The EZB is connected to my router. The laptop is connected to the router.
My laptop is not disconnecting to the router or is exhibiting any issues with the network connection or traffic.
Does anyone know why the EZB unexpectedly drops connection to EZ builder?
What conditions cause this is happen?
Does the EZB have an error code stored indicating why the connection was dropped?
Is there a way to test send receive between the EZB and the laptop using EZBuilder? Like a lag test or performance test?

Low battery,
Distance between EZ-B and router (weak signal if EZ-B is too far away from router).
Not suppling enough current (amps) to the EZ-B (using servos will need at least 20 amps. The more amps, the better.)
I've got it hooked up to a 12v 5A power supply plugged into the wall. The EZB and laptop are less then 15 feet from the router.

Would the ezb reset on a brown out?
If your asking about the connection mode (AP/Client modes) then no, it won't reset the connection mode you last set it to.
If your asking about the hardware itself, a power cycle as you have already mentioned will reset the board from a "Brown Out" (board locks up and a solid red LED is illuminated).
The only other thing I can suggest is narrowing down the variables of what's causing the brown out. If you have a powerful enough battery laying around like a LiPo or NiMH, charge it up and plug it in to the EZ-B and see if you experience the same problem.
By the way what power supplies claim that they are rated for might not be what they are actually outputting...
Thanks guys, great suggestions. Will check router issue.
Still on the fence concerning power for the reason I am also powering an Arduino Mega on the same power rail as the ezb and it functions normally when the ezb disconnects. I am not ruling the power issue out yet tho.

It only pulls that much for a fraction of a second when a servo first starts to move. It is called Inrush current (or in-rush current). It doesn't need that much sustained, but it needs to be able to deliver it very quickly in short bursts.
NiMH, SLA and LiPo's (and non rechargeable Lithium) can deliver it. Alkaline can't, which is why EZ-Robot recommends NiMH if using the AA battery holder or LiPo's for longer life and lighter weight.
