Hi, We have at our office a small network with 13 computers. The layout is pretty simple. We have a network case with the netgear swith, adsl router and a patch organizer. We are using cat5e cable with it's corresponding cat5e wall jacks. 7 of our computers are working perfectly, the otheres have trouble. Their NIC's have to be set to 10 Mbps to achieve connectivity, and some of them work but don't get even 2 Mbps. What kind of diagnostics or techniques can I use to find the problem? It's definately not the NIC's or Switch. We put new cable in one of those lines and still didn't work ok. Thank you in advance.
