Wireless Connectivity

Troubleshooting a StrideLinx router with 4G or WiFi is best accomplished as follows.
1. The WiFi connection SSID must be alphanumeric; it cannot include special characters,
such as hyphen, apostrophe, etc.
2. 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.
3. 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.

StrideLinx™ Cloud 2.0 Industrial VPN Routers User Manual
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.
Clear line of sight between the router antenna and the wireless access point will
provide a better connection.
(4G) If a single antenna is used, ensure the antenna is connected to the MAIN
antenna connector, nearer to the front of the router. If a single antenna is connected
properly to the MAIN connector, add a second antenna to the DIV connector.
(WiFi) check to make sure the SSID and password are correct.
(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.
(4G) Make sure your cellular 4G SIM card is activated by the carrier.
(WiFi) Open WiFi settings and confirm wireless access point signal strength and
SSID, password.
(4G) On an AT&T smartphone, look in the upper left hand corner to determine
network signal strength.
Verify that the monthly 4G data limit has not been exceeded.
Verify that the correct certified device type (i.e., IXON StrideLinx VPN Router 4G)
has been selected for use with the SIM card.
Use AT&T's diagnostics feature to check for other issues with the data plan.
