I just received and set up this hotspot yesterday, and at first it seemed to work quite well. But I now find that if I step away from my laptop for 20-30 minutes and return, the wifi has ceased, and when I look at available wifi networks, it is no longer listed. (Other devices - such as my wife's laptop - also don't show it available.) I check the hotspot, and it is still powered up. If I push the hotspot's power button once, within a few seconds it has reappeared among available networks.
I don't want to have to revisit the hotspot to reset it everytime I step away from my laptop. Suggestions?
