Connectivity Issues

Sometimes Feem devices do not detect each other. Luckily enough, there's always a fix.

Feem devices should automatically detect each other, as long as all the devices are in the same network.

Most connectivity issues are usually linked to having a firewall on your desktop PC or laptop that blocks Feem from working properly.

Also, you may have difficulties connecting to public Wi-Fis like those provided by hotels, Starbucks, or your railway. These public Wi-Fis usually block applications like Feem. In that case, you can use Feem’s Wi-Fi Direct

My devices do not detect each other!

The number one reason Feem doesn’t detect other devices is because the devices are not in the same local/Wi-Fi network.

Follow the checklist below:

  • Have you installed Feem v4 on all your devices? You need at least two devices running Feem v4 in your local network.
  • Note that Feem v3 is not compatible with Feem v4. You need to install Feem v4 on all of your devices. Feem v3 and Feem v4 both have different logos.
  • Have you checked that all your Feem devices are on the same Wi-Fi network ?
  • Have you checked your Firewall settings for Feem ? If your firewall is on, ensure that Feem is allowed by your firewall. For Windows 7 users, ensure that Feem is allowed in your firewall settings in both Public and Home networks.
  • Can you make sure that your router/firewall doesn’t block UDP broadcasts from Feem? If it does, you’ll need to ensure your router/firewall allows traffic from UDP port 45001.
  • Can you make sure that your router/firewall doesn’t block TCP traffic from Feem ? If it does, you’ll need to ensure your router/firewall allows traffic from TCP port 45001.

My iOS devices do not detect other Feem devices

Devices running iOS (iphones and iPads) need special permissions for Feem to work properly.

Go to your iOS device settings, scroll down till you see the Feem app, select the Feem app, and ensure the following permissions are set:

  • Location: While Using. Feem does not use your location information in any form, but Apple assumes your location information might get leaked if you use Wi-Fi. That’s why location permissions have to be granted.

  • Photo: All Photos. Feem does not do anything nefarious with your Photo gallery. But we need access to all your photos so that it can be easier for you to select multiple photos within the Feem app. Your photos never get uploaded unto any server. They never leave your devices.

  • Local Network: On. As from iOS 14, Feem needs this permission to be granted in order to discover other Feem devices around you.

Once all the above permissions have been granted, restart the Feem app on your iOS device.

Is Feem v4 installed on all of your devices?

Make sure Feem v4 is installed on all of your devices.

Feem v3 is outdated and no longer supported. For those of you still running Feem v3, note that Feem v3 is not compatible with Feem v4.

Do I really need a Wi-Fi router to use Feem?

No Wi-Fi router, No Problem.

Create a portable Wi-Fi hotspot on your device, and share your connection with other devices.

If you need help setting up a Wi-Fi hotspot on your iPhone, please consult this article .

If you need help setting up a Wi-Fi hotspot on your Android device, please consult this article .

Another way to create a Wi-Fi network is by using Feem’s Wi-Fi Direct feature on devices that support it (Windows 10 and Android). If your device supports Wi-Fi direct, you will see the Wi-Fi Direct option inside Feem. Activate Wi-Fi Direct Mode by clicking on the Wi-Fi Direct option inside Feem.

Only one of of your devices needs to have Wi-Fi Direct enabled.

Upon activation, a random Wi-Fi hotspot is created with the name of the device, with a random password. Your other devices are expected to join this new Wi-Fi hotspot, which will show up in their list of Wi-Fi hotspots.

Are some of your devices connected via Wi-Fi and others via a cable LAN?

Feem should work great for devices connected to their router via LAN cable. In fact, Feem works faster with a LAN cable than with Wi-Fi. If LAN cable and Wi-Fi devices don’t detect each other, please ensure your router isn’t creating two separate networks for LAN cables and Wi-Fi connections. Also check if you have any firewalls installed on your PC.

Are all of your devices on the same Wi-Fi network?

The easiest way to check if all of your devices are connected to the same Wi-Fi network is to check inside Feem. Feem displays the name of the Wi-Fi network it is connected to at the top of the app.

Does your Wi-Fi router have a firewall?

Some routers might be configured to allow network traffic only from specific apps.

Your router needs to allow BOTH:

  • TCP port 45001 and
  • UDP port 45001

for Feem to function properly.

Do you have a firewall installed on your PC ?

For Feem to work properly, you need to configure your firewall to allow the Feem app as an exception.

If your firewall doesn’t give you the option to allow certain apps as exceptions, then make sure your firewall allows exceptions for the following ports:

  • TCP Port 45001 and
  • UDP Port 45001

Linux users can use the following video to guide them on how to setup firewall settings on their box.
