I have a fiber modem connected in bridge mode to rpi4 with wan has the on board port and lan as usb rtl582 dongle.
It seems if i reboot the rpi4 it will take 45-60 mins to get internet connectivty. I can see on reboot it grabs a new IP and does not re-use the same assigned wan ip, but the routing is not working untill 45-60 mins or i reboot the modem.
On reboot if I can keep the same IP that was set for wan then i wont have the routing issue. My ip before switching routers (ubiqiti edge router) to openwrt 21.02 has not changed in almost a year and router reboots routed traffic right away on start up.
Any idea to get openwrt to keep/try reuse the wan ip it was assigned?
