i took my macbook pro apart to regrease the chips (running hotter than should be). now, there seems to be issues with my firewall. i dont know if disconnecting the motherboard battery reset some nvram or something, but i am now having the following issues when the firewall is on: -ethernet/wireless will not connect, gives itself a 'self-assigned ip' of 169.---- -if i set ip/gateway/netmask/dns manually on ethernet/wireless it works -this is NOT a router issue as all the other computers on my network are using DHCP with no problem (AEBS) -other things such as printing to airport printer, accessing airdisk , dont work -if i disable firewall, everything works. -all my firewall settings hadn't changed. any suggestions? i'm having to leave my firewall off in the meantime. thanks!
