TP-Link Archer C20 v4 soft reset after reboot using wpad mesh openssl

Installing and Using OpenWrt
1

I have two ั20 and they both have the same issue.If i choose wpad mesh openssl instead of wpad-basic-mbedtls when i customize installed packages(firmware-selector.openwrt.org) i get soft reset after reboot.I manage to connect to my mesh network and everything works fine.But after power loss or reboot i get default settings.What can i do to solve this problem?

Youโ€™re likely out of space.

ubus call system board
df -h

Usually 1MB+ openssl does not fit in 1-2MB space on 8MB device. Try wpad-mbedtls (you need wpad package with both - supplicant and hostap in mesh) which works on top of pre-supplied crypto framework.

Thank you!I really ran out of space/ I had these additional packages in my firmware-customizer:

iptables-mod-extra iptables-mod-nfqueue iptables-mod-filter iptables-mod-ipopt iptables-mod-conntrack-extra ipset curl

After leaving only wpad mesh openssl i dont have the issue anymore.

Get rid of iptables, nft needs only kmods in addition to cli tool
