Browsers losing Internet connection periodically

[Anmol Singh]

Since a week, my computer's internet connectivity is experiencing some issues. The internet connection is staying active in a way, but losing partially after a certain amount of time.

All browsers start to show "ERR_CONNECTION_FAILED", apps and games gets partial internet connectivity, like in WhatsApp exchange of text messages happens, but no media or status, in game, many functionalities loses connection, like voice chat, text chat and changing settings, etc. 

I can't find any fix which is permanent, only a full system restart helps, but after sometime, again the same disconnection. Whereas, the hotspot that this same system is emitting, that doesn't loses any connection, with the hotspot, I can access the full internet on my phone. 

Please help to fix this, I can't understand if this is a problem of antivirus, or windows update or something else.

Thank You

@Anmol Singh Welcome.

When loosing connection and staying active please proceed with command “ipconfig /all” ?

Hello @Anmol Singh, 

You reported that the issue had returned.

The procedure is a once only, if the issue persists, & after uninstalling the software, saving License information only & a clean install, log the issue with Support. 

Thank you?
