DG1670 + TL-WA801ND Access Point Issue - Time Warner Internet

This question is about "DG1670 + TL-WA801ND Access Point Issue", with Time Warner Cable internet and apps. Hello all, I've been having trouble getting my TPLink access point to work. I can't access the DG1670 so I've been having to guess it's DHCP range. I used ipconfig to get the subnet and gateway address and i've tried assigning a static ip similar to my pc's, but after saving the settings and rebooting I can no longer connect back to the access point. I'm using my phone's wifi to log in, and it fails to connect after trying to obtain an ip address. At this point I'm not quite sure what to do.

Is the DG1670 even compatible with access points?
