OPT Port Failover

Your SimpleWAN device supports failover to a secondary connection in the event your primary connection has an issue. You can easily add this feature by contacting your Reseller/support agent and asking them to activate the feature as it needs to be added at an administrative level.

Once the Failover feature is activated, update the new WAN2 interface with the failover connection IP info (static, DHCP, etc.). Once that new information is saved, power down the SimpleWAN, plug the secondary connection into the OPT port and then power the SimpleWAN back up so that it can run a speed test on the failover connection for QoS settings. Be sure to go into the Diagnostic Tools section, and then click speed tests to verify that both a WAN and a WAN2 speed test were run. If there is no WAN2 speed test result, verify that the WAN2 information was input correctly, and reboot the unit again.

It takes a minimum of 20 minutes for the connection to failback once it has failed over. This is to validate that the primary connection is once again stable and ready for use. The idea behind this is to verify that the connection won't just bounce back and forth between the connections and ensure that QoS is being maintained.

*If you are utilizing the failover feature of the SimpleWAN, we recommend that the primary connection is set to static. If it is set to DHCP, the device could have issues connecting back to the primary internet connection. Also, if the failover itself is taking a long to negotiate an IP address, set it to static as well to ensure a quick failover time.*

Other Uses For OPT Port

The OPT port may be used for dual WAN / teaming / balancing. It is only activated when the Load Balancing/Failover feature is active. Please choose the appropriate option under the WAN2 interface menu as shown below. As mentioned above, please verify that a speed test was run for both the WAN and WAN2 interface. YOU MUST USE OUR DHCP AND DNS SERVERS TO USE LOAD BALANCING.

The MiFi hotspot bridge option allows you to use an approved wifi dongle (please contact your Reseller/Distributor for pricing and model information) to connect the SimpleWAN device to a standalone MiFi hotspot. Simply go to the interface where you would like to set up the connection and choose hotspot bridge from the drop-down options. Then input the correct SSID (network name) and PSK (wifi password) in the fields below.

Things to watch out for: Settings on the MiFi device must allow it to remain on/active at all times (i.e. never goes into a sleep mode). The LAN IP on the Mifi must remain 192.168.1.1. The LAN IP of the SimpleWAN is recommended to be at 192.168.2.1.

4G Failover

SimpleWAN now supports 4G failover through Verizon, AT&T, and Sprint. We recommend that you use the Mifi option rather than using the 4g USB dongles because carriers are starting to restrict usability to these devices. The Mifi option gets around this limitation. You can contact your sales representative or SimpleWAN directly to inquire about adding this service. You Must be running Version 6.0.0. for 4G compatibility.

Verizon UML290:
When you have your 4G failover device, simply plug it into any USB port. You can use a USB cable to extend the length or place the antenna in a better position.

  1. Before installing the card and enabling failover on the unit
  2. Make sure the unit is upgraded to the latest firmware release
  3. When the second step is complete, install the USB device to the simple failover device
  4. Go to the site (SimpleWAN unit) through edit and “enable” Failover
  5. Go to the user dashboard in the “interface” menu and select 4G from the WAN2 selection
  6. Unit should auto-calibrate the secondary connection. When complete this can be confirmed under the speedtest field. Ex: WAN2 upload: 4.5Mbps download: 55Mbps.

*If you are having connectivity issues with the UML290, it is possible you need to change the IP mode of the device. This can be done by connecting the 4G device to a laptop, open the Verizon wireless manager panel. Once there you will need to do the following. Press Cntrl-D this will bring up a password text box, enter the password diagvzw. This will bring up another window of configuration settings. Set them as you see below.

Sprint 341u:

  1. Connect the device to a Windows computer
  2. Activate
  3. Go to settings and disable Auto connect (Set to Manual)
  4. Set to IP passthrough mode (Disable Nat/Router)
  5. Save all settings
  6. Set to 4G Sprint in SimpleWAN Dashboard for WAN or WAN2 (Follow Normal 4G Setup procedure from here)

AT&T 340u:

  1. Connect the device to a Windows computer
  2. Activate
  3. Run AC340U_Linux_Patch executable to put in IP passthrough mode. (Download here: ac340u_patch_v4.zip)
  4. Wait for the tool to complete.
  5. Set to 4G AT&T in SimpleWAN Dashboard for WAN or WAN2 (Follow Normal 4G Setup procedure from here).
  6. AT&T has made changes to the latest firmware upgrade for this device which removes all support for this. Please be sure to not upgrade those devices if you want to use them with the SimpleWAN device.

NOTE: On both Sprint and AT&T devices, even when they are connected in this IP Passthrough mode the display says “Ready to Connect”. After you apply Failover, you'll need to reboot your SimpleWAN Appliance. If you do not see the speed test results on WAN2 after 10 mins please reboot the unit to initialize a speed test on both the primary and secondary connections. Double check or repeat the steps above if needed.

NOTE: When using failover, you need to use external DNS servers Like Google otherwise failover won't kick on.

Check 4G Signal Strength
From the unit's control panel page, you will see a box for the signal strength of your 4g card. the response can be slow as the box will run a strength test then upload it, allow 3-5 minutes for a response.

Setup 4G as the Primary Connection

  1. Activate the correct supported card on a computer and connect to the Internet. Make sure the firmware is up to date and you can get online.
  2. Test on the computer for signal where the device will be installed.
  3. Plug in the SimpleWAN box in a wired connection and make sure it talks to the dashboard and downloads all of its settings.
  4. Install the wireless device on the SimpleWAN box.
  5. Change the WAN settings in the dashboard to the property 4G WAN.
  6. Verify the sync time shows it sanc in the dashboard.
  7. Reboot the box
