LAN to internet via upstream router works; WLAN does not

Hello all,

Hopefully missing something simple here...

Installed openwrt 21.02 on TP-Link Archer C7 AC1750.

Plugged WAN into upstream Ubiquiti Dream Machine.

Ubiquiti default is, so went through this: [OpenWrt Wiki] Troubleshooting Internet Connectivity

Actually, had to use ssh to make the change as the LuCl UI didn't seem to make the change stick.

uci set network.lan.ipaddr=""
uci commit 
/etc/init.d/network restart

The change was persisted in /etc/config/network:

config interface 'lan'
        option device 'br-lan'
        option proto 'static'
        option netmask ''
        option ip6assign '60'
        option ipaddr ''


  • PC w/ LAN connection to openwrt to dream machine to internet works fine. (that's the path I'm using to open this ticket - wifi on PC is off)
  • WLAN connections to openwrt do not connect to the internet. In fact, it doesn't seem like WLAN connected clients are cleanly connecting to openwrt at all.

Thanks in advance for any help.


Check if your wireless interface is bridged to br-lan
