“ HTTP/VNC/Data Logging services and shortcuts ” section of Chapter 2 explains how you can
add or manage these services.
Specific Service and Server Settings
A VNC server running on certain devices may require advanced settings, such as encoding type
or color depth. You can configure these settings by clicking SHOW MORE in the top right
corner when configuring a service.
If you have a VNC server running on a computer, make sure you VNC server’s encryption
setting, if available, to also accept unencrypted connections.
Wireless Connectivity
Troubleshooting a SiteLink router with 4G or WiFi is best accomplished as follows.
1. Be sure the issue is WAN connectivity - The ACT LED will be blinking red 1 time for no
internet connectivity. If the ACT LED is anything other than blinking red 1 time, then
the issue is not wireless connectivity.
2. Check the Signal LED to determine if the router has a good signal. If not, check to make
sure the antenna connectors are properly screwed on to the router and that the cable is not
twisted, pinched, or damaged.
a. Observe the area around the antenna installation. The magnetic and screw mount
antennas work best when connected to a metal ground plane at least 30 cm². In
addition, metal located above or on the sides of the antenna will decrease the range.
b. Clear line of sight between the router antenna and the wireless access point will
provide a better connection.
3. If a good signal is shown (purple or blue) on the Signal LED, then
a. (WiFi) check to make sure the SSID and password are correct.
b. (4G) check to make sure the SIM card is properly inserted into the router and that the
APN and PIN code have been correctly entered.
4. As a double check, use a smartphone at the router location to check the signal strength.
a. (WiFi) Open WiFi settings and confirm wireless access point signal strength and
SSID, password.
b. (4G) On an AT&T smartphone, look in the upper left hand corner to determine
network signal strength.
If your smartphone shows a signal the wireless connection to the router should also be
adequate.
5. For the 4G router, diagnose issues with the data plan or SIM card using AT&T’s web site
at https://marketplace.att.com/data-plans .
a. Verify that the monthly 4G data limit has not been exceeded.
b. Verify that the correct certified device type (i.e., IXON SiteLink VPN Router 4G) has
been selected for use with the SIM card.
c. Use AT&T’s diagnostics feature to check for other issues with the data plan.
