I've been running this router for quite a while without any issues, but recently, it started giving out DHCP addresses from a range that it isn't even configured with. I've got the LAN DHCP range configured for 192.168.1.10 - .50, but wifi clients are receiving 192.168.0.x IPs and show the gateway to be 192.168.0.1 and they don't have access to the LAN or internet. If I manually configured the clients to use IPs from the correct range, or I do static DHCP assignments using the correct range...
