Hi All,
having trouble with EZ-B V4 controller intermittently hooking up to wifi with laptop. I have disabled my antivirus and tried through my internal wifi laptop connection and my ASUS wifi usb adapter and will occasionally get a connection that will remain until I disconnect it. I have also tried removing and reinstalling EZ builder and had no luck. I have not changed any configurations since my last connection and still cannot get the controller to link to the computer. I also tried a second EZ B V4 that I have new and it has the same issue. The following is the error message I get through EZ builder...

Can someone please help?
Couple of questions, what type of power are you using to power the EZ-B?
If by battery, is it/are they fully charged?
Do you have anything connected to the EZ-B I.e, servos, sensors, anything connected to the i2c pins like an 8x8 RGB panel?
Have you tried resetting the EZ-B?
Answer Steve's question - i'm wondering if the EZ-B is losing power and rebooting, which results in your laptop connecting to the default network and NOT the EZ-B. This is evident in the error message, that your computer is not actually connected to the EZ-B's WifI and may be connected to your router.
I noticed the error message about "Actively refusing connection" is what your wifi router would respond with NOT the EZ-B. This means you are not actually connected to the WiFi of the ezb. I would recommend following the tutorials of The Robot Program for your product to start - that way you can learn how to connect to a wifi network from your computer. There's fantastic videos that will help.
Lastly, if you experience WiFi saturation in your area, ARC and the EZ-B are not at fault. Uninstalling ARC or rebooting the EZ-B will not fix the saturation of WiFi. But, before we assume that is the case, I suggest following the FAQ and run WiFi Info to see how saturated your area is AND consider changing the WiFi channel in the EZ-B.
The log file shows the EZ-B voltage monitor has been manually lowered to 5v. Are you certain that is enough voltage for your project? Perhaps the project servos/motors are requiring more than 5v and browning out the EZ-B.
Couple of questions, what type of power are you using to power the EZ-B? A 120VAC to 6VDC 6Amp power supply.
Do you have anything connected to the EZ-B I.e, servos, sensors, anything connected to the i2c pins like an 8x8 RGB panel? 1 high torque 12v servo that utilizes a separate 12v power source and the control board for it, which uses the same 6VDC 6Amp power source as the EZ-B and only draws about 350ma and the EZ-B camera.
Have you tried resetting the EZ-B? Yes
Okay, One other question then... does the EZ-B disconnect from your computer when you attempt to move the servo with whatever control or script you’re using to move the servo?
Okay, One other question then... does the EZ-B disconnect from your computer when you attempt to move the servo with whatever control or script you’re using to move the servo? No, but it does not move smooth or all the way. It's kind of jerky as it moves in either direction. Also, I can't connect even if I disconnect the servo and camera. I have no problem connecting to the laptop's wifi, but connecting to ARC is the problem.
As you can sometimes establish and keep an connection for a while to move the servo (hence, the jerky servo movement), I'm wondering if it is a power issue.
Personally, I’d suggest trying to power the EZ-B (with nothing connected to it) with a different power source such as a battery, just to see if you can establish and maintain a connection and eliminate the power supply you’re currently using.
Also, I know you’ve already mentioned it, but double check that your anti virus is actually disabled and not re-enabled itself.
And just out of curiosity, what kind of servo/control board are you using? If you post some specs, a photo and/or a link to the product page, that maybe useful.
For the jerky servo movement, I’m wondering if it is drawing enough current from the separate 12v power supply.
Ok, I noticed when I disconnect from my wifi service from the laptop, I can connect the EZ-B to ARC DJ was right about the wifi modem sharing the same IP address as the EZ-B. So, now how do I change the EZ-B's IP address, so I can connect my internet and EZ-B at the same time? I know DJ made a video about it and I seen it a while back and forgot which one it was, so If anyone can provide the link, I would appreciate it.
I had the same issue with my new TP_Link where the router and the EZB4 shared the same ip address (192.168.1.1)... I just changed my router's default IP address....
