Re: DHCP not working when we lose our ISP
Just curious if when the Internet goes out, is the Windstream gateway device still connected? Have you logged into it to see what the status say about the connection?
We have some sites on a sat modem connections (that are on a private 10. or 100. IP address) that if there is any communicate or cabling issues the modem device defaults to handing out 192.168.x.x IPs to any CPE connected to it. Not by choice that some of our remote managed sites are using the same 192 IP subnet as common retail routers, but what is more of an issue for us is this Sat ISP provider set the default DNS IP to 192.168.0.1. thus forcing the the fgt to disable the LAN interface because it has matching IP (conflict). (Sadly these sat modem devices are NAT only devices with no way to allow/set bridging.)
