Multy WiFi System User’s Guide
195
• Make sure traffic between WiFi and the LAN is not blocked by the firewall on the Multy Device.
• Make sure you allow the Multy Device to be remotely accessed through the WLAN interface. Check
your remote management settings.
The WiFi connection is slow or 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 WiFi devices.
To optimize the speed and quality of your WiFi connection, you can:
• Move your WiFi device closer to the Multy Device if the signal strength is low.
• Reduce WiFi interference that may be caused by other WiFi networks or surrounding wireless
electronics such as cordless phones.
• Place the Multy Device where there are minimum obstacles (such as walls and ceilings) between the
Multy Device and the WiFi client. Avoid placing the Multy Device inside any type of box that might
block WiFi signals.
• Reduce the number of WiFi clients connecting to the same Multy Device simultaneously, or add
additional Multy Devices if necessary.
• Try closing some programs that use the Internet, especially peer-to-peer applications. If the WiFi client
is sending or receiving a lot of information, it may have too many programs open that use the
Internet.
• Position the antennas for best reception. If the Multy Device is placed on a table or floor, point the
antennas upwards. If the Multy Device is placed at a high position, point the antennas downwards.
Try pointing the antennas in different directions and check which provides the strongest signal to the
WiFi clients.
9.7 OpenVPN Problems
Client devices cannot connect to the Multy Device server.
• Make sure the Multy Device is in standard (router) mode.
• Make sure DDNS is enabled in the
Settings > Internet > Dynamic DNS screen.
• Make sure the OpenVPN Server account is enabled in the OpenVPN Server > OpenVPN Server screen.
• Make sure Advertise DNS to Clients is enabled in OpenVPN Server > OpenVPN Server screen.
• Make sure the VPN client is using a reliable Internet connection.
• Make sure the VPN client is using the correct protocol (TCP/UDP) to connect to the OpenVPN Server.
• Make sure the client connecting to the OpenVPN Server account is using the same port number
(default server port number is 1194) to access the server account.
