MTU (Maximum Transmission Unit) is the largest data packet transmitted by a network device.
When the connection type is PPPoE, the default MTU value is 1480. When the connection type is
the dynamic IP address or static IP address, the default MTU value is 1500. Do not change the
value unless necessary. If you need to, please refer to the following instructions.
To access the configuration page, log in to the web UI of the router, and navigate to

.
Change the MTU value
Generally, the default value is recommended. Try to change the MTU value when:
-
You cannot access some specific websites or encrypted websites (such as E-banking or Paypal
websites).
-
You cannot receive or send Emails or access an FTP or POP server.
You can try reducing the value of MTU gradually from 1500 until the problem is resolved (The
recommended range is 1400 to 1500).
