Unable to adjust HAM RemoteAC the green LED is not lit

Last Update 2 years ago

If, during device setup, the green LED is completely off after you've entered your WiFi credentials, it indicates that the device has received the information but is having trouble recognizing it or is unable to connect to the Internet. Here are some possible reasons for this issue:
  1. There is a spelling mistake in the name and password of the WiFi you entered
  2. The HAM device is not communicating with your router due to poor signal range
  3. Something is temporarily preventing your router from communicating with the internet
  4. A complex security or operational setting on your router is preventing the device from communicating with the internet
Below are suggested ways in which you can check if any of the above is happening, as well as ways to correct the problem.
Confirm your WiFi credentials
The first and simplest step you can take is to start the setup process from the beginning. Re-enter the WiFi name and password, ensuring that the information is correct. Even a blank space or a small error can prevent the WiFi from communicating with the device.
Control the range of WiFi
As long as you have verified that your WiFi credentials are correct, the HAM device may still struggle to connect to the internet due to a weak signal in its installed location. Even if your mobile phone shows a strong signal in that area, various factors can hinder the signal range to the HAM device, such as blind spots, physical objects, or obstacles.
Check the security settings of your router
If you've confirmed that your router is connected to the Internet without any issues, but the green LED is still off, your router may have specific security settings that are preventing the HAM device from communicating with the Internet. Below, we will outline some of these settings that could be causing the problem, along with solutions to resolve it.
  • Connect to the WiFi whose settings you want to check
  • Fill in your account login details, which are indicated on the back of your router
  • In any browser, type the IP address indicated on your router in the search bar to be taken to the router's settings page
After logging into your router's configuration page, the first step is to check whether the HAM device has received an IP address. To find out how to do this, please follow the instructions in our related article by clicking here, and continue the testing procedure up to step 3. The device should appear as HAMXX_XXXX, where XX_XXXX represents the device's serial number. If you don't see the device listed in the assigned IP addresses, it means that the HAM device is not connected to your router. This indicates that:

1. You should review steps 1 and 2 of this article: Re-check the correctness of the data you are passing to the device and the range of your WiFi.

2. There is DHCP Overload: You can see how to check if there is any DHCP overload problem and troubleshoot it by following the instructions, in our related article.

3. Unable to 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, proceed to examine the remaining security settings of your router as shown below:
Firewall Protection

You can see how to check if the Firewall of your WiFi router is blocking the connection of a HAM device to the internet, and how to modify this setting, by following the instructions in our article.

Access ports

You can see how to check if the appropriate ports are open for the HAM devices to communicate with the internet and how to troubleshoot the possible problem by following the instructions in our article.

Limited list of devices
In some business environments, there is a less common setting that may prevent the HAM device from connecting to the Internet. This setting is known as "Wireless MAC Filtering." It restricts access to the router by allowing only specific devices based on their MAC addresses.
  • Then go to the "Wireless MAC Filtering" tab. There you will see all the devices that have been given exclusive access through this setting
  • Go to the "Wireless" or "WiFi" tab, from the settings menu of your router
To deal with the obstacles that "Wireless MAC Filtering" may pose, there are two ways to choose from:
  • You can disable the "Wireless MAC Filtering" filtering process altogether by clicking on the "Disable" option
  • Alternatively, in case you wish to keep the setting active, then you can simply add the HAM device you wish to configure to the list of allowed devices, with the MAC Address of the device.

You can see how to add a HAM device to the list of allowed devices by following the detailed instructions in our article.
