Also, how stable is 0.9.9.2 by you? For me the module reboots randomly. I don't understand because with the factory firmware it was okay. I'm using the Uno to power the board like i did it before, i don't think it's a power issue.

I've noticed that 0.9.9.2 will restart a lot when it receives bad commands. Instead of getting stuck in a busy state like would happen in previous firmwares.
Probably because they've added a watchdog option now...

Support watchdog, auto restart when program have errors occurred, AT command: turn on watchdog AT+CSYSWDTENABLE; turn off watchgod: AT+CSYSWDTDISABLE

Try turning off the watchdog to see if it helps.
Though if the watchdog is causing a restart, I think something wrong is happening (commands are being sent to quickly, etc)

I'm running from a lab/bench power supply, so I could see that I never went over current.

Its not a real fix, but I can work around the issue by running WPA with TKIP on my wireless access point.
My wireless router was using WPA2/AES which worked fine with an earlier version, my guess is something about WPA2 or AES is taking longer than the (newly enabled by default?) watchdog timer allows between resets.

Didn't see an obvious place to set the WD timeout in SDK/examples in order to test that theory.
