I have been using P1 Wimax since August 2009. Personally, it is the best Internet broadband that we have in Malaysia. For Home Plus package, the average connection speed is around 120kbps-170kbps. But there were a few times where the speed dropped to 20-50kbps, and even sometimes it disconnected abruptly.

The purpose I write this post is to help you to secure your P1 Wimax WiFi modem. It is actually very easy for unauthorized users to gain access into your P1 Wimax network if you did not change the modem default password, WEP key, and Access Control List. In this How-To guide, I will show you the step by step on how to secure your P1 Wimax WiFi modem. Let’s begin…

Change the default password

Change P1 Wimax modem default password

By default, the username and password for P1 Wimax modem is,

Username: admin
Password: admin123

Please change the default password before someone else gain access to your modem and change it for you. To do that,

1. Go to http://10.1.1.254 by using your favourite web browser.
2. Enter the default username, admin, and password, admin123.
3. Click on Personalization at the top left of the page.
4. Enter your Old Password, admin123, and New Password.
5. Click Apply.

If you’ve changed the P1 Wimax modem password previously and forgot the password, you can reset it back.

After you have changed the default password, you also need to change P1 Wimax WiFi WEP key IF you are using DV230 modem. The modem is look like this,

P1 Wimax DV230 modem

As you may already know, by default P1 Wimax DV230 modem WiFi is using WEP key that is easy to guess. For an example, let’s say your P1 Wimax WiFi SSID is 056789. If the user didn’t change the default WEP key, the key is 567891FFB0.

SSID: 056789
Remove 0 at the front, 56789
Combine with 1FFB0, and your P1 Wimax WiFi WEP key is: 567891FFB0

To change the default WEP key,

1. Go to http://10.1.1.254 by using your favourite web browser.
2. Enter your username, admin, and password.
3. Click on Networking at the top right of the page.
4. Click on WIFI.
5. Click Next.
6. Under Use Default, choose User Defined.
7. And change the WEP key under Security Setting.
8. Click Apply.

Note: Please ensure to follow these rules to set your WEP key.

64 bit

• 5 ASCII characters (A-Z or a mixture of A-Z and 0-9)
• 10 Hexadecimal characters (0-9, A-F or mixture of both 0-9 & A-F only)

128 bit

• 13 ASCII characters (A-Z or a mixture of A-Z and 0-9)
• 26 Hexadecimal characters (0-9,A-F or mixture of both 0-9 & A-F only)

Only allow specific MAC addresses to connect

Only allow specific MAC addresses to connect into your WiFi network

Even though you have changed the default P1 Wimax WEP key, there might be some possibilities where someone can crack the WEP key and use your WiFi connection without your acknowledge. To prevent this, you can set your P1 Wimax WiFi modem to only allow specific MAC addresses to connect into your P1 Wimax WiFi network.

Let’s say your iPhone MAC address is F8:1E:DF:43:49:A9.

1. Go to http://10.1.1.254 using your favourite web browser.
2. Enter your username, admin, and password.
3. Click on Networking at the top right of the page.
4. Click on WIFI.
5. Click Next.
6. Scroll down to ACL-setting.
7. Choose Allow only following MAC addresses to connect to wireless network.
8. Under Access Control List, enter your device MAC address. Eg: F8:1E:DF:43:49:A9
9. Click Apply.

After the modem rebooted, only your iPhone can connect to your P1 Wimax WiFi network. Even though your neighbours can crack your WEP key but they can’t connect to your WiFi because their devices’ MAC addresses are not registered in the Access Control List.
