>>> 1. are the lights on or flashing with a cable plugged in and pinging >>> something valid?
>> No. They are stable > That indicates a problem - if a packet is going out/in, the lights > shouls flash Excuse me; I looked only half a second!!! Yes they are flashing. Since this night I found something important: the little box put in the socket wall from where the cable goes out, doesn't no more work!!! When I put it on my two other PCs they can't connect to internet. For this reason I use one of the boxes, which works, on my desktop. Between this one and my laptop pings are ok. The two PCs can recognize each other. But, on my desktop I don't have yet internet connection. Is the network card even so out???
