If you ever have to complete a factory reset on your modem, you'll need to complete these steps to ensure that your modem's settings and DSL service are as secure as possible.
Enter 192.168.1.1 into any web browser, click enter, and the page below will appear.
It is very important to erase the pre-populated password and enter 1234 into the field manually.
If you do not erase and enter manually, you will not be able to make any changes to the settings within the modem:
On the next page, click "Ignore":
Click on the radio button "Go to Advanced setup", then click "Apply":
On all of the following steps, it is critical that you click Apply after every change.
On the tree on the left hand side of the page, click on "Advanced", then "Remote MGMT".
Click on the "SNMP" tab, then click on the drop down menu to the right of "Access Status", choose "Disable".
Again, it is critical to click "Apply":
On the same tree on the left hand side of the page - "Advanced"-->"Remote MGMT".
Click on the "DNS" tab at the top of the page.
To the right of "Access Status", click on the drop down and choose "Disable".
Again, it is imperative to click "Apply" after this and all steps:
Click on the "Network" tree on the left hand side of the screen, then click "LAN".
On the top tab, click on "DHCP Setup"
Under "DNS Server", the default settings will show the Primary and Secondary DNS Servers as 0.0.0.0.
Change the "Primary DNS Server" to 18.104.22.168 and change the "Secondary DNS Server" to 22.214.171.124
Again, it is critical to click Apply when finished changing these settings.
Before the next step, it would be wise to ensure that you did all three steps properly by going back through and checking your work thus far.
On the the Advanced-->Remote MGMT tab, both DNS and SNMP should be set to Disabled.
On the Network-->LAN tab, DHCP Setup should show the Primary and Secondary servers as 126.96.36.199 and 188.8.131.52.
After you've checked your work, you're ready for the next step.
For MAC users, click on the Apple insignia on the upper left hand corner of the screen, then click "System Preferences":
Click on "Network"
Highlight the network you're using for your service by clicking on it, then click on "Advanced":
Make sure the "TCP/IP" tab is selected/highlighted, then click on "Renew DHCP Lease".
Then click "OK":
You might get a warning message that says that any unsaved changes may be lost. Click "Apply":
Congratulations! Your ZyXEL modem configuration changes are now completed!!!
