I have just bought a new modem DLink ADSL 4 ports all work but...I have four machines that were working on my old modem but now two of them do not work on their existing wiring. I can sling a CAT 5 cable to each of them and they work . After exhaustive trying Okam's razor says the cables are broken... But nothing has really changed from the old wiring -except unplugging the cables. Any ideas?
