Auto-negotiation.
MAC Address
It is used to clone the MAC address accessible to the internet to the WAN port of the
router. If the router cannot access the internet after you configure the internet settings, it
is perhaps that the ISP has bound the connection information with a MAC address. In this
case, you can try to clone the MAC address, and try to access the internet again.
- Default: It is used to restore the MAC address of the WAN port of the router to factory
settings.
- Clone local MAC address: It is used to set the MAC address of the WAN port to the
MAC address of the current device managing the router.
- Set MAC address: It is used to set the MAC address of the WAN port manually.
12.3.2 Changing MTU value
You are recommended to retain the default value of MTU, unless the following cases happen:
 Websites are inaccessible, or you cannot log in to some secure websites (such as paypal login page).
 Email service fails, or FTP, POP and other servers are inaccessible.
In these cases, you can try to decrease the MTU value from the maximum one (recommended range: 1400-1500),
till the problem is resolved.

12.3.3 Changing the MAC address of the WAN port
Ensure that the MAC address to be cloned is correct! Before you have AC10/AC10U, the MAC address of
your computer that can access to the internet through the Ethernet jack, or the WAN MAC address of
your original router that can access to the internet, is the correct MAC address you should clone.
1. To access the configuration page, click System Settings > WAN Settings.
2. MAC Address: Select Clone local MAC address or Set MAC address from the drop down list box. If you
select Set MAC address, enter the MAC address that you want to clone. If you select Clone local MAC
address, configure this function on the computer with a correct MAC address.
3. Click Save.
