I followed this guide: https://stantsui.blogspot.com/2015/09/tp-link-mr3220-v1-upgrade-to-dd-wrt-and.html

For the first time, it worked for 2 days, than it dropped the network and I still can't set it up to receive the Wi-Fi signal and share it through its LAN ports. I have the main modem which is not broadcasting the signal, instead, I have n old UniFi AP which is working perfectly.

I installed DD-WRT on this TP-Link router successfully, and I set these settings:
WAN connection type: Disabled
Local IP Address: 192.168.0.4 (0.2 is the AP, 0.1 is the main modem, 0.3 is another server)
Subnet mask: 255.255.255.0
Geteway: 192.168.0.1
Local DNS: 192.168.0.1
Assigned the WAN port to Switch
Turned DHCP Server off

Changed operating mode to Router in Advanced Routing

In Wireless settings
Wireless mode: Client Bridge (Routed)
Default GW Mode: Tried Auto(DHCP) and Manual
Wireless Network Mode: Mixed
Channel Width: Full (20MHz)
SSID: The name of the Wi-Fi signal
I set the password with the security mode, too.

And finally, I disabled the SPI Firewall.

As I disabled the DHCP server, I don't get IP address, only like 169.xxx.xxx.xx
I have to manually select one to even connect to the TP-Link

I set to Factory Defaults multiple times and started all over again without any luck.
I also tried to follow other guides like DD-WRT's own Client Bridge video but still nothing.

Can someone help me to get this thing working again?
