MTU
MTU specifies the maximum size of packet that the router can transmit. MTU varies across
connection types. The default setting is recommended.
You can try to change the MTU when:

or Paypal websites).
− You cannot 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.)

internet with the account. In this case, you can use the Clone MAC Address function to clone the
MAC address of this computer to the WAN port of the router to achieve network sharing.
Click Restore Default MAC to restore the MAC address of WAN port to the factory settings.
Here are two scenarios to clone MAC address.
Scenario 1: the computer used to manage the router is the computer that used to access the
