I cannot connect to the Internet using an Ethernet connection.
1 Make sure you have the Ethernet WAN port connected to a MODEM or Router.
2 Make sure you configured a proper Ethernet WAN interface (Network Setting > Broadband screen) with
the Internet account information provided by your ISP and that it is enabled.
3 Check that the WAN interface you are connected to is in the same interface group as the Ethernet
connection (Network Setting > Interface Group).
4 If you set up a WAN connection using bridging service, make sure you turn off the DHCP feature in the
Network Setting > Home Networking > LAN Setup screen to have the clients get WAN IP addresses
directly from your ISP’s DHCP server.
32.5 WiFi Problems
The WiFi connection is slow and intermittent.
The following factors may cause interference:
• Obstacles: walls, ceilings, furniture, and so on.
• Building Materials: metal doors, aluminum studs.
• Electrical devices: microwaves, monitors, electric motors, cordless phones, and other wireless devices.
To optimize the speed and quality of your wireless connection, you can:
• Move your wireless device closer to the AP if the signal strength is low.
• Reduce wireless interference that may be caused by other wireless networks or surrounding wireless
electronics such as cordless phones.
• Place the AP where there are minimum obstacles (such as walls and ceilings) between the AP and
the wireless client.
• Reduce the number of wireless clients connecting to the same AP simultaneously, or add additional
APs if necessary.
• Try closing some programs that use the Internet, especially peer-to-peer applications. If the wireless
client is sending or receiving a lot of information, it may have too many programs open that use the
Internet.
