It's either an issue of the free house WiFi or of your laptop.
So try another device (another laptop or your phone with data disabled) on your WiFi and try your laptop elsewhere (with a friend or a free hotspot). Then you know.
If it's your laptop and it came 'suddenly' try System Restore back to yesterday or so.
Internet issue:when use free house wi fi only get yahoo, youtube and Google. No other sites. Was fine for 1 year. I used to get Amazon but no anymore
Have to use hotspot on phone to connect to other sites.
