Internet lose access after reboot (tp-link tl-wr1043nd v2.1)

i recently install the latest openwrt firmware LuCI openwrt-21.02 branch]( 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.

i think that you right, so it's hardware limination if I understand

Those look actually as expected. So, my guess might be wrong.
What does "df -h" show to you? A normal overlay at a mtdblock?

(The generic answer might still be hardware limitations, but the detailed reason might be something else than I first thought)

Does system log offer any clues?

I'm posted link to full log files, maybe it will help us because I don't know how to figure out

At the first glance, those logs looks pretty normal to me.
No hints from them :frowning:

so what you suggest?
