I'm not sure if there is some similarity with this issue and my previous post but just in case I'd rather make a separate post. I'm trying to simply reset my EZ-B from Client Mode to default AP mode and it is not resetting. Currently the light is blinking green after I have reset it and I don't hear any verbal messages. I don't hear the message that says it has reset.
I've check the Connection & Troubleshooting page, I've checked the tutorial on How to Connect Your EZ-B v4 to your computer, Resetting Your EZ-B v4 lesson and many pages of Forum posts but not seeing how to resolve this issue. It was working fine yday but since I'm having issues my wifi adapter I just want to reset to default along with my other EZ-B controller.
Upgrade to ARC Pro
ARC Early Access will give you immediate updates and new features needed to unleash your robot's potential!
Just speculation here but if this continues it's possible that little reset button is faulty.
the reset button takes approx 500 milliseconds (half a second) to register that it was pushed.

If one ezb is acting a little funny with the reset switch, I wonder if the button is a tiny bit offset or a little buggy.
(EZ2)=EZ-B that had issue resetting but shows up in wifi list
@DJ thanks for those links. Those were the ones I reviewed before I posted. @Dave Shulpius I'm using the same tool(i.e. a very small flat end hex tool) that fits perfectly in the slot.
EZ1 resets fine with no problem with the exception of the wifi list issue. With EZ2 I do hear the button click so I know it's pressed. I will monitor for awhile to see. @DJ to answer your other question, EZ2 is not the one I'm having trouble with showing in my wifi list. This one shows up every time I plug it in. EZ1 is the one that doesn't show up consistently . I'm thinking my wifi card is working ok because EZ2 shows up great all the time.
I have powered down many times and EZ1 will occasionally show up than disappear and never return. *sick* . Also I noticed a new issue is that when I plug in EZ2 and it shows in wifi list and than I plug in EZ1, they both disappear and when I unplug EZ1 than EZ2 shows up in the list. I'm really confused by EZ1 and what it's doing. I guess it could be my wifi card but I'm not sure since EZ2 shows up fine. Sorry for long response but just trying to explain it as clear as possible . Unless anything changes I guess I should purchase a new wifi card.
Once again thanks for continued help with this.
When I go to a con or anywhere what is the best method to stay connected to my EZ-B controller besides not being to far from my robot . And along these lines, what is the average operating distance that I could operate my robot before losing a connection? At home I can go about 10-15 feet before I hear the EZ-B disconnect but at a convention it could vary i'm guessing.
Lastly I noticed that my motors kept turning when I got disconnected from the EZ-B, how would I preempt something like this?
Here is a good FAQ about WiFi: http://www.ez-robot.com/Tutorials/FAQ.aspx#9
As for your second question, the motors will continue to operate when the ez-b disconnects because the last signal transmitted from the ez-b maintains in the HBridge. This mean the motor driver (hbridge) continues to operate with the last instruction it received.
If i told you to walk forward, and i died... you would continue walking forward for ever because i'm no longer present to tell you when to stop.
There are quite a few threads with discussion on this topic. How to stop the motors when the ez-b disconnects. It can be done by creating a small circuit which monitors the ez-b led status, but that's not an easy job and i highly DO NOT recommend it.
Add a safety switch to your robot so if it does disconnect and "run away", you can easily flick a switch which cuts power to the hbridge and stops the wheels
Lastly, you can monitor this thread for @ptp awesome firmware update, when it is available: http://www.ez-robot.com/Community/Forum/Thread?threadId=9395
