WE826-q with EP06, internet on wired laptop, no internet when connected to wifi and no internet passing through to mesh wireless network

I'm running openWRT on we826-q with EP06 on visible network. I am connected to LTE fine and can access internet when I have laptop connected to LAN1, but I get no internet when connected to the WE826's wifi. Also, no internet on my mesh wifi network when LAN1 is connected to my main router via LAN. I'm sure I'm doing something incredibly ignorant here, but looking for any direction on what these symptoms may indicate.

Thanks in advance..

Make sure the LAN and WAN do not have the same network numbering. If so, renumber LAN.
