Router not assigning IP addresses with DHCP on wireless

Installing and Using OpenWrt Network and Wireless Configuration
1

When I plug in to the router via Ethernet I get ipv4 and v6 addresses, however I will not get assigned anything when I connect via WiFi.

I am not sure where to start here. I tried editing the share interfaces in the wireless section, but that didn't work either.

I solved my issue. I was assigning multiple interfaces to the WiFi interfaces, I should have only selected the LAN interface.

And you bridged WAN to LAN.

I think I am, but I'm not 100% sure. I have a modem and it is directly connected to my router.

Remove the Bridge interfaces check and choose eth1

As @LGA1150 pointed out, you shouldn't bridge WAN and LAN. That's incorrect and is a security threat.

Thanks for the advice. I will do that soon.

I'm not sure why it was the default setting though.

Does this look correct?

Also on a side note, how do I go about using IPv6? As far as I can tell it is enabled, but what really is wan6?

It is the wan interface responsible for IPv6. Check with ifstatus wan6 if it has acquired the settings from upstream.
