Athena will provide some advice.  But before that, I noticed your log says the ARC is outdated. Also, you are a Pro user but using ARC Free. The first recommendation is to update ARC and use the Pro version.

However, disconnecting WiFi network would not be related to ARC - but it’s still worth recommending.

We moved this thread from a General post to a Question. This will allow @athena to provide input on the topic.

Hi Rosspaintman,

It looks like there are a couple of things to consider since you're using the EZB connection via Wi-Fi with the IoTiny.

1. ARC Version & Licensing
Your log indicates that your ARC is out of date, and since you’re a Pro user, it’s best to update to the latest ARC version and use the Pro version. While this may not directly cause Wi-Fi drops, running the most current version can ensure all the stability fixes are in place.
You can update ARC from the Synthiam website here: ARC Downloads.

2. Wi-Fi Connection Issues
The behavior you described-your computer’s Wi-Fi disconnecting when you try to connect to the IoTiny-suggests that the IoTiny might be broadcasting its own network. In many cases, IoTiny devices (and similar controllers) default to acting as a Wi-Fi access point rather than joining an existing network. Here are a few steps to troubleshoot this:

Wi-Fi Mode:

• Check the IoTiny’s Wi-Fi settings in its configuration (often available via its web interface or documentation).
• It might be set to "Access Point" mode. In that configuration, when your computer connects, it takes over the Wi-Fi network interface, which is why your primary Wi-Fi connection drops.
• If you want the IoTiny to join your existing network (client mode), refer to the IoTiny manual to switch it to client mode or "Station" mode.

Network Adapter Considerations:

• If your computer has only one Wi-Fi adapter, it might have difficulty staying connected to your home network and the IoTiny simultaneously. If possible, try using a dedicated USB Wi-Fi adaptor for the IoTiny connection.
• This way, your main connection remains stable while the IoTiny connects using the separate Wi-Fi interface.

Connectivity Duration:

• The connection dropping after a few minutes may indicate that the IoTiny or your computer’s network settings are automatically reverting once the device stops actively streaming or being used. Double-check that all settings (SSID, password, and IP configuration) are correctly configured according to the IoTiny documentation.

3. Additional Guidance
Since the behavior is more related to your Wi-Fi configuration rather than ARC itself, updating the ARC is still a worthwhile step for overall stability but won’t directly affect the Wi-Fi linking.
If you continue to have trouble, verifying how the IoTiny’s Wi-Fi is meant to be used with your computer (as a client vs. an access point) might be the key detail.

Could you confirm which Wi-Fi mode your IoTiny is currently set to? Also, do you have a second Wi-Fi adaptor available to test a dual-adapter setup? These details can help narrow down the solution further.

Let me know if you have any more questions or need further clarification!

If your iotiny disconnects as well, check the power supply voltage and current. Many times ppl overlook the amount of current required to a robot and not providing enough. The iotiny will lock up and disconnect if the current is too low for the peripherals

Hi Rosspaintman,

Here are a few additional points for troubleshooting your IoTiny connection issues:

1. Power Supply Check
   Ensure that the power supply to your IoTiny meets the voltage requirements and, more importantly, has enough current for your entire robot.

   • When the current available is too low for the peripherals, the IoTiny may lock up and drop its connection.
   • Double-check both the voltage and the current specifications of your power supply against what your robot’s components require.

2. Monitor Peripheral Load

   • Consider whether all the attached peripherals and motors are drawing more current than the supply can handle.
   • If possible, measure the voltage at the IoTiny when the peripherals are active to ensure it remains within the correct range.

3. Stability and Consistency

   • If the IoTiny locks up due to undervoltage or insufficient current, it will drop out of connection unexpectedly.
   • Verifying that your power source is robust enough (or considering a separate dedicated power supply for heavy load components) might help maintain a stable connection.

4. Keep ARC Updated
   In parallel to checking the power issues, remember that updating to the latest ARC Pro version ensures you have all the performance and stability fixes that can help overall system reliability, even though the Wi-Fi disconnections are more hardware related.

Could you check your power supply specifications and compare them with the IoTiny’s requirements? Also, if you have a way to monitor the voltage/current when your robot is operating, that might provide clues to any drop that triggers the lock-up.

Let me know if you need further guidance or if there are any specific measurements you can share!
