Connection Issues

Skip to comments   Jump to end

I can't connect my EZ-B to my computer, and the tutorials are not helping.  I'm able to get the wifi connection running, I boot up ARC, but the debug log says...

Connection Failed: System.Net.Sockets.SocketException (0x80004005): No connection could be made because the target machine actively refused it 192.168.1.1:23 at System.Net.Sockets.Socket.InternalEndConnect(IAsyncResult asyncResult) at System.Net.Sockets.Socket.EndConnect(IAsyncResult asyncResult) at System.Net.Sockets.TcpClient.EndConnect(IAsyncResult asyncResult) at EZ_B.EZB.Connect(String hostname, Int32 baudRate) Disconnected

What do I do here?

Do you also have a wired connection to your home network, or 2 wifi cards?  This is usually caused by an overlap in IP addresses.  192.168.1.1 is the default address of many home routers.  If you do, unplug the Ethernet connection, or disable the WiFi device connected to your home network until you get connected to the EZ-B.  Once connected, you can change the EZ-B's default address in it's web interface so it does not conflict with your home network.

"you can change the EZ-B's default address in it's web interface so it does not conflict with your home network." How do I do that, and what do I change it to?

without additional networking skills you have two options:

  1. EZB AP Mode Your PC is a client and EZB (192.168.1.1) creates a wifi network and assigns clients ips: 192.168.1.2, 192.168.1.x your PC connects to the EZB's 192.168.1.1 and can only access EZB or other EZB's clients, no internet or access to other home computers.

  2. EZB Client Mode Your EZB is a client and connects to your Home/Office wifi, and your Router assigns an IP.  your PC connects to the EZB's assigned IP

Which of the scenarios you have ?

@ptp I don't know which of those scenarios I have.

  1. Do you have an ethernet cable connecting the computer to a router for internet access?

  2. Does the EZ-Robot EZ-B v4 make a startup chime when it is powered on?

  3. Does the EZ-Robot EZ-B v4 speak and introduce itself?

  4. Did you follow the EZ-Robot connection diagnostic link that's prompted when the connection fails? This is the link: https://synthiam.com/Tutorials/Lesson/14?courseId=4

@Bobsheaux .... I will simplify what ptp asked you.... Does your ezb's led flash blue or green when it is on?.... I am guessing blue so you are AP Mode....

@DJ

  1. Yes. I want to get as much information about how to fix so I'm not stuck diving under my desk to unplug and replug it back a dozen times. ;P
  2. The EZ-B does chime when powered on.
  3. It does speak and introduce itself.
  4. I didn't get a prompt for the diagnostic link, but I did follow that link on my own when it didn't work. I ran through it again, but it's still not working.

@Dunning-Kruger It is flashing blue, yes.

To clarify - you didn't get this prompt when connection failed?

  1. Do you have a virus scanner installed as mentioned in the connection diagnostic trouble shooting guide? (https://synthiam.com/Products/Controls/Overview/Connection-Troubleshooting-17520)

  2. I'm guessing your Ethernet is on the same network as the EZ-B. That is what's causing the connection failure. Which is a rare occurrence, of why you didn't easily come across the solution. If this is the case, the way to change the default ip address of the EZ-Robot EZ-B v4 is here: https://synthiam.com/Tutorials/Lesson/80?courseId=4
