I am using TP-Link W8968 model since last year. Since last 3-4 days, the internet works fine without any problem but suddenly after few min or hours, internet light and LAN light continuously blinking even I don't surf anything.

To find out what is happening in the background and it is something updating, when I see through, task manager - performance tab and find in Ethernet, not much data sending or receiving

Sometimes it went to 0 but still lights keep blinking, and the I can't access my internet, even all the lights are ON. Then I have to restart the PC, and then everything started working again, but this is annoying me after some few min or hours.

Please help, I am using Win10 and never happened such type of problems before.
