess things up too much. I called Verizon and they said as the other pcs are attaching to internet, itís not their problem.
Here question is that how can I know something that can repair through configuration, or if itís a hardware problem?
