Not sure what I did to fix it but check these: Do you have a GATEWAY=192.168.1.1 in the /etc/sysconfig/network file? plus in the ifcfg-eth0 file make sure DEFROUTE=yes I actually have a GATEWAY line in this file too plus DNS1= and DNS2= and in case it wasn't obvious NM_CONTROLLED="no" After all this my network comes up about 29 times out of 30, randomly it doesn't and then I just "sudo service network restart" and all is well. Just fyi, I also find randomly that the gnome login list sometimes sorts alphabetically rather than the default of by UID, no major difficulty but I am sure this kind of randomness is a fairly recent occurrence. > > So, if anyone has any good guesses on what the heck happened here, I'd > like to hear them. > > thanks in advance! >
