I use Windows 7. And I set entry of Gateway in ARP table is Static. But I set Mac's Gateway wrong and I can't use Internet. So I use command "arp -d" to delete ARP table, then I can use Internet. But if i restart my PC, I can't use Internet until use "arp -d" again.

Why that? and how can i fix this bug?

You created a permanent entry in the ARP table but your deletion is only temporary until next reboot. Replace the faulty entry with arp -s and the correct details. – BJ292 May 19 '12 at 12:05
