Hi @Carl_Pajak. I have the same problem, with the CHIP dropping off after a time between 2-7 days. Both lights remain on, but I am unable to connect to the CHIP via Wifi, and it doesn't seem to be downloading any packets. The only way to reset it is to power off, then power back on. @Syed, do you track the connections in http://status.outernet.is/ as my receiver is the one in Australia. It is normally green for a few days, then goes orange for a day, then drops off. That may show you how long I typically have for uptime.
It might be the temperature, but I'm not sure. The ambient temperature is only about 20C here during the day. The receiver is in a large plastic box, out of the sunlight. I have tried a number of power supplies and USB cables, and the ones I use at the moment seem to make it boot OK.
