WAN DHCP not renewing lease/establishing w/o intervention after reboot/shutdown
-
Not sure when or why this started happening but after I reboot or shutdown the pfSense box I have no internet until I manually click. What settings/logs would you need me to provide to help diagnose. I have disabled all extra services and that didn't make a difference (snort, squid, pfblockerng, watchdog) I have tried several different settings under the advanced configuration for WAN DHCP. (pfSense default, FreeBSD default, blank, with and without reject leases) as soon as I hit the "renew" button the link comes up. If I make a change to the protocol timing settings after pfSense has come back online and save the IP gets renewed and the link is established also.
below is from DHCP log after I cleared it and rebooted. I let it sit for a few minutes before I hit the renew button. I also removed items relating to other DHCP scopes for different VLANS. Which I have also disabled for trouble shooting but didn't make a difference.

Curious- who is your ISP? What kind of interface is your WAN?

isp: charter
baremetal
wan: not a VLAN, physical intel nic connected to a motorola surfboard cable modem (is that what you are asking?)reading the other threads posted and will come back and post any relevant info

i think i resolved it
replaced cable modem and WAN nic (think modem was the issue though)
it was showing a connection at 100Mbps even when connected directly to laptop. used to be 1000mbps - i noticed it a while back after we had a storm but didnt think anything of it
now connected at 1000Mbps and connection has come back online after a couple reboots and shutdowns
does that make sense? wasn't having issues with connection except for dhcp issue

Yep- total sense. Thanks!
