DHCP Issues with RT3200

Installing and Using OpenWrt Network and Wireless Configuration
1

I have a RT3200 made by Belkin and I have it setup to act as an AP. The issue is no clients can get IP addresses from my main firewall. It is on the same LAN as the LAN of the AP, so I am not sure what is happening. I disabled dnsmasq, firewall and odhcpd and still nothing. If I set the LAN of the AP to DHCP, it does get an IP, but wireless clients do not.

There may be another issue or the root. I gave the tablet a static IP and it cannot access anything on the network.

Change option device 'lan1' to option device 'br-lan' and restart the network service.

I did do a default reset and it is working now. My download speed is better, but upload is still below 200, any ideas?
