What regulator do you reccomend instead TS1117?
Yes.. I use that. I check all and ESP is very unstable....

Everyone gave me a lot of advice and at the end I believe that I just have to put in more time and perseverance, then I will get there. I will go through everything that was said practically. It might just take more time now since my university is starting now.
Just sucks basically how everything I've been using doesn't seems to be the same methods everyone gets success with.

As mentioned above there is almost always a reason for unreliability and electrical noise is one of the most common with this or any microprocessor.
The other reason I have found is when writing files to the flash memory. I suspect the issues are timing related, because most of my unreliable experiences have occurred when, after updating a file, I put the system to sleep. Perhaps some writes can take a very long time...
As an example of reliability, I installed an ESP-01 on our well pump on November 30, 2014 to monitor the pump operation with a really simple Lua program.
http://benlo.com/esp8266/esp8266Project ... werMonitor
It connected successfully once every 30 seconds when the pump motor was on until December 2015 when it stopped working. It turned out that the cheap 3.3V wallwart power supply had died. I replaced it with a new one and it continues to work day in day out.
The only thing is that it is powered off except when the pump power is on. When it is on, average once a day, it is usually running for about an hour. Once in a while 2 or 3 hours.

Just in case it's not so obvious to everyone, the average multimeter is not possessed of evil spirits
At worst it "looks" like a 1 million Ohm resistor between the leads, in parallel with 10 or so Picofarads of capacitance. But the long test leads will behave like Aerials if used to probe high-impedance, ill-defined inputs (that should otherwise be actively pulled up or down and bypassed for RF frequencies if they present a significant electrical area).
On top of this, the ESP8266 is quite a powerful Radio transmitter and may well appear to have evil influences on nearby devices - including itself if adequate precautions are not taken

They would not be the first thing not to like multimeters sadly.
