I have a old "ADSL 4-port wireless modem router" laying around and I wondering could I convert it into WLAN Access Point. Is is possible for Wireless router unit with built-in modem? so far I not able to find much information on web.

My model is TP-Link TD-W8961ND

Yes. Simply disable NAT and DHCP service. You want it to be just a bridge, with wireless AP mode on.

Use one of the LAN Ethernet ports to connect it into your home LAN (e.g. into a LAN port of your upstream router).

work nicely after DHCP service is off on the AP router, NAT on and off so far no noticeable difference – Dennis Sep 16 '13 at 14:42
so you have to manually assign all IPs? Isn't possible to leave the dhcp services on? Or how can I provide another shcp service? – Felice Pollano May 5 at 15:34
@FelicePollano OP wanted his device to just bridge traffic between wireless clients and the rest of his LAN. He would have had another device on the LAN acting as a DHCP server and NAT gateway. Most people should avoid having multiple NATs and DHCP servers on their networks. – Spiff May 5 at 15:59

Yes it is a wireless router with built-in ADSL modem, just like our Wireless ADSL router (, and sure it can work as a AP no problem.

You could setup an access point by following these steps :

1-Find the IP addresses of your existing gateway/router and clients : connect a pc to it and use (Start > Run > type: cmd) ipconfig to get its IP (gatway ip). don't forget to - set your client computer to obtain its IP automatically (default behavior in Windows)

enter image description here

2-Configure the wireless router/AP First, you need to change its internal/LAN IP address to an unused address in the same range/subnet as all your other LAN devices to avoid any collisions. Second, you need to disable the DHCP server on your new AP, so there is only one DHCP server on the network. for exemple if the gateway/LAN router ip is set to, and it is serving dynamic IPs via DHCP in the range - I have to use any other address in the 192.168.1.X>100 range for the access point.

3-Connect the AP to the LAN first reboot the router and Use a LAN port on the new wireless router, and connect it with a network cable to one of the LAN ports of the existing gateway. Make sure not to use the "Internet/WAN" port on the wireless access point!

4-conenct your wireless device and test

Notes: If both your main gateway and access point have wireless capability, you can use the same SSID, same security, and different non-overlapping wireless channels to extend the range of your wireless network and allow clients to connect to either one automatically.
