WOL Not working on older machines...
We have some older (5 years) Dell optiplex 170L's, and some older Stone Computer Workstations, that are refusing to WOL.
We have checked the BIOS settings, and they are correct. We have reset the BIOS, and changed the battery, and matched the settings against a working machine. On the Stone machines, we have even tried a BIOS upgrade, which doesn't work consistently...
We have checked and triple checked the MAC Address on the clients, and even used a WOL packet sniffer to make sure the machine(s) are receiving it (which they are). We have tried new network cables/patch leads, and even tried switching the wall socket to the working machine next to it and it still fails.
Is it down to the motherboard/network socket being tired/worn out through use? If so, I might have to resort to using the BIOS wake up instead :(:rolleyes:
We also do not have any VLANS setup (as yet) and I have checked the port configuration on the switch, which appears fine. I even turned off spanning tree protocol as a guess, but no luck
