Change MTU value

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
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 choose System Settings >
WAN Settings.
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 and send Emails or access a 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).
