In any case, if the green LED is completely off after you've sent your WiFi credentials, it means that the device has received the WiFi credentials you gave it, but either doesn't recognise them or something is preventing it from connecting to the Internet. Here are some hints as to why this particular problem may have occurred:
  • There is a spelling error in the WiFi name and password you entered.
  • The HAM device is not communicating with your router due to poor signal range.
  • Something is temporarily preventing your router from communicating with the Internet.
  • A complex security or operational setting on your router is preventing the device from communicating with the Internet.
Below are suggested ways to check if any of the above is happening, and ways to fix the problem.
Confirm your WiFi credentials
The first and simplest step you can take is to repeat the entire setup process from the beginning, re-entering your WiFi name and password to confirm that the information is correct. Even a 'blank' that you've accidentally left out can prevent the WiFi from communicating with the device.
Control the range of WiFi
Once you have ensured that your WiFi credentials are correct, it is possible that the HAM device may not be able to connect to the Internet due to weak signal range at the location where it is installed. Even if your mobile phone has sufficient signal at the location, there are several factors that can negatively affect the signal range to the HAM device (blind spots, objects, obstacles, etc.).
Checking your router's connection to the Internet
If you are absolutely sure that the above criteria are met and you have tried the device setup process again, but the green LED is still off, the next step is to make sure that your router is connected to the Internet.
Checking the security settings of your router
If you have made sure that your router is connected to the Internet and there are no connectivity problems, but the green LED is still off, then your router probably has some specific security settings that prevent the HAM device from communicating with the Internet. To illustrate, we will show you some of these settings that may be causing the problem, as well as ways to fix them.
  • Connect to the WiFi whose settings you want to check
  • Enter the login details for your account, which can be found on the back of your router.
  • In any browser, type the IP address displayed on your router into the search bar to access the router's settings page.

The first step after logging into your router's configuration page is to check that the HAM has received an IP address from the router. You can see how to test this by following the instructions in our related article by clicking here and following the test procedure up to step 3. The device should appear as HAMXX_XXXX, where XX_XXXX is the S/N of the device. If you don't see the device in the shared IP list, then the HAM device is not connected to your router, which means that:

1. Review steps 1 and 2 of this article: Check the accuracy of the data you are sending to the device and the range of your WiFi.

2. There is DHCP congestion: You can see how to check if there is a DHCP congestion problem and how to fix it by following the instructions in our related article.

3. You cannot find a 2.4GHz network.

If you see the device in the Distributed IP list, then the HAM device is connected to your router. In this case, check the rest of your router's security settings as shown below.

Firewal

To find out how to check if your WiFi router's firewall is blocking a HAM device from connecting to the Internet, and how to change this setting, follow the instructions in our article.

Access ports

You can find out how to check that the appropriate ports are open for HAM devices to communicate with the Internet, and how to troubleshoot any problems, by following the instructions in our article.

Limited list of devices
There is a less common setting, but one that is quite possible in business premises, that can prevent the HAM device from connecting to the Internet. This setting is called "Wireless MAC Filtering" and it is a device restricted access to the router, a kind of filtering of allowed devices based on their MAC address.
  • Then go to the Wireless MAC Filtering tab. You will see all the devices that have been given exclusive access by this setting.
  • Go to the 'Wireless' or 'WiFi' tab in your router's settings menu.
There are two ways to deal with the obstacles that Wireless MAC Filtering can pose:
  • You can disable the "Wireless MAC Filtering" filtering process altogether by clicking on the "Disable" option.
  • Alternatively, if you want to keep the setting active, you can simply add the HAM device you want to configure to the list of allowed devices, along with the device's MAC address.
