Connect timeout error

hi april brothers

i have a really strange problem. i ordered a new series of rev1 micros and i can not send requests anymore. first i thought it’s my code, but after hours of reseting router, switching code i tried the old working temperature logging tutorial again, and it’s not working as i did with the version order of cactus micros… i get:

AT+CIPSEND=85
connect timeout
AT+CIPCLOSE
ERROR

connection to wlan-router seems to work, but otherwise it fails. i tested with two fresh devices out of the box. same result. i changed router settings, no success…

the temperature logging example is not working anymore, i am puzzled.

Could you please show me the sketch?
