wireless networking - AirRouter wired connections working, AP is not

I recently added a Ubiquiti AirRouter to my network. (Let's call this AR) It is wired to my TP-Link router (Let's call this TP) which is wired to my modem.

TP is my DHCP server. Wired clients to AR are reflected in the TP clients list, and can access the internet. They do receive an ip within the TP DHCP range (192.168.4.1 to 192.168.4.254). Wireless clients, according to their ipconfig and the AR clients list, attempt to use a 169.x address.

These are the AR settings:

These are the TP settings:

ipconfig for a wired connection to either device looks like this:

ipconfig for a wireless connection to AR looks like this:

I can post more of the settings or anything else needed to figure this out. Thank you!

Answer

Judging from the Ubiquiti AirRouter User Guide, you almost certainly have AR in "Router" or "SOHO Router" mode, when you need it to be in "Bridge" mode.

Note that disabling NAT does not enable Bridge mode. Disabling NAT just makes it a traditional IP router (routing between two IP subnets without translating/masquerading IP addresses).

Switch it to Bridge mode and it should work the way you want.
