some aditional info . i use two old ezbv4 . the one connected to  number 2 is the one that keeps disconnecting , and after that the ezbv4  will not connect untill i reboot . it also changes its IP adres avery time .  @athena what do you think needs to be done ?

Thank you for providing additional information. It seems like the EZ-B v4 connected to number 2 is experiencing connectivity issues, including frequent disconnections and changing IP addresses. Here are some steps to diagnose and resolve the issue:

Potential Causes and Solutions

1. Network Configuration

• Static IP Address: Configure the EZ-B v4 to use a static IP address to prevent it from changing every time it reconnects.
• Wi-Fi Signal Strength: Ensure that the EZ-B v4 is within a strong Wi-Fi signal range. Weak signals can cause frequent disconnections.

2. Firmware and Software Updates

• Update Firmware: Ensure that the EZ-B v4 is running the latest firmware. Sometimes, firmware updates can resolve connectivity issues.
• Update ARC: Make sure you have the latest version of ARC installed.

3. Power Supply Stability

• Check Power Supply: Ensure that the power supply to the EZ-B v4 is stable and not fluctuating. An unstable power supply can cause connectivity issues.
• Use a Different Power Supply: Try using a different power supply to see if the issue persists.

4. Network Interference

• Check for Interference: Ensure that there are no sources of Wi-Fi interference near your setup, such as other Wi-Fi networks, microwaves, or cordless phones.
• Change Wi-Fi Channel: If possible, change the Wi-Fi channel on your router to reduce interference.

5. Hardware Issues

• Inspect Hardware: Check the EZ-B v4 for any visible signs of damage or wear. Sometimes, hardware issues can cause connectivity problems.
• Test with Another EZ-B v4: If you have another EZ-B v4, try swapping it with the problematic one to see if the issue persists.

Steps to Diagnose and Resolve the Issue

1. Configure Static IP Address

solved . it was a slow internet .

I'm glad to hear that the issue has been resolved! Slow internet can indeed cause connectivity problems, including frequent disconnections and changing IP addresses. If you have any more questions or need further assistance with your robot project, feel free to ask. Happy building and programming with ARC!

I'm glad you found a solution. You mentioned in a different post that you were going to get a new provider or upgrade your service plan. Is this what fixed your issue?

In the past I've assigned static IP addresses to EZBs in my router and that worked pretty well. However after upgrading my home network and making sure I had a strong and stable signal for the EZB's ended the need for the static IP.

Also, I've known a couple people who had 2 EZB's sitting too close to each other and being that close interfered with their network connection. However that was many years ago and before the EZB V4 came out. Perhaps that issue was solved with the new board or there were other things happening with their connection (slow, weak)? In the past I've operated two EZB within 3 inches of each other and had no issues but I have a strong home network and have the latest EZB V4 released. You mentioned that upir big EZB's are old. Do they have boards prior to the V4 release? Have you ever updated their firmware?
