As of the 18th of this month my internet has recently been disconnecting when streaming videos online on both Chrome and Firefox with and without a wired internet connection on Windows 10.
Usually, the computer picks up and automatically connects to networks however the 'home' section will say disconnected. Usually resetting the computer will resolve the issue for a short while.
I have tried turning off firewalls and checking the computer for viruses using AVG, neither of which have made a difference.
I have tried using the troubleshooter which appears when the internet disconnects which usually either temporarily fixes the issue, or says that the internet is connected and that no issue has been found despite the internet not being usable and 'home' still saying disconnected.
All other devices in my house work flawlessly with the internet and my computer is the closest device to the modem.
Really hoping someone might be able to offer a solution...
Could well be a line fault. Try rebooting the router for now. See if that helps. Check your down and up speeds with your favourite speed checker every few hours or less just to see what results you get.
