I also have a similar problem, but it is still related to a battery problem. My ez-b would lock and wifi would be dropped but it would quickly recover. I was running a battery with 2 high amperage motors on it and it failed to provide enough power to the ez-b. Mine sounds more like a brownout though.

How far is your access point from the robot? Is there a microwave between the robot and the router?

I have never been a wifi fan due to it having flaky issues and a lot of things can interfere. I would start by trying to elementary wifi issues as being a concern first and then start looking at the EZ B. If the access point is close to your ezb, reboot the access point and see if you then keep having issues.

Yeah, did all that....router is pretty close and the only thing which could cause interference would be the Power Supply, pretty unlikely though right?

I reset the EZ-B, let's see if the problem is persistent!

Just wanted to check if there are any know issues! Thanks for chipping in your thoughts on this!

No problem. Wifi can be a pain. I have run on 5 volts without any issue with Wifi though. I don't think it is a power issue for you.

If your smart phone is on your wifi (assuming you have it with you when working with JD) and it is also using wifi, it would be interesting to look at the signal on the smartphone when this happens. I wonder if it drops in signal strength for a few seconds when this happens. The smart phone isnt going to be as visible to any wifi issues because it will just fail over to the provider network, but it does show signal strength at some interval. It would at least help to eliminate wifi as being the issue.

Good luck and I hope this helps some.

I'm having the same issues, EZB alone (no servos) and random disconnects, I'll try different power supplies, if you have a chance try a power supply with more than 7.5v, something like 9V/1A do not connect servos otherwise you fry one by mistake.

I'm trying to understand if the power supply (voltage) can affect the wifi performance, so far i tried 7/2A, 5/10A same issues.

@CochranRobotics

Did you get success with 5v ?

I have the EZ-B connected to 5V/10A power supply, the EZB works but the camera didn't come up neither the EZ-B HD servo respond to commands, can't be a problem of Amps

I had idea that 5V could drive the servo and electronics (camera).

All: Anyone knows if is safe to connect 12V/5A to an EZB (no servos)?

No issue on using 12V with the EZB. I have run 12V without any issue and the spec sheet shows up to 18V i think.

On the board that I am running at 5V/10A I dont see this issue. I dont run a camera from this board nor do I run any servos. I am only running a 4-n-1 sensor. It is being powered by a Castle 5V/10A BEC that is converting from 12V to 5V.

Good to hear I am not the only one having issues....I will keep the post open for a little bit just in case someone still has a contribution!

Btw this forum is awesome...thanks for response time is beyond lightspeed! Thanks everyone!

I am surprised the camera isn't working at 5v. I am not surprised that 7.4v servos don't work at 5v. You can usually (while risking shortened lifespan) run 5v servos at 7.4, but I would not expect the opposite.

As mentioned in the power supplies tutorial and numerous threads, not all power supplies are created equal. Just because it can deliver 10amps steady, doesn't mean it can handle servo inrush current.

Instead of boosting up the amps on the supply, you can try the super cap mod which can bridge the gap for short brownouts: Post 15 of this thread has the super cap mod instructions: https://synthiam.com/Community/Questions/8686&page=2
