Please confirm, if I'm correctly understanding your question.
You have two systems, one with a pcb v1.3 and the other with pcb v2.0. You can get WiFi connection with the one (v2.x) and not with the other (v1.3). Is this right?
On your router try to bind a fixed IP's to the MAC address of each receiver.
The ESP8266 stores the IP of the last successful connection in its internal flash memory, it may be trying to get an IP which the router can't supply to it, because its already used or outside the DHCP range.
If none of this will work, maybe the WiFi module was been damaged.
Do you see the Blue led blinking (on the WiFi module) when the receiver restarts?
