Lately I am getting this weird problem with internet. If I keep my system idle for few hours and then start browsing internet, some websites won't load. If I click speed dial on firefox, nothing happens. I switch on vpn or use different browser to open that website, even then it won't load. Network diagnostics says no problem. Even my router settings won't open in any browser. Only way is I restart my PC and then everything works. What could be the problem ?
Power management of the network card? Device manager > properties of the network card > power management > allow Windows to turn off this device to save power (or similar wording) "Network card" can also be integrated on the motherboard.
ok i remember this option next time. i actually re-installed win 11 , removed win 10 thinking that it has problem.
