My laptop just got back from repairs with a fresh install of Windows 10 and a BIOS update. Since then, my wifi connection has been unstable at best. It will remain connected to my network, but suddenly claim there's no internet access. This happens regardless of what network I'm connected to, and other devices remain connected during that time. Usually the problem is fixed by putting the laptop into and then out of airplain mode, but sometimes I actually have to disable and reenable the wireless adapter. I don't know if it recovers on its own given time, as when I notice it's happened I, obviously, am trying to USE the internet.
I've tried fixing this by updating drivers, rolling back drivers, using Windows troubleshooting and Acer Care Center, all to no avail.
