WIFI always disconnects, and reports "no internet access". It might connect back after some time. It happens in many different locations: at home, in coffee shops etc. My colleague told me that it might be a problem with WIFI adapter in my laptop. It might be loosely connected and overheating. Or might require replacement. Before I go that way I wanted to get second opinion. Thanks.
Right after I lost internet connection I got the following from the Chrome Diagnostics:

EDIT 1: - OS: Windows 8.1 - other devices usually stay connected to wifi router at the time when my laptop drops the connection. - It looks like it depends on how much data I send to the web. For example, If I work with the cloud, and it often then the connection might drop every 5-10 minutes. - The signal is usually good, when it reports "No Internet Access"
