I have an EdgeRouter Lite recently updated to 1.9. It is configured very basically with some port forwarding for PS4 traffic and 2 VLANs. Primary for my internal home network and secondary for my work from home ASA. The eth0 is connected to my Google Fiber router and gets a 10. IP which is configured to be reserved from the GF router. There is also a couple of Unifi APs connected through a NetGear Gigabit switch. 90% of the traffic is Wifi traffic in my house.
The problem is that regularly, 2 sometimes 3 times a week the DHCP is lost on the eth0(WAN) port on the Edge router. I log in, bounce the eth0 port and then all is good for a few days. This has been happening for quite some time, and generally, I have just dealt with the issue. It even happened when I had TW as a provider so I know it is not specifically related to the ISP.
If anyone has any ideas please share. It is not an urgent issue, but definitely annoying.
