Hello everyone,
I am just getting started with using OpenWrt on an old TP-LINK Archer C7 v2 device. Last few days were challenging had to do a lot of forum browsing to fix issues and for now i have a stable PPPoe with my fiber modem also wireless clients have no issues. Wired clients are not able to get an IP address nor they can reach the gateway if i configure the IP address manually.
I have enabled debug on dhcp and watching the logs from /tmp/dnsmasq.log and i see no requests coming in from wired client (android tv box), i connected my laptop and tested the same as well.
Model: TP-Link Archer C7 v2
Firmware Version: OpenWrt 19.07.3 r11063-85e04e9f46 / LuCI openwrt-19.07 branch git-20.197.49655-210b489

Most of the configuration is default except for a new vlan for tagging for the wan connection. Thanks in advance, looking forward to hear from the experts
