I installed my PFSense box about a month ago, and the set up is:
Cable Modem (bridge mode) > PFSense (running DHCP server > Linksys Router running DD WRT as an Access Point > every device in my home, both wired and wireless.
The problem I'm having is that the internet connection on my Linksys DD WRT box will die for about 30 seconds, a few times a day randomly. I think the router is rebooting, since the WiFi signal stops. And on my laptop, I can't find the router for about 30 seconds, and then it reappears and everything is fine.
I'm not sure where to start looking for the cause of this, but I've owned the router for over a year and it's been solid until I disabled DHCP, converted it to be an AP only, and added the PFSense box between it and the cable modem. So I assume something about the PFSense box, or the configuration changes I made to the router are to blame.
It could also be the PFsense box itself is rebooting or dropping internet connection although I doubt it, because it seems like the router itself has the WiFi die during this time. If the PFsense box was to blame for the dropped connection, I'd expect WiFi to still be on, but lose access to internet.
Any thoughts?
