This is how to block particular MAC address from connecting to your PLDT HOMEDSL WIFI or modem.
The internet speed of our PLDT WIFI modem became so slow that I had to again check if there are unauthorized connections. A couple of months back, I had to change the name and password of our PLDT WIFI following these steps to stop leechers and ISP hackers from connecting to our modem.
At that time, I suspected that our PLDT modem was hacked hence, the unauthorized connections, which resulted to turtle-speed. Things got back to normal after I successfully accessed PLDT admin and updated our HomeDSL name and password.
Today, when I checked the Active Clients list, I can see one unauthorized MAC Address so I googled for ways on how to block the MAC address of this gadget so it will not be able to connect again to our WIFI. These are steps, in case you want to also block certain MAC addresses from connecting to your PLDT WIFI modem.
How to Block PLDT HOMEDSL WIFI Users through MAC Address
First step, you need to login to PLDT WIFI admin page. Go to http://192.168.1.1/ Use these credentials to access PLDT Admin.
Second step, on the navigation bar click on “SETUP” then “WLAN” then “BASIC” and finally, click on “SHOW ACTIVE CLIENTS”.
This way you scan the list of active clients and will be able to identify if there are MAC addresses that you don’t recognize from the list.
We are a three-person-household with 3 laptops, 3 smart phones, and 1 tablet. We have a list of our MAC Addresses for our reference.
This is a sample table of ACTIVE WIRELESS CLIENTS currently using our PLDT HomeDSL
Earlier, I saw one MAC Address using our wifi access that I know does not belong to us, therefore, it’s connecting without authorization. I decided to block it.
Third step, Once you have identified the MAC address that you want to block, go back to WLAN settings. Then click “Access Control List”. Check our screenshot guide.
The Wireless Access Control page will load. In here, you can now select the setting that you prefer, there are 3 options:
- Disable – choose this if you want things as in, i.e. no blocking, no specified allowed users
- Deny Listed – choose this if you want to prevent access by identified MAC address.
- Allow Listed – choose this if you will allow certain gadgets to connect to your wifi.
From PLDT “If you choose ‘Allowed Listed’, only those clients whose wireless MAC addresses are in the access control list will be able to connect to your Access Point. When ‘Deny Listed’ is selected, these wireless clients on the list will not be able to connect the Access Point.”
For our blocking purposes, I’ve chosen the “Deny Listed” option.
Fourth step, Select the option you prefer, and then click on “Apply Changes”. Wait for about 15 seconds for the Wireless modem to update the settings.
Fifth step, on the MAC Address field enter the MAC Address you want to block; again you can get this from the List of Active Wireless Clients.
Enter the MAC Address without the “:” in between numbers.
If you will enter with the colon in between digits, it will error when you click “add”.
Sixth step, After correctly entering the MAC address that you want to block, click “Add”.
Wait for about 15 to 20 seconds again for the WLAN settings to refresh. Once done, the page will load and you can see the successfully blocked MAC address under the Current Access Control List.
MAC ADDRESS BLOCKING VALIDATION
To confirm that you have successfully block unauthorized gadgets from connecting to your WIFI, go back to the Active Wireless Client Table; if you did things right, you won’t be seeing the MAC address you’ve just blocked.
Now, just in case you mistakenly blocked a MAC address, you can reverse it simply by going back to the Wireless Account Control page, scroll down to “current access control list”. Then click “Select” beside the MAC address you want to unblock, then click the “Delete Selected” button. The page will again refresh for a few second to update settings. The blocked MAC will be unblocked.
Finally, Don’t forget to save the new configurations of your PLDT modem by going to the main dashboard and clicking “SAVE” in the sidebar where it says “Attention config is modified to make it effective forever save’.
You need to do this ‘saving’ if you change or update any settings for your PLDT WIFI.
If you fail to do this, the setting will revert back to its old setup after you turn-off your wifi modem. So save at root level. All is well from then on!
Hope this blocking MAC address tutorial guide helps you!
