I recently by accident flipped the breaker on my network equipment and it went through a power cycle. When everything came up my Internet connection was dead. The xfinity gateway was set for bridge mode and my firewall is using DHCP to acquire an IPv4 address. I called technical services which were unable to assist with troubleshooting the IP issue.
I verified I was sending out DHCP discovery packets from my ASA 5505 with no response from the xfinity DHCP server, I also plugged in my Mac Book with the same results.
It is frustrating I have to revert back to routed mode to operate. No one on the xfinity side had a clue as to why this workes and doesn't work at times and how to resolve.
Does anyone have any experience with this issue and know how to resolve?
