It is neither fedora, nor windows xp nor windows 7. It is the router from at&t. I repeated the following process: power cycle the router wait until the network is re-established on all clients. then ping from to works? ----------------------------- xp1 fedora yes fedora xp1 yes xp1 win7 yes win7 xp1 yes win7 fedora yes fedora win7 yes Then I waited about 20 to 30 minutes ping from to works? ----------------------------- xp1 fedora no fedora xp1 no xp1 win7 yes win7 xp1 no win7 fedora no fedora win7 no I can reproduce this behaviour every time I power cycle the router. It goes without saying that 30 minutes after resetting the router, neither xp1 nor win7 can access the samba exported printer on fedora, nor can fedora access the shares exported by win7 and xp1. I had called at&t - explained the problem. They sent a cable installer who knew nothing about administering the router, and he was candid enough to admit it. My only conclusion is that someone at at&t or a nearby is/are hacking our router, or the router's firmware is buggy. But I have never seen a bug like this that waits 20 to 30 minutes before striking :) -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
