Internet access drops every few minutes

Hello everyone,
I am using a Lenovo laptop for many years and I never had this problem with this laptop before. Everyone in the apartment using the same network. It is a few months that although my connection status shows that it is connected to the internet but I can not open any pages or DL anything. When I use troubleshooter my laptop freeze or just says unable to resolve the problem. When I try to use another router of the building it says unable to connect to internet. What should I do?

Welcome to the forum. Open a CMD prompt then type


Ipconfig /all

Right click to run as administrator (XP users click run after receipt of Windows Security Warning - Open File). When the tool opens click Yes to disclaimer.
Make sure that Addition option is checked.
Press Scan button.
It will produce a log called FRST.txt in the same directory the tool is run from.

The first time the tool is run it generates another log (Addition.txt - also located in the same directory as FRST.exe/FRST64.exe). Please also paste that along with the FRST.txt into your reply.

I assume I suppose to do all these things right after I lost my connection so I wait a few minutes after I restart my computer and try to open a few pages waiting for a few minutes to disconnect. BTW when I restart my computer I have internet access and if I don't open any pages or just start downloading by download manager there is a big chance to stay online without problem.
