A PLDT router is generally used as a device for sharing the internet connection across the Local Area Network. However, a PLDT router can also be connected as a secondary access point to extend the range of the wireless LAN or Wi-Fi of the primary router connected to the internet.
I recently moved from a PLDT Fibr Home internet subscription to a Globe At Home subscription. Since I don’t have any more use for the PLDT Fibr ONU router, I decided to experiment connecting it as a wireless access point. Fortunately, I was able to make it work. Now I have an access point located on the second floor of the house. I now have a strong Wi-Fi signal when I’m up there.
Turning a router into an access point is supposed to be an easy task. First, connect a LAN cable from the primary router to the secondary router to be used as an AP. Second, configure the AP to have an IP address consistent with the primary router. And lastly, configure the AP’s DHCP server so it doesn’t conflict with the existing primary DHCP server. That’s it. Supposedly.
NOT FOR PLDT FIBR ONU ROUTERS.
Configuring a PLDT router as an access point is a pain in the ***. Actually, simply configuring a PLDT router is tedious enough, not only for access point configuration. First of all, you need to deal with enabling the router’s web admin account. Also, you have to find a way to disable the router’s AP Isolation. This feature on PLDT ONU routers prevents the wireless clients from accessing other devices on the LAN. This will also prevent us from successfully forwarding the network traffic from the AP to the primary router which would serve as the AP’s gateway and DNS server.
In this tutorial, we will assume that we have an existing LAN or a Local Area Network. We have at least one computer connected to a previously configured primary router. It doesn’t matter if the computer is wired or wirelessly connected to the router, as long as the computer has an internet connection. Having an internet connection implies that we have a properly configured router.
We will also assume that the primary router is not a PLDT ONU router. We will use a PLDT ONU router (Model AN5506-04) only as a secondary router to be configured as an access point (AP). In case the primary router which is connected to the internet and the secondary router to be configured as an AP are both PLDT ONU routers, be aware that both routers have to have their AP Isolation feature disabled.
Step by Step Guide
Step 1 – Connect the two routers
Connect one end of a LAN ethernet cable to the primary router and connect the other end to the secondary router which will act as an access point. Use a Category 6 ethernet cable.
Step 2 – Change the IP address of the second router
For a step by step guide on how to change the IP address of a PLDT router, please see, How to Change the IP Address of PLDT Routers.
Step 3 – Configure the DHCP server
DHCP stands for Dynamic Host Configuration Protocol. A DHCP server may refer to the program called a DHCP service or a DHCP daemon. It may also refer to the computer running the said program.
Routers are actually full-pledged computers usually running a Linux operating system. One of the functions of a router is providing a DHCP server on the Local Area Network.
Any device (desktop PC, laptop, or smartphone) wishing to connect to a Local Area Network needs some information in order to successfully connect to the network. The connecting device has to configure its network interface to properly connect to the network. It needs the following information:
- What IP address the device will use which will serve as its host identification when communicating with other devices on the network.
- What is the IP address of the gateway computer, which is usually the router, so it knows where to send messages going out to the internet.
- What is the IP address of the DNS server or the computer that is queried for resolving URL addresses. That is, when you type www.google.com on your browser’s address bar, that URL has to be converted to an IP address like 220.127.116.11. It is the job of the DNS server to provide such a conversion.
The DHCP server is the one responsible for providing the mentioned information above. In other words, the DHCP server is dynamically configuring connecting hosts, hence the name, Dynamic Host Configuration Protocol.
DHCP Start IP and DHCP End IP – these two entries have to be changed so they do not overlap with the IP addresses being handed out by the DHCP server of the primary router.
DHCP Primary DNS – IP address of the primary router or google’s public DNS server (18.104.22.168 or 22.214.171.124).
DHCP Default Gateway – IP address of the primary router
