Wan Settings - Tenda AC15 User Manual

WAN Settings

Log in to the Router's User Interface, and click Administration > WAN Settings.
MTU
Do not change the default value unless necessary. If you are unable to open some website, to receive
or send emails, etc., try to minimize the MTU value until your network returns to normal.
MTU Applications
1500 Typical for connections that do not use PPPoE or VPN
1492 Used in PPPoE environments.
1472 Maximum size to use for pinging. (Larger packets are fragmented.)
1468 Used in some DHCP environments.
1436 Used in PPTP environments or with VPN.
Tips
An incorrect MTU setting can cause Internet communication problems. You might not be able to
access certain websites, secure login pages, or FTP or POP servers.
WAN Speed
By default, the WAN rate is Auto. Generally, it is not advisable to change the default value. When
the cable length between your Router and the remote device (modem, Router, etc.) is relatively long,
you can set WAN rate to 10M or 100M to enhance transmission rate.
