i recently install the latest openwrt firmware LuCI openwrt-21.02 branch](https://github.com/openwrt/luci) and setup the tp-link tl-wr1043nd v2.1 as access point, when it works, it's ok, but I'm noticed that after reboot my router, I'm losing internet access on all interfaces, i try to solve the issue on my own by search this forum and change the DNS server address on lan/wan , try to factory default and setup again, no luck
that's weird bug, I will happy to solve this issue as soon as possible, and want to schedule a monthly reboot but not sure i understand how
Might be due to a full flash memory, and overlay getting put into ramdisk (which naturally gets wiped at reboot).
check the system log for "overlay" and "jffs2" messages.
