Hi,
This issue we are resolved and will update the codes.
Please try these commands in the SSH of router to temporary use:
mkdir -p /usr/share/nftables.d/chain-pre/mangle_prerouting
echo 'iifname wlan-sta0 counter ip ttl set 64' > /usr/share/nftables.d/chain-pre/mangle_prerouting/01-set-ttl-portal.nft
/etc/init.d/firewall reload
If the above operation still doesn't work, please execute the following command after repeater connected.
iptables -t mangle -A PREROUTING -i wlan-sta0 -j TTL --ttl-set 64
Some uses nft as the firewall feature, and some are iptables. In addition, different models, different band, relay interface name is also different, so it is not easy to provide temporary commands. Please wait for our new firmware if you cannot use the SSH debugging.
