I think my problem started after upgrading my firmware some months (a year?) ago. Before that I could wake one of my computers (B) from the other (A) by issuing: % wol aa:bb:cc:dd:ee:ff but now when I do this I just receives the following error message: wol: Cannot send magic packet for 'aa:bb:cc:dd:ee:ff' to 255.255.255.255:40000: No route to host It even happens when I sent the wol package to itself (that is first I try to send a wol package from A to B which doesn't work. Then I try to send it from A to A and I am still told that there is no route to host). All machines are Macs running 10.4.11 (or whatever the latest version is). The router is a WRT54GS with official FW 4.71.1. A and B are both connected with wires to the router. A also has internet sharing enabled through its wlan interface.
