Windows 7 system uses routers with Internet access limited prompt network access restricted

Q: The new bought a tl-wr740n router, according to the instructions can be installed after the Internet, but after a break, the lower right corner of the yellow exclamation point, prompted network access restricted. It will be automatically connected again later. It is normal to take a notebook to another place, is there a problem with the Router? My system is the Windows 7 flagship.

A: This is a "common problem" with Windows 7 systems, which can be resolved through Group Policy settings. First, open the Group Policy window, expand Computer configuration → administrative Templates → system →internet Communication Management →internet communication settings, and then in the window on the right, locate the "Turn off activity test for the Windows network connection Status indicator" and, after double-clicking, modify the property to Enabled.
