So Saturday night I had to come into work for a little while and figured while no one was around that I’d update pfSense to 2.4.5 all went very well and I pacaked up and went home around 8pm.
Well this morning I get to work and think nothing of it but after a few users complaining about wifi I started investigation. After many hours of troubleshooting(rebooting, packet captures, loss of sanity) I’ve discovered that dhcp offers aren’t being sent back to clients on one of my ssid’s. What’s strange is that all wired devices work fine, and 3 out of the 4 ssid’s work just fine. The only network that doesn’t work is the vlan that the DHCP servers live in, which is the same vlan that the ssid belongs to.
I’m considering downgrading our box back to 2.4.4 to see if it corrects the behavior but wanted to get a little community feedback first.

Any ideas or suggestions are welcome.
