1. Have you tried restarting the computer? try it a couple times and if you get no results,
2. restore the system to the last restore point, be it from yesterday or day/s before.
3. If nothing has changed, log in to the router and change the Wi-Fi channel from channel 6 to channel 11. You can do this from any computer that uses the same Wi-Fi modem. If changing to channel 11 solves the issue, try different channels untill the connection is again lost, and go back to the lowest channel that worked.
4. If changing channels did not work, try a Wi-Fi analyzer app... there's a Wi-Fi booster you could try instead of suggestion #3.
